 ## Rules
 
-- For C++ includes, do not try to add absolute paths. They have to be resolved by the build system.
 - Use smart pointers in C++.
 - Use modern C++ features.
 - Attempt to reduce the amount of code rather than add more.

 > While it's possible to use [`npm`](https://github.com/npm/cli), [`yarn`](https://classic.yarnpkg.com/), or [`pnpm`](https://pnpm.io), the tooling is built around [`bun`](https://bun.sh), so you'll have an easier time if you use `bun` for development.
 
+If you are using a VSCode-flavored IDE and the `clangd` extension, you can use the `scripts/setup_clang_env.sh` script to set up the environment for C++ development. This will create a `compile_commands.json` file in the root directory of the project, which will allow the IDE to provide proper includes, better code completion and navigation.  After that, add the following to your `.vscode/settings.json` file:
+
+```json
+{
+    "clangd.arguments": [
+        "-log=verbose", 
+        "-pretty", 
+        "--background-index", 
+        "--compile-commands-dir=${workspaceFolder}/packages/react-native-quick-crypto/"
+    ],
+}
+```
+
 While developing, you can run the [example app](/example/) to test your changes. Any changes you make in your library's JavaScript code will be reflected in the example app without a rebuild. If you change any native code, then you'll need to rebuild the example app.
