-### Code Style
+### Linting and Formatting
 
-Please review and follow the [code style guide](./development/code_style.md) for formatting, linting, naming conventions, and other code standards.
+It is mandatory all your changes satisfy the lints (clippy, rustc, rustdoc, etc)
+and your code is formatted via the **nightly** rustfmt (`cargo +nightly fmt`). A lot of the
+`rustfmt.toml` features depend on nightly toolchain. It would be ideal if they
+weren't nightly-exclusive features, but they currently still are. CI's rustfmt
+uses nightly.
+
+If you need to allow a lint, please make sure it's either obvious as to why
+(e.g. clippy saying redundant clone but it's actually required) or it has a
+comment saying why. Do not write inefficient code for the sake of satisfying
+lints. If a lint is wrong and provides a more inefficient solution or
+suggestion, allow the lint and mention that in a comment.

 # Continuwuity for NixOS
 
-NixOS packages Continuwuity as `matrix-continuwuity`. This package includes both the Continuwuity software and a dedicated NixOS module for configuration and deployment.
+Continuwuity can be acquired by Nix (or [Lix][lix]) from various places:
 
-## Installation methods
+* The `flake.nix` at the root of the repo
+* The `default.nix` at the root of the repo
+* From Continuwuity's binary cache
 
-You can acquire Continuwuity with Nix (or [Lix][lix]) from these sources:
+### NixOS module
 
-* Directly from Nixpkgs using the official package (`pkgs.matrix-continuwuity`)
-* The `flake.nix` at the root of the Continuwuity repo
-* The `default.nix` at the root of the Continuwuity repo
+The `flake.nix` and `default.nix` do not currently provide a NixOS module (contributions
+welcome!), so [`services.matrix-conduit`][module] from Nixpkgs can be used to configure
+Continuwuity.
 
-## NixOS module
+### Conduit NixOS Config Module and SQLite
 
-Continuwuity now has an official NixOS module that simplifies configuration and deployment. The module is available in Nixpkgs as `services.matrix-continuwuity` from NixOS 25.05.
+Beware! The [`services.matrix-conduit`][module] module defaults to SQLite as a database backend.
+Continuwuity dropped SQLite support in favor of exclusively supporting the much faster RocksDB.
+Make sure that you are using the RocksDB backend before migrating!
 
-Here's a basic example of how to use the module:
+There is a [tool to  migrate a Conduit SQLite database to
+RocksDB](https://github.com/ShadowJonathan/conduit_toolbox/).
 
-```nix
-{ config, pkgs, ... }:
-
-{
-  services.matrix-continuwuity = {
-    enable = true;
-    settings = {
-      global = {
-        server_name = "example.com";
-        # Listening on localhost by default
-        # address and port are handled automatically
-        allow_registration = false;
-        allow_encryption = true;
-        allow_federation = true;
-        trusted_servers = [ "matrix.org" ];
-      };
-    };
-  };
-}
-```
-
-### Available options
-
-The NixOS module provides these configuration options:
-
-- `enable`: Enable the Continuwuity service
-- `user`: The user to run Continuwuity as (defaults to "continuwuity")
-- `group`: The group to run Continuwuity as (defaults to "continuwuity")
-- `extraEnvironment`: Extra environment variables to pass to the Continuwuity server
-- `package`: The Continuwuity package to use
-- `settings`: The Continuwuity configuration (in TOML format)
-
-Use the `settings` option to configure Continuwuity itself. See the [example configuration file](../configuration/examples.md#example-configuration) for all available options.
+If you want to run the latest code, you should get Continuwuity from the `flake.nix`
+or `default.nix` and set [`services.matrix-conduit.package`][package]
+appropriately to use Continuwuity instead of Conduit.
 
 ### UNIX sockets
 
-The NixOS module natively supports UNIX sockets through the `global.unix_socket_path` option. When using UNIX sockets, set `global.address` to `null`:
+Due to the lack of a Continuwuity NixOS module, when using the `services.matrix-conduit` module
+a workaround like the one below is necessary to use UNIX sockets. This is because the UNIX
+socket option does not exist in Conduit, and the module forcibly sets the `address` and
+`port` config options.
 
 ```nix
-services.matrix-continuwuity = {
-  enable = true;
-  settings = {
-    global = {
-      server_name = "example.com";
-      address = null; # Must be null when using unix_socket_path
-      unix_socket_path = "/run/continuwuity/continuwuity.sock";
-      unix_socket_perms = 660; # Default permissions for the socket
-      # ...
-    };
-  };
+options.services.matrix-conduit.settings = lib.mkOption {
+  apply = old: old // (
+    if (old.global ? "unix_socket_path")
+    then { global = builtins.removeAttrs old.global [ "address" "port" ]; }
+    else {  }
+  );
 };
+
 ```
 
-The module automatically sets the correct `RestrictAddressFamilies` in the systemd service configuration to allow access to UNIX sockets.
+Additionally, the [`matrix-conduit` systemd unit][systemd-unit] in the module does not allow
+the `AF_UNIX` socket address family in their systemd unit's `RestrictAddressFamilies=` which
+disallows the namespace from accessing or creating UNIX sockets and has to be enabled like so:
 
-### RocksDB database
+```nix
+systemd.services.conduit.serviceConfig.RestrictAddressFamilies = [ "AF_UNIX" ];
+```
 
-Continuwuity exclusively uses RocksDB as its database backend. The system configures the database path automatically to `/var/lib/continuwuity/` and you cannot change it due to the service's reliance on systemd's StateDir.
-
-If you're migrating from Conduit with SQLite, use this [tool to migrate a Conduit SQLite database to RocksDB](https://github.com/ShadowJonathan/conduit_toolbox/).
+Even though those workarounds are feasible a Continuwuity NixOS configuration module, developed and
+published by the community, would be appreciated.
 
 ### jemalloc and hardened profile
 
-Continuwuity uses jemalloc by default. This may interfere with the [`hardened.nix` profile][hardened.nix] because it uses `scudo` by default. Either disable/hide `scudo` from Continuwuity or disable jemalloc like this:
+Continuwuity uses jemalloc by default. This may interfere with the [`hardened.nix` profile][hardened.nix]
+due to them using `scudo` by default. You must either disable/hide `scudo` from Continuwuity, or
+disable jemalloc like so:
 
 ```nix
-services.matrix-continuwuity = {
-  enable = true;
-  package = pkgs.matrix-continuwuity.override {
-    enableJemalloc = false;
-  };
-  # ...
-};
-```
-
-## Upgrading from Conduit
-
-If you previously used Conduit with the `services.matrix-conduit` module:
-
-1. Ensure your Conduit uses the RocksDB backend, or migrate from SQLite using the [migration tool](https://github.com/ShadowJonathan/conduit_toolbox/)
-2. Switch to the new module by changing `services.matrix-conduit` to `services.matrix-continuwuity` in your configuration
-3. Update any custom configuration to match the new module's structure
-
-## Reverse proxy configuration
-
-You'll need to set up a reverse proxy (like nginx or caddy) to expose Continuwuity to the internet. Configure your reverse proxy to forward requests to `/_matrix` on port 443 and 8448 to your Continuwuity instance.
-
-Here's an example nginx configuration:
-
-```nginx
-server {
-    listen 443 ssl;
-    listen [::]:443 ssl;
-    listen 8448 ssl;
-    listen [::]:8448 ssl;
-
-    server_name example.com;
-
-    # SSL configuration here...
-
-    location /_matrix/ {
-        proxy_pass http://127.0.0.1:6167$request_uri;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }

-# Code Style Guide
-
-This guide outlines the coding standards and best practices for Continuwuity development. These guidelines help avoid bugs and maintain code consistency, readability, and quality across the project.
-
-These guidelines apply to new code on a best-effort basis. When modifying existing code, follow existing patterns in the immediate area you're changing and then gradually improve code style when making substantial changes.
-
-## General Principles
-
-- **Clarity over cleverness**: Write code that is easy to understand and maintain
-- **Consistency**: Pragmatically follow existing patterns in the codebase, rather than adding new dependencies.
-- **Safety**: Prefer safe, explicit code over unsafe code with implicit requirements
-- **Performance**: Consider performance implications, but not at the expense of correctness or maintainability
-
-## Formatting and Linting
-
-All code must satisfy lints (clippy, rustc, rustdoc, etc) and be formatted using **nightly** rustfmt (`cargo +nightly fmt`). Many of the `rustfmt.toml` features depend on the nightly toolchain.
-
-If you need to allow a lint, ensure it's either obvious why (e.g. clippy saying redundant clone but it's actually required) or add a comment explaining the reason. Do not write inefficient code just to satisfy lints. If a lint is wrong and provides a less efficient solution, allow the lint and mention that in a comment.
-
-If making large formatting changes across unrelated files, create a separate commit so it can be added to the `.git-blame-ignore-revs` file.
-
-## Rust-Specific Guidelines
-
-### Naming Conventions
-
-Follow standard Rust naming conventions as outlined in the [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/naming.html):
-
-- Use `snake_case` for functions, variables, and modules
-- Use `PascalCase` for types, traits, and enum variants
-- Use `SCREAMING_SNAKE_CASE` for constants and statics
-- Use descriptive names that clearly indicate purpose
-
-```rs
-// Good
-fn process_user_request(user_id: &UserId) -> Result<Response, Error> { ... }
-
-const MAX_RETRY_ATTEMPTS: usize = 3;
-
-struct UserSession {
-    session_id: String,
-    created_at: SystemTime,
-}
-
-// Avoid
-fn proc_reqw(id: &str) -> Result<Resp, Err> { ... }
-```
-
-### Error Handling
-
-- Use `Result<T, E>` for operations that can fail
-- Prefer specific error types over generic ones
-- Use `?` operator for error propagation
-- Provide meaningful error messages
-- If needed, create or use an error enum.
-
-```rs
-// Good
-fn parse_server_name(input: &str) -> Result<ServerName, InvalidServerNameError> {
-    ServerName::parse(input)
-        .map_err(|_| InvalidServerNameError::new(input))
-}
-
-// Avoid
-fn parse_server_name(input: &str) -> Result<ServerName, Box<dyn Error>> {
-    Ok(ServerName::parse(input).unwrap())
-}
-```
-
-### Option Handling
-
-- Prefer explicit `Option` handling over unwrapping
-- Use combinators like `map`, `and_then`, `unwrap_or_else` when appropriate
-
-```rs
-// Good
-let display_name = user.display_name
-    .as_ref()
-    .map(|name| name.trim())
-    .filter(|name| !name.is_empty())
-    .unwrap_or(&user.localpart);
-
-// Avoid
-let display_name = if user.display_name.is_some() {
-    user.display_name.as_ref().unwrap()
-} else {
-    &user.localpart
-};
-```
-
-## Logging Guidelines
-
-### Structured Logging
-
-**Always use structured logging instead of string interpolation.** This improves log parsing, filtering, and observability.
-
-```rs
-// Good - structured parameters
-debug!(
-    room_id = %room_id,
-    user_id = %user_id,
-    event_type = ?event.event_type(),
-    "Processing room event"
-);
-
-info!(
-    server_name = %server_name,
-    response_time_ms = response_time.as_millis(),
-    "Federation request completed successfully"
-);
-
-// Avoid - string interpolation
-debug!("Processing room event for {room_id} from {user_id}");
-info!("Federation request to {server_name} took {response_time:?}");
-```
-
-### Log Levels
-
-Use appropriate log levels:
-
-- `error!`: Unrecoverable errors that affect functionality
-- `warn!`: Potentially problematic situations that don't stop execution
-- `info!`: General information about application flow
-- `debug!`: Detailed information for debugging
-- `trace!`: Very detailed information, typically only useful during development
-
-Keep in mind the frequency that the log will be reached, and the relevancy to a server operator.
-
-```rs
-// Good
-error!(
-    error = %err,
-    room_id = %room_id,
-    "Failed to send event to room"
-);
-
-warn!(
-    server_name = %server_name,
-    attempt = retry_count,
-    "Federation request failed, retrying"
-);
-
-info!(
-    user_id = %user_id,
-    "User registered successfully"
-);
-
-debug!(
-    event_id = %event_id,
-    auth_events = ?auth_event_ids,
-    "Validating event authorization"
-);
-```
-
-### Sensitive Information
-
-Never log sensitive information such as:
-- Access tokens
-- Passwords
-- Private keys
-- Personal user data (unless specifically needed for debugging)
-
-```rs
-// Good
-debug!(
-    user_id = %user_id,
-    session_id = %session_id,
-    "Processing authenticated request"
-);
-
-// Avoid
-debug!(
-    user_id = %user_id,
-    access_token = %access_token,
-    "Processing authenticated request"
-);
-```
-
-## Lock Management
-
-### Explicit Lock Scopes
-
-**Always use closure guards instead of implicitly dropped guards.** This makes lock scopes explicit and helps prevent deadlocks.
-
-Use the `WithLock` trait from `core::utils::with_lock`:
-
-```rs
-use conduwuit::utils::with_lock::WithLock;
-
-// Good - explicit closure guard
-shared_data.with_lock(|data| {
-    data.counter += 1;
-    data.last_updated = SystemTime::now();
-    // Lock is explicitly released here
-});
-
-// Avoid - implicit guard
-{
-    let mut data = shared_data.lock().unwrap();
-    data.counter += 1;
-    data.last_updated = SystemTime::now();
-    // Lock released when guard goes out of scope - less explicit
-}
-```
-
-For async contexts, use the async variant:
-
-```rs
-use conduwuit::utils::with_lock::WithLockAsync;
-
-// Good - async closure guard
-async_shared_data.with_lock(|data| {
-    data.process_async_update();
-}).await;
-```
-
-### Lock Ordering
-
-When acquiring multiple locks, always acquire them in a consistent order to prevent deadlocks:
-
-```rs
-// Good - consistent ordering (e.g., by memory address or logical hierarchy)
-let locks = [&lock_a, &lock_b, &lock_c];
-locks.sort_by_key(|lock| lock as *const _ as usize);
-
-for lock in locks {
-    lock.with_lock(|data| {
-        // Process data
-    });
-}
-
-// Avoid - inconsistent ordering that can cause deadlocks
-lock_b.with_lock(|data_b| {
-    lock_a.with_lock(|data_a| {
-        // Deadlock risk if another thread acquires in A->B order
-    });
-});
-```
-

-
-### Code Comments
-
-- Reference related documentation or parts of the specification
-- When a task has multiple ways of being acheved, explain your reasoning for your decision
-- Update comments when code changes
-
-```rs
-/// Processes a federation request with automatic retries and backoff.
-///
-/// Implements exponential backoff to handle temporary
-/// network issues and server overload gracefully.
-pub async fn send_federation_request(
-    destination: &ServerName,
-    request: FederationRequest,
-) -> Result<FederationResponse, FederationError> {
-    // Retry with exponential backoff because federation can be flaky
-    // due to network issues or temporary server overload
-    let mut retry_delay = Duration::from_millis(100);
-
-    for attempt in 1..=MAX_RETRIES {
-        match try_send_request(destination, &request).await {
-            Ok(response) => return Ok(response),
-            Err(err) if err.is_retriable() && attempt < MAX_RETRIES => {
-                warn!(
-                    destination = %destination,
-                    attempt = attempt,
-                    error = %err,
-                    retry_delay_ms = retry_delay.as_millis(),
-                    "Federation request failed, retrying"
-                );
-
-                tokio::time::sleep(retry_delay).await;
-                retry_delay *= 2; // Exponential backoff
-            }
-            Err(err) => return Err(err),
-        }
-    }
-
-    unreachable!("Loop should have returned or failed by now")
-}
-```
-
-### Async Patterns
-
-- Use `async`/`await` appropriately
-- Avoid blocking operations in async contexts
-- Consider using `tokio::task::spawn_blocking` for CPU-intensive work
-
-```rs
-// Good - non-blocking async operation
-pub async fn fetch_user_profile(
-    &self,
-    user_id: &UserId,
-) -> Result<UserProfile, Error> {
-    let profile = self.db
-        .get_user_profile(user_id)
-        .await?;
-
-    Ok(profile)
-}
-
-// Good - CPU-intensive work moved to blocking thread
-pub async fn generate_thumbnail(
-    &self,
-    image_data: Vec<u8>,
-) -> Result<Vec<u8>, Error> {
-    tokio::task::spawn_blocking(move || {
-        image::generate_thumbnail(image_data)
-    })
-    .await
-    .map_err(|_| Error::TaskJoinError)?
-}
-```
-
-## Inclusivity and Diversity Guidelines
-
-All code and documentation must be written with inclusivity and diversity in mind. This ensures our software is welcoming and accessible to all users and contributors. Follow the [Google guide on writing inclusive code and documentation](https://developers.google.com/style/inclusive-documentation) for comprehensive guidance.
-
-The following types of language are explicitly forbidden in all code, comments, documentation, and commit messages:
-
-**Ableist language:** Avoid terms like "sanity check", "crazy", "insane", "cripple", or "blind to". Use alternatives like "validation", "unexpected", "disable", or "unaware of".
-
-**Socially-charged technical terms:** Replace overly divisive terminology with neutral alternatives:
-- "whitelist/blacklist" → "allowlist/denylist" or "permitted/blocked"
-- "master/slave" → "primary/replica", "controller/worker", or "parent/child"
-
-When working with external dependencies that use non-inclusive terminology, avoid propagating them in your own APIs and variable names.
-
-Use diverse examples in documentation that avoid culturally-specific references, assumptions about user demographics, or unnecessarily gendered language. Design with accessibility and inclusivity in mind by providing clear error messages and considering diverse user needs.
-
-This software is intended to be used by everyone regardless of background, identity, or ability. Write code and documentation that reflects this commitment to inclusivity.
