 # Indiko
 
-No that was not a typo the project's name actually is `indiko`! This is a small implementation of [IndieAuth](https://indieweb.org/How_to_set_up_web_sign-in_on_your_own_domain) running on bun with sqlite and lit web components and serving as the authentication provider for my homelab / side projects.
+No that was not a typo the project's name actually is `indiko`! This is a small implementation of [IndieAuth](https://indieweb.org/How_to_set_up_web_sign-in_on_your_own_domain) running on bun with sqlite and serving as the authentication provider for my homelab / side projects it also supports custom clients with roles over the OAuth 2.0 spec.
 
 The canonical repo for this is hosted on tangled over at [`dunkirk.sh/indiko`](https://tangled.org/@dunkirk.sh/indiko)
 
+## Quick Start
+
+### Prerequisites
+
+- [Bun](https://bun.sh) v1.0 or higher
+- A domain with HTTPS (required for WebAuthn)
+
+### Installation
+
+1. Clone the repository:
+
+```bash
+git clone https://github.com/taciturnaxolotl/indiko.git
+cd indiko
+```
+
+2. Install dependencies:
+
+```bash
+bun install
+```
+
+3. Create a `.env` file:
+
+```bash
+cp .env.example .env
+```
+
+Configure the following environment variables:
+
+```env
+ORIGIN=https://your-indiko-domain.com
+RP_ID=your-indiko-domain.com
+PORT=3000
+NODE_ENV=production
+```
+
+- `ORIGIN` - Full URL where Indiko is hosted (must match RP_ID)
+- `RP_ID` - Domain for WebAuthn (no protocol, matches ORIGIN domain)
+- `PORT` - Port to run the server on
+- `NODE_ENV` - Environment (dev/production)
+
+The database will be automatically created at `./indiko.db` on first run.
+
+4. Start the server:
+
+```bash
+# Development (with hot reload)
+bun run dev
+
+# Production
+bun run start
+```
+
+### First User Setup
+
+On first run, you'll need to create an admin user:
+
+1. Visit `https://your-indiko-domain.com/login?invite=bootstrap`
+2. Register with a passkey
+3. This first user will automatically be an admin
+
+After the first user is created, the bootstrap invite is disabled. Subsequent users must be invited by an admin.
+
+## Usage
+
+### Creating OAuth Apps
+
+1. Go to `/admin/clients`
+2. Click "Create OAuth Client"
+3. Fill in:
+
+   - **Name** - Display name for your app
+   - **Logo URL** - (Optional) URL to app logo
+   - **Description** - (Optional) Brief description
+   - **Redirect URIs** - One or more OAuth callback URLs
+   - **Available Roles** - (Optional) Define roles users can be assigned
+   - **Default Role** - (Optional) Auto-assign this role on first auth
+
+4. Save and copy the generated credentials:
+
+   - **Client ID** - Format: `ikc_xxxxxxxxxxxxxxxxxxxxx`
+   - **Client Secret** - Format: `iks_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`
+
+   > [!IMPORTANT]
+   > The client secret is only shown once! Save it securely.
+
+### Using as an IndieAuth Provider
+
+Add these tags to your website's `<head>`:
+
+```html
+<link
+  rel="authorization_endpoint"
+  href="https://your-indiko-domain.com/auth/authorize"
+/>
+<link rel="token_endpoint" href="https://your-indiko-domain.com/auth/token" />
+<link rel="me" href="https://your-indiko-domain.com/u/your-username" />
+```
+
+Now you can sign in to IndieAuth-compatible sites using `https://your-domain.com/` as your identity.
