 This will build the release configuration under `./build/macosx-x86_64-server-release/`.
 
+## Developing
+You can use  [CLion](https://www.jetbrains.com/clion/) to develop native parts of the JetBrains Runtime and
+[IntelliJ IDEA](https://www.jetbrains.com/idea/) for the parts written in Java.
+Both require projects to be created.
+
+### CLion
+Run
+```
+$ make compile-commands
+```
+in the git root and open the resulting `build/.../compile_commands.json` file as a project.
+Then use `Tools | Compilation Database | Change Project Root` to point to git root of this repository.
+
+See also this detailed step-by-step tutorial for all platforms:
+[How to develop OpenJDK with CLion](https://blog.jetbrains.com/clion/2020/03/openjdk-with-clion/).
+
+### IDEA
+Run
+```
+$ sh ./bin/idea.sh
+```
+in the git root to generate project files (add `--help` for options). If you have multiple
+configurations (for example, `release` and `fastdebug`), supply the `--conf <conf_name>` argument.
+Then open the git root directory as a project in IDEA.
