+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `MslsMenu.php` is the WordPress bootstrap; add hooks here or split helpers into new subdirectories under `mslsmenu/` as needed.
+- `mslsmenu/` mirrors the shipping bundle; keep source and bundle in sync before release.
+- `languages/` stores translation assets; regenerate via `wp i18n make-pot` when strings move.
+- `tests/` houses Pest specs with Brain Monkey shims in `tests/Pest.php`; colocate fixtures with their specs.
+- `bin/` contains release tooling (`bin/git-release.sh`); prefer extending scripts over one-off commands.
+
+## Build, Test, and Development Commands
+- Run `composer install` after cloning to pull dev dependencies.
+- `composer test` executes the Pest suite with mocked WordPress APIs.
+- `composer analyze` runs PHPStan (level 5) against `MslsMenu.php`; keep it passing before pushing.
+- `composer coverage` enables Xdebug coverage for pull request evidence.
+- `composer build` triggers `bin/git-release.sh`, refreshing `mslsmenu/` and `mslsmenu.zip` for distribution.
+
+## Coding Style & Naming Conventions
+- Follow WordPress PHP standards: tabs for indentation, braces on new lines, no trailing commas.
+- Include `declare(strict_types=1);` in new entry points and document public APIs with PHPDoc.
+- Use `snake_case` for hook callbacks, `PascalCase` for classes, and `camelCase` for internal helpers unless a hook signature dictates otherwise.
+
+## Testing Guidelines
+- Place new specs in `tests/YourFeatureTest.php`; keep case names descriptive (`it('renders menu item')`).
+- Stub external WP functions with Brain Monkey setup blocks to keep tests deterministic.
+- Run `composer coverage` for behavioral changes and share the summary when coverage changes noticeably.
+
+## Commit & Pull Request Guidelines
+- Write short imperative subjects (≈50 chars) such as `Clean menu walker output`; batch related edits together.
+- Reference GitHub issues in the body (`Refs #123`) and list the commands you ran.
+- PRs should explain the problem, outline the fix, attach UI evidence when relevant, and confirm `composer test` plus `composer analyze`.
+
+## Release Packaging Tips
+- Bump the plugin header version in `MslsMenu.php` and sync the same value into `readme.txt` before building.
+- Run `composer build`, inspect the refreshed `mslsmenu/` contents, and spot-check the generated `mslsmenu.zip` before tagging.

-Adds the output of the Multisite Language Switcher to the one (or more) of your navigation menus(s)
+MslsMenu extends the Multisite Language Switcher by injecting a language picker into any registered WordPress navigation menu. Install it when you want users to toggle sites and languages without custom walkers.
 
-[Latest stable](https://wordpress.org/plugins/mslsmenu/)

+## Install
+- From WordPress: search for “MslsMenu” under Plugins → Add New and activate it.
+- Manual: copy the `mslsmenu/` directory to `wp-content/plugins/` and activate the plugin.
+
+## Usage
+- Head to Appearance → Menus, add the “MslsMenu” item to your chosen menu, and arrange it like any other menu entry.
+- Configure Multisite Language Switcher as usual; MslsMenu reuses its site mappings automatically.
+
+## Develop
+- `composer install` pulls dev tools (Pest, PHPStan, Brain Monkey).
+- `composer test` runs the Pest suite; `composer analyze` performs static analysis.
+
+## Contribute
+- Review `AGENTS.md` for project conventions and release steps.
+- Latest release: https://wordpress.org/plugins/mslsmenu/
