 A static-analysis linter for DocBook XML files. It scans XML documentation sources and reports style and convention violations.
 
-## Requirements
+**Full documentation:** [jordikroon.github.io/docbook-cs](https://jordikroon.github.io/docbook-cs)
+
+---
+
+## Contributing
+
+### Requirements
 
 - PHP 8.5+
 - Extensions: `dom`, `libxml`, `simplexml`
 
-## Installation
+### Setup
 
 ```bash
-composer require jordikroon/docbookcs
+composer install
 ```
 
-## Usage
+### Running checks
 
 ```bash
-# Run with the default config file (docbookcs.xml in the current directory)
-vendor/bin/docbook-cs
-
-# Specify a config file
-vendor/bin/docbook-cs --config=myconfig.xml
-
-# Scan specific paths (overrides paths in config)
-vendor/bin/docbook-cs reference/ language/
-
-# Output as Checkstyle XML (useful for CI)
-vendor/bin/docbook-cs --report=checkstyle --no-colors > report.xml
-
-# Output as JSON
-vendor/bin/docbook-cs --report=json
-
-# Suppress progress output
-vendor/bin/docbook-cs --quiet
-```
-
-### Exit codes
-
-| Code | Meaning |
-|------|---------|
-| `0`  | No violations found |
-| `1`  | One or more violations found |
-| `2`  | Runtime error (bad config, unreadable file, etc.) |

-## Configuration
+# Tests

-Copy `docbookcs.xml.dist` to `docbookcs.xml` and adjust to your project:

-### `<sniffs>`
-
-Register sniffs by fully-qualified class name. Sniffs support optional `<property>` children for per-sniff configuration (see sniff documentation below).
-
-### `<paths>`
+### Writing a sniff
 
-Directories or files to scan, relative to the config file or absolute. These are used when no paths are passed on the command line.
-
-### `<exclude>`
-
-`fnmatch`-style patterns for paths to skip.
-
-### `<entities>`
-
-Entity directories and files that should be loaded before parsing. Lets the XML parser resolve DocBook entities defined outside the scanned tree (e.g. from `doc-base`).
-
-## Writing a custom sniff
-
-Implement `DocbookCS\Sniff\SniffInterface` (or extend `AbstractSniff`) and register it in your config:
