 # @rocket/cli
 
-## 0.10.1
-
-### Patch Changes
-
-- 15a82c0: Enable including script files into the simulator via `<script src=".." mdjs-use>`
-- 15a82c0: Allow only a limited set of characters for simulator includes `[a-zA-Z0-9\/\-_]`.
-  Notably, there is no:
-
-  - `:` to prevent `http://...` includes
-  - `.` so filenames as `this.is.my.js` are not supported. Also includes will be without file endings which will be added automatically
-
 ## 0.10.0

-## 0.5.4
-
-### Patch Changes
-
-- 15a82c0: Enable including script files into the simulator via `<script src=".." mdjs-use>`
-- 15a82c0: Allow only a limited set of characters for simulator includes `[a-zA-Z0-9\/\-_]`.
-  Notably, there is no:
-
-  - `:` to prevent `http://...` includes
-  - `.` so filenames as `this.is.my.js` are not supported. Also includes will be without file endings which will be added automatically
-

+# Web Menu
+
+Gathers information about your static html pages and creates menus for it.
+
+## Features
+
+- Very fast (uses wasm & html streaming for parsing)
+- Comes with multiple pre defined menus like site, breadcrumb, tableOfContents, ...
+- Menus are accessible and fully style able
+- Works with any tool that outputs html
+- Typically reduces the tools build time by offloading menu generation
+- Flexible rendering system for menus via 4 plain javascript functions (render, list, listItem, link)
+- Low dependency count
+
+## Installation
+
+```
+npm i -D @web/menu
+```
+
+## Usage
+
+```
+npx web-menu
+```
+
+## Usage as a html user
+
+Write your html as you normally would but don't include any menus.
+Where you want to place a menu put `<web-menu type="site"></web-menu>`.
+When you run `npx web-menu` it will insert the menu into this tag.
+
+e.g.
+
+You write
+
+```html
+<header>
+  <p>...</p>
+  <web-menu type="site"></web-menu>
+</header>
+```
+
+and it will become
+
+```html
+<header>
+  <p>...</p>
+  <web-menu name="site">
+    <nav aria-label="site">
+      <a href="/about/">About</a>
+      <a href="/components/" aria-current="page">Components</a>
+    </nav>
+  </web-menu>
+</header>
+```
+
+## Configuration file
+
+You can put configurations at
+
+- `config/web-menu.js`
+- `config/web-menu.mjs`
+- `web-menu.config.js`
+- `web-menu.config.mjs`
+
+```js
+export default {
+  docsDir: 'my-menu/',
+  outputDir:
+}
+```
+
+<details>
+  <summary>Types of the config file</summary>
+  <div>
+    TODO: inline types 
+  </div>
+</details>
+
+## Add your own menu type
+
+```js
+import { Menu } from '@web/menu';
+
+class MyMenu extends Menu {
+  static name = 'my-menu';
+
+  async render() {
+    return '--- My Menu ---';
+  }
+}
+
+export default {
+  docsDir: 'my-html-site/',
+  plugins: [addPlugin(MyMenu)],
+};
+```
+
+## Menu types
+
+1. **site**
+
+   - starts at level 1
+   - flat list of links
+   - commonly used as a top bar navigation of "sections"
+
+   ```html
+   <web-menu name="site">
+     <nav aria-label="site">
+       <a href="/about/">About</a>
+       <a href="/components/" aria-current="page">Components</a>
+     </nav>
+   </web-menu>
+   ```
+
+2. **index**
+
+   - starts at level 2
+   - nested ul/li list
+   - level 2 becomes a not clickable category heading if it has children
+   - level 3+ becomes a `detail/summary` element needing a click if it has children
+   - ideally used in combination with `site`
+
+   ```html
+   <web-menu name="index">
+     <nav aria-label="index">
+       <ul class="lvl-2">
+         <li class="web-menu-active">
+           <span>Content</span>
+           <ul class="lvl-3">
+             <li class="web-menu-active">
+               <details open>
+                 <summary>Accordion</summary>
+                 <ul class="lvl-4">
+                   <li class="web-menu-current">
+                     <a href="/components/content/accordion/overview/" aria-current="page"
+                       >Overview</a
+                     >
+                   </li>
+                   <li><a href="/components/content/accordion/api/">API</a></li>
+                 </ul>
+               </details>
+             </li>
+           </ul>
+         </li>
+         <li>
+           <span>Inputs</span>
+           <ul class="lvl-3">
+             <li><a href="/components/inputs/input-text/">Input Text</a></li>
+             <li><a href="/components/inputs/textarea/">Textarea</a></li>
+           </ul>
+         </li>
+       </ul>
+     </nav>
+   </web-menu>
+   ```
+
+3. **breadcrumb**
+
+   - starts at root and goes the tree up to the current page
+   - flat ol/li list
+
+   ```html
+   <web-menu name="breadcrumb">
+     <nav aria-label="Breadcrumb">
+       <ol>
+         <li class="web-menu-active"><a href="/">Home</a></li>
+         <li class="web-menu-active"><a href="/components/">Components</a></li>
+         <li class="web-menu-current">
+           <a href="/components/button-blue/" aria-current="page">Button Blue</a>
+         </li>
+       </ol>
+     </nav>
+   </web-menu>
+   ```
+
+4. **articleOverview**
+
+   - shows a flat list of pages
+   - includes multiple meta data like cover image, heading, subHeading, authors, ...
+   - typically displayed as a grid
+
+   ```html
+   <web-menu name="article-overview">
+     <div>
+       <article class="post">
+         <div class="cover">
