style: Make main green again

The systemd unit file uses `ProtectSystem=strict`, which makes almost
every directory read-only. This can cause backups to not work, even if
the directory is granted the correct permissions and ownership to the
`conduwuit` user.

The `ReadWritePaths` setting lets you specify which directories are
exempt from being made read-only by `ProtectSystem=strict`.

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, caste, color, religion, or sexual
-identity and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the overall
-  community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or advances of
-  any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email address,
-  without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement over Matrix at [#continuwuity:continuwuity.org](https://matrix.to/#/#continuwuity:continuwuity.org?via=continuwuity.org&via=ellis.link&via=explodie.org&via=matrix.org) or email at <tom@tcpip.uk>, <jade@continuwuity.org> and <nex@continuwuity.org> respectively.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.

+#### Writing news fragments
+
+In order to make writing our changelogs easier, we make use of [Towncrier]. Towncrier builds changelogs based on
+"news fragments", which are little markdown files in the `changelog.d/` directory that describe individual changes.
+
+When you make a pull request that changes functionality, fixes a bug, or adds documentation, please add a news fragment
+describing your change. The file name *MUST* be in the format of `{pull_request_number}.{type}`, where `{type}` is one
+of the following:
+
+- `feature` - for new features
+- `bugfix` - for bug fixes
+- `doc` - for documentation changes
+- `misc` - for other changes that don't fit the above categories
+
+For example:
+
+```bash
+$ echo "Fixed the quantum flux stabiliser. Contributed by @alice." > changelog.d/42.bugfix
+```
+
+(Note: If you want to credit yourself, you should reference your forgejo handle, however links to other platforms are also acceptable.)
+
+When the next release is made, Towncrier will automatically include your news fragment in the changelog.
+
+You can read more about writing news fragments in the [Towncrier tutorial][tt].

+:::tip Avoid port clashes between the two services

+# in your coturn.conf
+min-port=50201
+max-port=65535

+:::
+
+Generate a long random secret for LiveKit, and add it to your coturn config under the `static-auth-secret` option. You can add as many secrets as you want, so set a different one for LiveKit to use.
+
+Then configure LiveKit, making sure to replace `COTURN_SECRET` with the one you generated:
+

+    - host: coturn.example.com
+      port: 3478
+      protocol: udp

+      port: 5349
+      protocol: tls # Only if you have already set up TLS in your coturn
+      secret: "COTURN_SECRET"
+```
+
+Restart LiveKit and coturn to apply these changes.
+
+## Testing
+
+To test that LiveKit is successfully integrated with Continuwuity, you will need to replicate its [Token Exchange Flow](https://github.com/element-hq/lk-jwt-service#%EF%B8%8F-how-it-works--token-exchange-flow).
+
+First, you will need an access token for your current login session. These can be found in your client's settings or obtained via [this website](https://timedout.uk/mxtoken.html).
+
+Then, using that token, request another OpenID token for use with the lk-jwt-service:
+
+```bash
+~$ curl -X POST -H "Authorization: Bearer <session-access-token>" \
+  https://matrix.example.com/_matrix/client/v3/user/@user:example.com/openid/request_token
+{"access_token":"<openid_access_token>","token_type":"Bearer","matrix_server_name":"example.com","expires_in":3600}
+```
+
+Next, create a `payload.json` file with the following content:
+
+<details>
+
+<summary>`payload.json`</summary>
+
+```json
+{
+    "room_id": "abc",
+    "slot_id": "xyz",
+    "openid_token": {
+        "matrix_server_name": "example.com",
+        "access_token": "<openid_access_token>",
+        "token_type": "Bearer"
+    },
+    "member": {
+        "id": "xyz",
+        "claimed_device_id": "DEVICEID",
+        "claimed_user_id": "@user:example.com"
+    }
+}
+```
+
+Replace `matrix_server_name` and `claimed_user_id` with your information, and `<openid_access_token>` with the one you got from the previous step. Other values can be left as-is.
+
+</details>
+
+You can then send this payload to the lk-jwt-service:
+
+```bash
+~$ curl -X POST -d @payload.json https://livekit.example.com/get_token
+{"url":"wss://livekit.example.com","jwt":"a_really_really_long_string"}
+```
+
+The lk-jwt-service will, after checking against Continuwuity, answer with a `jwt` token to create a LiveKit media room. Use this token to test at the [LiveKit Connection Tester](https://livekit.io/connection-test). If everything works there, then you have set up LiveKit successfully!
+
+## Troubleshooting
+
+To debug any issues, you can place a call or redo the Testing instructions, and check the container logs for any specific errors. Use `docker-compose logs --follow` to follow them in real-time.
+
+### Common errors in Element Call UI
+
+- `MISSING_MATRIX_RTC_FOCUS`: LiveKit is missing from Continuwuity's config file
+- "Waiting for media" popup always showing: a LiveKit URL has been configured in Continuwuity, but your client cannot connect to it for some reason
+
+### Docker loopback networking issues
+
+Some distros do not allow Docker containers to connect to its host's public IP by default. This would cause `lk-jwt-service` to fail connecting to `livekit` or `continuwuity` on the same host. As a result, you would see connection refused/connection timeouts log entries in the JWT service, even when `LIVEKIT_URL` has been configured correctly.
+
+To alleviate this, you can try one of the following workarounds:
+
+- Use `network_mode: host` for the `lk-jwt-service` container (instead of the default bridge networking).
+
+- Add an `extra_hosts` file mapping livekit's (and continuwuity's) domain name to a localhost address:
+
+    ```diff
+    # in docker-compose.yaml
+    services:
+      lk-jwt-service:
+        ...
+    +    extra_hosts:
+    +     - "livekit.example.com:127.0.0.1"
+    +     - "matrix.example.com:127.0.0.1"
+    ```
+
+- (**untested, use at your own risk**) Implement an iptables workaround as shown [here](https://forums.docker.com/t/unable-to-connect-to-host-service-from-inside-docker-container/145749/6).
+
+After implementing the changes and restarting your compose, you can test whether the connection works by cURLing from a sidecar container:
+
+```bash
+~$ docker run --rm --net container:lk-jwt-service docker.io/curlimages/curl https://livekit.example.com
+OK
+```
+
+### Workaround for non-federating servers
+
+When deploying on servers with federation disabled (`allow_federation = false`), LiveKit will fail as it can't fetch the required [OpenID endpoint](https://spec.matrix.org/v1.17/server-server-api/#get_matrixfederationv1openiduserinfo) via federation paths.
+
+As a workaround, you can enable federation, but forbid all remote servers via the following config parameters:
+
+```toml
+### in your continuwuity.toml file ###
+allow_federation = true
+forbidden_remote_server_names = [".*"]
+```
+
+Subscribe to issue [!1440](https://forgejo.ellis.link/continuwuation/continuwuity/issues/1440) for future updates on this matter.

+Get a working Continuwuity server with an admin user in four steps:
+
+#### Prerequisites
+
+Continuwuity requires HTTPS for Matrix federation. You'll need:
+
+- A domain name pointing to your server
+- A reverse proxy with SSL/TLS certificates (Traefik, Caddy, nginx, etc.)
+
+See [Docker Compose](#docker-compose) for complete examples.
+
+#### Environment Variables
+
+- `CONTINUWUITY_SERVER_NAME` - Your Matrix server's domain name
+- `CONTINUWUITY_DATABASE_PATH` - Where to store your database (must match the
+  volume mount)
+- `CONTINUWUITY_ADDRESS` - Bind address (use `0.0.0.0` to listen on all
+  interfaces)
+- `CONTINUWUITY_ALLOW_REGISTRATION` - Set to `false` to disable registration, or
+  use with `CONTINUWUITY_REGISTRATION_TOKEN` to require a token (see
+  [reference](../reference/environment-variables.mdx#registration--user-configuration)
+  for details)
+
+See the
+[Environment Variables Reference](../reference/environment-variables.mdx) for
+more configuration options.
+
+#### 1. Pull the image
 
 ```bash
-docker run -d -p 8448:6167 \
-    -v db:/var/lib/continuwuity/ \
-    -e CONTINUWUITY_SERVER_NAME="your.server.name" \
-    -e CONTINUWUITY_ALLOW_REGISTRATION=false \
-    --name continuwuity $LINK
+docker pull forgejo.ellis.link/continuwuation/continuwuity:latest
 ```
 
-or you can use [Docker Compose](#docker-compose).
+#### 2. Start the server with initial admin user
 
-The `-d` flag lets the container run in detached mode. You may supply an
-optional `continuwuity.toml` config file, the example config can be found
-[here](../reference/config.mdx). You can pass in different env vars to
-change config values on the fly. You can even configure Continuwuity completely by
-using env vars. For an overview of possible values, please take a look at the
-<a href="/examples/docker-compose.yml" target="_blank">`docker-compose.yml`</a> file.
+```bash
+docker run -d \
+  -p 6167:6167 \
+  -v continuwuity_db:/var/lib/continuwuity \
+  -e CONTINUWUITY_SERVER_NAME="matrix.example.com" \
+  -e CONTINUWUITY_DATABASE_PATH="/var/lib/continuwuity" \
+  -e CONTINUWUITY_ADDRESS="0.0.0.0" \
+  -e CONTINUWUITY_ALLOW_REGISTRATION="false" \
+  --name continuwuity \
+  forgejo.ellis.link/continuwuation/continuwuity:latest \
+  /sbin/conduwuit --execute "users create-user admin"
+```
 
-If you just want to test Continuwuity for a short time, you can use the `--rm`
-flag, which cleans up everything related to your container after you stop
-it.
+Replace `matrix.example.com` with your actual server name and `admin` with
+your preferred username.
+
+#### 3. Get your admin password
+
+```bash
+docker logs continuwuity 2>&1 | grep "Created user"
+```
+
+You'll see output like:
+
+```
+Created user with user_id: @admin:matrix.example.com and password: `[auto-generated-password]`
+```
+
+#### 4. Configure your reverse proxy
+
+Configure your reverse proxy to forward HTTPS traffic to Continuwuity. See
+[Docker Compose](#docker-compose) for examples.
+
+Once configured, log in with any Matrix client using `@admin:matrix.example.com`
+and the generated password. You'll automatically be invited to the admin room
+where you can manage your server.
 
 ### Docker Compose
 
-If the `docker run` command is not suitable for you or your setup, you can also use one
-of the provided `docker-compose` files.
+Docker Compose is the recommended deployment method. These examples include
+reverse proxy configurations for Matrix federation.
 
-Depending on your proxy setup, you can use one of the following files:
+#### Matrix Federation Requirements
 
-### For existing Traefik setup
+For Matrix federation to work, you need to serve `.well-known/matrix/client` and
+`.well-known/matrix/server` endpoints. You can achieve this either by:
+
+1. **Using a well-known service** - The compose files below include an nginx
+   container to serve these files
+2. **Using Continuwuity's built-in delegation** (easier for Traefik) - Configure
+   delegation files in your config, then proxy `/.well-known/matrix/*` to
+   Continuwuity
+
+**Traefik example using built-in delegation:**
+
+```yaml
+labels:
+  traefik.http.routers.continuwuity.rule: >-
+    (Host(`matrix.example.com`) ||
+     (Host(`example.com`) && PathPrefix(`/.well-known/matrix`)))
+```
+
+This routes your Matrix domain and well-known paths to Continuwuity.
+
+#### Creating Your First Admin User
+
+Add the `--execute` command to create an admin user on first startup. In your
+compose file, add under the `continuwuity` service:
+
+```yaml
+services:
+    continuwuity:
+        image: forgejo.ellis.link/continuwuation/continuwuity:latest
+        command: /sbin/conduwuit --execute "users create-user admin"
+        # ... rest of configuration
+```
+
+Then retrieve the auto-generated password:
+
+```bash
+docker compose logs continuwuity | grep "Created user"
+```
+
+#### Choose Your Reverse Proxy
+
+Select the compose file that matches your setup:
+
+:::note DNS Performance
+Docker's default DNS resolver can cause performance issues with Matrix
+federation. If you experience slow federation or DNS timeouts, you may need to
+use your host's DNS resolver instead. Add this volume mount to the
+`continuwuity` service:
+
+```yaml
+volumes:
+  - /etc/resolv.conf:/etc/resolv.conf:ro
+```
+
+See [Troubleshooting - DNS Issues](../troubleshooting.mdx#potential-dns-issues-when-using-docker)
+for more details and alternative solutions.

-
-### Build
-
-Official Continuwuity images are built using **Docker Buildx** and the Dockerfile found at [`docker/Dockerfile`][dockerfile-path]. This approach uses common Docker tooling and enables efficient multi-platform builds.
-
-The resulting images are widely compatible with Docker and other container runtimes like Podman or containerd.
-
-The images *do not contain a shell*. They contain only the Continuwuity binary, required libraries, TLS certificates, and metadata.

-docker buildx build --load --tag continuwuity:latest -f docker/Dockerfile .
-
-# Example: Build for specific platforms and push to a registry.
-# docker buildx build --platform linux/amd64,linux/arm64 --tag registry.io/org/continuwuity:latest -f docker/Dockerfile . --push

-# Example: Build binary optimised for the current CPU (standard release profile)
-# docker buildx build --load \
-#   --tag continuwuity:latest \
-#   --build-arg TARGET_CPU=native \
-#   -f docker/Dockerfile .

-# Example: Build maxperf variant (release-max-perf profile with LTO)
-# Optimised for runtime performance and smaller binary size, but requires longer build time
-# docker buildx build --load \
-#   --tag continuwuity:latest-maxperf \
-#   --build-arg TARGET_CPU=native \
-#   --build-arg RUST_PROFILE=release-max-perf \
-#   -f docker/Dockerfile .

-As a container user, you probably know about Traefik. It is an easy-to-use
-reverse proxy for making containerized apps and services available through the
-web. With the Traefik-related docker-compose files provided above, it is equally easy
-to deploy and use Continuwuity, with a small caveat. If you have already looked at
-the files, you should have seen the `well-known` service, which is the
-small caveat. Traefik is simply a proxy and load balancer and cannot
-serve any kind of content. For Continuwuity to federate, we need to either
-expose ports `443` and `8448` or serve two endpoints: `.well-known/matrix/client`
-and `.well-known/matrix/server`.
-
-With the service `well-known`, we use a single `nginx` container that serves
-those two files.
-
-Alternatively, you can use Continuwuity's built-in delegation file capability. Set up the delegation files in the configuration file, and then proxy paths under `/.well-known/matrix` to continuwuity. For example, the label ``traefik.http.routers.continuwuity.rule=(Host(`matrix.ellis.link`) || (Host(`ellis.link`) && PathPrefix(`/.well-known/matrix`)))`` does this for the domain `ellis.link`.

+[Building Docker Images](../development/index.mdx#building-docker-images)
+section in the development documentation.

 # Continuwuity for FreeBSD
 
-Continuwuity currently does not provide FreeBSD builds or FreeBSD packaging. However, Continuwuity does build and work on FreeBSD using the system-provided RocksDB.
+Continuwuity doesn't provide official FreeBSD packages; however, a community-maintained set of packages is available on [Forgejo](https://forgejo.ellis.link/katie/continuwuity-bsd). Note that these are provided as standalone packages and are not part of a FreeBSD package repository (yet), so updates need to be downloaded and installed manually.
 
-Contributions to get Continuwuity packaged for FreeBSD are welcome.
+Please see the installation instructions in that repository. Direct any questions to its issue tracker or to [@katie:kat5.dev](https://matrix.to/#/@katie:kat5.dev).

-# Contributing guide
-
-This page is about contributing to Continuwuity. The
-[development](./index.mdx) and [code style guide](./code_style.mdx) pages may be of interest for you as well.
-
-If you would like to work on an [issue][issues] that is not assigned, preferably
-ask in the Matrix room first at [#continuwuity:continuwuity.org][continuwuity-matrix],
-and comment on it.
-
-### Code Style
-
-Please review and follow the [code style guide](./code_style) for formatting, linting, naming conventions, and other code standards.
-
-### Pre-commit Checks
-
-Continuwuity uses pre-commit hooks to enforce various coding standards and catch common issues before they're committed. These checks include:
-
-- Code formatting and linting
-- Typo detection (both in code and commit messages)
-- Checking for large files
-- Ensuring proper line endings and no trailing whitespace
-- Validating YAML, JSON, and TOML files
-- Checking for merge conflicts
-
-You can run these checks locally by installing [prefligit](https://github.com/j178/prefligit):
-
-
-```bash
-# Requires UV: https://docs.astral.sh/uv/getting-started/installation/
-# Mac/linux: curl -LsSf https://astral.sh/uv/install.sh | sh
-# Windows: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
-
-# Install prefligit using cargo-binstall
-cargo binstall prefligit
-
-# Install git hooks to run checks automatically
-prefligit install
-
-# Run all checks
-prefligit --all-files
-```
-
-Alternatively, you can use [pre-commit](https://pre-commit.com/):
-```bash
-# Requires python
-
-# Install pre-commit
-pip install pre-commit
-
-# Install the hooks
-pre-commit install
-
-# Run all checks manually
-pre-commit run --all-files
-```
-
-These same checks are run in CI via the prefligit-checks workflow to ensure consistency. These must pass before the PR is merged.
-
-### Running tests locally
-
-Tests, compilation, and linting can be run with standard Cargo commands:
-
-```bash
-# Run tests
-cargo test
-
-# Check compilation
-cargo check --workspace --features full
-
-# Run lints
-cargo clippy --workspace --features full
-# Auto-fix: cargo clippy --workspace --features full --fix --allow-staged;
-
-# Format code (must use nightly)
-cargo +nightly fmt
-```
-
-### Matrix tests
-
-Continuwuity uses [Complement][complement] for Matrix protocol compliance testing. Complement tests are run manually by developers, and documentation on how to run these tests locally is currently being developed.
-
-If your changes are done to fix Matrix tests, please note that in your pull request. If more Complement tests start failing from your changes, please review the logs and determine if they're intended or not.
-
-[Sytest][sytest] is currently unsupported.
-
-### Writing documentation
-
-Continuwuity's website uses [`mdbook`][mdbook] and is deployed via CI using Cloudflare Pages
-in the [`documentation.yml`][documentation.yml] workflow file. All documentation is in the `docs/`
-directory at the top level.
-
-To build the documentation locally:
-
-1. Install mdbook if you don't have it already:
-   ```bash
-   cargo install mdbook # or cargo binstall, or another method
-   ```
-
-2. Build the documentation:
-   ```bash
-   mdbook build
-   ```
-
-The output of the mdbook generation is in `public/`. You can open the HTML files directly in your browser without needing a web server.
-
-
-### Commit Messages
-
-Continuwuity follows the [Conventional Commits](https://www.conventionalcommits.org/) specification for commit messages. This provides a standardized format that makes the commit history more readable and enables automated tools to generate changelogs.
-
-The basic structure is:
-
-```
-<type>[(optional scope)]: <description>
-
-[optional body]
-
-[optional footer(s)]
-```
-
-The allowed types for commits are:
-- `fix`: Bug fixes
-- `feat`: New features
-- `docs`: Documentation changes
-- `style`: Changes that don't affect the meaning of the code (formatting, etc.)
-- `refactor`: Code changes that neither fix bugs nor add features
-- `perf`: Performance improvements
-- `test`: Adding or fixing tests
-- `build`: Changes to the build system or dependencies
-- `ci`: Changes to CI configuration
-- `chore`: Other changes that don't modify source or test files
-
-Examples:
-```
-feat: add user authentication
-fix(database): resolve connection pooling issue
-docs: update installation instructions
-```
-
-The project uses the `committed` hook to validate commit messages in pre-commit. This ensures all commits follow the conventional format.
-
-### Creating pull requests
-
-Please try to keep contributions to the Forgejo Instance. While the mirrors of continuwuity
-allow for pull/merge requests, there is no guarantee the maintainers will see them in a timely
-manner. Additionally, please mark WIP or unfinished or incomplete PRs as drafts.
-This prevents us from having to ping once in a while to double check the status
-of it, especially when the CI completed successfully and everything so it
-*looks* done.
-
-Before submitting a pull request, please ensure:
-1. Your code passes all CI checks (formatting, linting, typo detection, etc.). Run pre-commit for this.
-2. Your code follows the [code style guide](./code_style)
-3. Your commit messages follow the conventional commits format
-4. Tests are added for new functionality
-5. Documentation is updated if needed
-6. You have written a [news fragment](#writing-news-fragments) for your changes
-
-Direct all PRs/MRs to the `main` branch.
-
-By sending a pull request or patch, you are agreeing that your changes are
-allowed to be licenced under the Apache-2.0 licence and all of your conduct is
-in line with the Contributor's Covenant, and continuwuity's Code of Conduct.
-
-Contribution by users who violate either of these code of conducts may not have
-their contributions accepted. This includes users who have been banned from
-continuwuity Matrix rooms for Code of Conduct violations.

-#### Writing news fragments
-
-In order to make writing our changelogs easier, we make use of [Towncrier]. Towncrier builds changelogs based on
-"news fragments", which are little markdown files in the `changelog.d/` directory that describe individual changes.
-
-When you make a pull request that changes functionality, fixes a bug, or adds documentation, please add a news fragment
-describing your change. The file name *MUST* be in the format of `{pull_request_number}.{type}`, where `{type}` is one
-of the following:
-
-- `feature` - for new features
-- `bugfix` - for bug fixes
-- `doc` - for documentation changes
-- `misc` - for other changes that don't fit the above categories
-
-For example:
-
-```bash
-$ echo "Fixed the quantum flux stabiliser. Contributed by @alice." > changelog.d/42.bugfix
-```
-
-(Note: If you want to credit yourself, you should reference your forgejo handle, however links to other platforms are also acceptable.)
-
-When the next release is made, Towncrier will automatically include your news fragment in the changelog.
-
-You can read more about writing news fragments in the [Towncrier tutorial][tt].

 ## Adding compile-time [features][features]
 
-If you'd like to add a compile-time feature, you must first define it in
-the `main` workspace crate located in `src/main/Cargo.toml`. The feature must
-enable a feature in the other workspace crate(s) you intend to use it in. Then
-the said workspace crate(s) must define the feature there in its `Cargo.toml`.

+a feature in the other workspace crate(s) you intend to use it in. Then the said
+workspace crate(s) must define the feature there in its `Cargo.toml`.
 
-So, if this is adding a feature to the API such as `woof`, you define the feature
-in the `api` crate's `Cargo.toml` as `woof = []`. The feature definition in `main`'s
-`Cargo.toml` will be `woof = ["conduwuit-api/woof"]`.

+feature in the `api` crate's `Cargo.toml` as `woof = []`. The feature definition
+in `main`'s `Cargo.toml` will be `woof = ["conduwuit-api/woof"]`.
 
-The rationale for this is due to Rust / Cargo not supporting
-["workspace level features"][9], we must make a choice of; either scattering
-features all over the workspace crates, making it difficult for anyone to add
-or remove default features; or define all the features in one central workspace
-crate that propagate down/up to the other workspace crates. It is a Cargo pitfall,
-and we'd like to see better developer UX in Rust's Workspaces.

-Additionally, the definition of one single place makes "feature collection" in our
-Nix flake a million times easier instead of collecting and deduping them all from
-searching in all the workspace crates' `Cargo.toml`s. Though we wouldn't need to
-do this if Rust supported workspace-level features to begin with.

 ## Building Docker Images
 
-To build a Docker image for Continuwuity, use the standard Docker build command:
+Official Continuwuity images are built using **Docker Buildx** and the
+Dockerfile found at [`docker/Dockerfile`][dockerfile-path].
+
+The images are compatible with Docker and other container runtimes like Podman
+or containerd.
+
+The images _do not contain a shell_. They contain only the Continuwuity binary,
+required libraries, TLS certificates, and metadata.

+# Environment Variables
+
+Continuwuity can be configured entirely through environment variables, making it
+ideal for containerised deployments and infrastructure-as-code scenarios.
+
+This is a convenience reference and may not be exhaustive. The
+[Configuration Reference](./config.mdx) is the primary source for all
+configuration options.
+
+## Prefix System
+
+Continuwuity supports three environment variable prefixes for backwards
+compatibility:
+
+- `CONTINUWUITY_*` (current, recommended)
+- `CONDUWUIT_*` (compatibility)
+- `CONDUIT_*` (legacy)
+
+All three prefixes work identically. Use double underscores (`__`) to represent
+nested configuration sections from the TOML config.
+
+**Examples:**
+
+```bash
+# Simple top-level config
+CONTINUWUITY_SERVER_NAME="matrix.example.com"
+CONTINUWUITY_PORT="8008"
+
+# Nested config sections use double underscores
+# This maps to [database] section in TOML
+CONTINUWUITY_DATABASE__PATH="/var/lib/continuwuity"
+
+# This maps to [tls] section in TOML
+CONTINUWUITY_TLS__CERTS="/path/to/cert.pem"
+```
+
+## Configuration File Override
+
+You can specify a custom configuration file path:
+
+- `CONTINUWUITY_CONFIG` - Path to continuwuity.toml (current)
+- `CONDUWUIT_CONFIG` - Path to config file (compatibility)
+- `CONDUIT_CONFIG` - Path to config file (legacy)
+
