 Web app to reduce the size of GeoJSON files.
 
+## How This Tool Reduces GeoJSON
+
+This tool reduces GeoJSON file sizes through two main techniques:
+
+### 1. Coordinate Precision Truncation
+
+Coordinates in GeoJSON files often have excessive decimal places (e.g., `1.123456789`). For most web mapping applications, 6 decimal places (~0.1 meters accuracy) is more than sufficient. This tool truncates coordinates to your specified precision, significantly reducing file size.
+
+### 2. Property Filtering
+
+GeoJSON features often contain many properties that aren't needed for display. You can select only the properties you need, removing unnecessary data.
+
 ## Developing
 
-1. Install dependencies: `bun install`
-1. Run: `bun run dev`
+1. Install dependencies: `pnpm install`
+2. Run dev server: `pnpm dev`
+3. Run tests: `pnpm test`
+4. Run checks: `pnpm check && pnpm lint`
 
 ## Building
 
 To create a production version:
 
 ```bash
-bun run build
-```
+pnpm build
+```
+
+## Testing
+
+```bash
+# Run tests once
+pnpm test
+
+# Watch mode
+pnpm test:watch
+```
