+   https://github.com/serpapi/serpapi-javascript
+2. Click the **Fork** button (top-right corner)
+3. Clone your fork locally:
+
+```bash

+cd serpapi-javascript
+```

+
+### Extension installation
+
 Install the appropriate extension for your preferred editor/IDE:
 https://deno.land/manual/getting_started/setup_your_environment. The extension
 "integrates directly to the Deno CLI using the language server protocol. This
 helps ensure that the information you get about your code aligns to how that
 code will work when you try to run it under the Deno CLI."[^1]
 
-If you use VSCode, use the following settings (`.vscode/settings.json`):
-
-```json
-{
-  "deno.enablePaths": [
-    "mod.ts",
-    "version.ts",
-    "src",
-    "tests/*.ts",
