 ## Development
 
-To work on the source files:
+⚠️ **CRITICAL: DO NOT EDIT `nostr-lite.js` DIRECTLY!**
+
+The `nostr-lite.js` file is **auto-generated** by the build script. All changes must be made in the build script itself.
+
+### Build Process
 
 ```bash
-# Edit individual components
-lite/core/nip46-client.js
-lite/ui/modal.js
-lite/nostr-login-lite.js
+# The main library source code is in:
+lite/build.js                    # ← Edit this file for library changes
 
-# Run bundler to create distribution
-node lite/bundler.js
+# To make changes:
+1. Edit lite/build.js             # Contains all source code
+2. cd lite && node build.js       # Regenerates nostr-lite.js
+3. Test your changes in examples/
 
-# Start dev server (from project root)
+# NEVER edit these files directly (they get overwritten):
+lite/nostr-lite.js               # ← Auto-generated, don't edit!
+
+# Separate components that can be edited:
+lite/ui/modal.js                 # Modal UI component
+themes/default/theme.css         # Default theme
+themes/dark/theme.css           # Dark theme
+```
+
+### Development Workflow
+
+```bash
+# 1. Make changes to source
+nano lite/build.js
+
+# 2. Rebuild bundle
+cd lite && node build.js
+
+# 3. Start dev server (from project root)
 python3 -m http.server 8000
 
-# Open test page
-open http://localhost:8000/examples/simple-demo.html
+# 4. Test changes
+open http://localhost:8000/examples/modal.html
