-# Astro Starter Kit: Minimal
+# radie-help
+
+Content-driven help site built with Astro and MDX.
+
+## Requirements
+
+- `node >= 22.12.0`
+- `npm`
+
+## Basic Setup
+
+1. Install dependencies:
 
 ```sh
-npm create astro@latest -- --template minimal
+npm install
 ```
 
-> 🧑‍🚀 **Seasoned astronaut?** Delete this file. Have fun!
+2. Start the local dev server:
 
-## 🚀 Project Structure
+```sh
+npm run dev
+```
 
-Inside of your Astro project, you'll see the following folders and files:
+3. Open `http://localhost:4321`.
+
+## Available Commands
+
+| Command | What it does |
+| --- | --- |
+| `npm run dev` | Start the local Astro dev server |
+| `npm run build` | Build the site for production |
+| `npm run preview` | Preview the production build locally |
+
+## How Content Works
+
+- Each top-level folder inside `src/content/` is a content section.
+- The current site includes one section: `src/content/website/`.
+- Files in a section can be `.md` or `.mdx`.
+- Each content file must include frontmatter with:
+
+```md
+---
+title: Page Title
+description: Short summary
+---
+```
+
+- `index.mdx` becomes the landing page for that section.
+  Example: `src/content/website/index.mdx` maps to `/website`
+- Any other file becomes a subpage under that section.
+  Example: `src/content/website/registration.mdx` maps to `/website/registration`
+
+## Adding A New Content Subpage
+
+To add a new page inside an existing section:
+
+1. Create a new `.md` or `.mdx` file in the relevant folder under `src/content/`.
+2. Add the required frontmatter:
+
+```md
+---
+title: New Page
+description: What this page covers
+---
+```
+
+3. Add the page body content.
+
+Example:
 
 ```text
-/
-├── public/
-├── src/
-│   └── pages/
-│       └── index.astro
-└── package.json
+src/content/website/account-recovery.mdx
 ```
 
-Astro looks for `.astro` or `.md` files in the `src/pages/` directory. Each page is exposed as a route based on its file name.
+This page will be available at:
 
-There's nothing special about `src/components/`, but that's where we like to put any Astro/React/Vue/Svelte/Preact components.
+```text
+/website/account-recovery
+```
 
-Any static assets, like images, can be placed in the `public/` directory.
+## Adding A New Content Section
 
-## 🧞 Commands
+If you want a new group of subpages, create a new folder in `src/content/` and then register it in config.
 
-All commands are run from the root of the project, from a terminal:
+### 1. Create the folder and files
 
-| Command                   | Action                                           |
-| :------------------------ | :----------------------------------------------- |
-| `npm install`             | Installs dependencies                            |
-| `npm run dev`             | Starts local dev server at `localhost:4321`      |
-| `npm run build`           | Build your production site to `./dist/`          |
-| `npm run preview`         | Preview your build locally, before deploying     |
-| `npm run astro ...`       | Run CLI commands like `astro add`, `astro check` |
-| `npm run astro -- --help` | Get help using the Astro CLI                     |
+Example:
 
-## 👀 Want to learn more?
+```text
+src/content/mobile-app/
+├── index.mdx
+└── notifications.mdx
+```
 
-Feel free to check [our documentation](https://docs.astro.build) or jump into our [Discord server](https://astro.build/chat).
+`index.mdx` should describe the section landing page. Any additional files become subpages for that section.
+
+### 2. Update `src/content.config.ts`
+
+Add a collection for the new folder and export it:
+
+```ts
+const mobileApp = defineCollection({
+  loader: glob({ base: "./src/content/mobile-app", pattern: "**/*.{md,mdx}" }),
+  schema: articleSchema,
+});
+
+export const collections = {
+  website,
+  mobileApp,
+};
+```
+
+### 3. Update `src/config/content.ts`
+
+Add the new collection name so routing and navigation include it:
+
+```ts
+export const collectionNames = ["website", "mobileApp"] as const;
+```
+
+### 4. Run the site locally
+
+```sh
+npm run dev
+```
+
+Verify that:
+
+- the new section appears on the home page
+- the section index page loads
+- the new subpages resolve under the expected URL path
+
+## Contributor Notes
+
+- Keep one topic per file.
+- Use `index.mdx` only for a section landing page.
+- Prefer lowercase, hyphenated filenames for clean URLs.
+- If you create a new top-level content folder, update both `src/content.config.ts` and `src/config/content.ts`.
