+## Editor enhancements
+
+This repository includes a script to generate a `compile_commands.json` that is compatible with C language servers such as `clangd`.
+
+### Requirements
+
+- python3.8 or newer
+- gcc-arm-none-eabi
+- clangd
+
+### Usage
+
+```bash
+./gen_compile_commands.py
+```
+
+This will create a file named `compile_commands.json` in the project root, overwriting the previous copy.
