+
+## Getting Started
+### Clone repository:
+```bash
+git clone https://github.com/ahamlabs/prysmlab.git
+cd prysmlab
+```
+
+## Local Development Setup
+PrysmLab is a static HTML/JS project. There is no build step or server required, but it must be served through HTTP (not opened as a raw file).
+
+### Option A - Run with VS Code Live Server (recommended)
+1. Install the Live Server extension in VS Code
+2. Open the project folder
+3. Right-click index.html
+4. Select "Open with Live Server"
+
+```bash
+http://127.0.0.1:5500/index.html
+```
+
+You should see the PrysmLab UI load, including sidebar, gallery, search bar, etc.
+
+### Option B - Run with Python's simple server
+In your terminal:
+```bash
+python -m http.server 8000
+```
+
+Then open:
+```bash
+http://localhost:8000
+```
+
+## Authentication (Optional)
+The app includes login, sign-up, and "liked" features powered by Supabase.
+
+To use your own database:
+1. Create a Supabase project
+2. Copy your Project URL and anon key
+3. Replace these values in index.html:
+```js
+const SUPABASE_URL = "https://<your-project>.supabase.co";
+const SUPABASE_ANON_KEY = "<your-anon-key>";
+```
+4. Create the necessary tables (examples: users, liked_themes)
+5. Enable RLS (row-level security) if using production mode
+
+If you only want to preview UI components, Supabase is not required.
