  - This will update binary IDEs and plugins, and automatically commit them
  - Source builds need a bit more effort, as they **aren't automated at the moment**:
    - Find the build of the stable release you want to target (usually different for pycharm and idea, should have three components)
-   - I find this at https://jetbrains.com/updates/updates.xml (search for `product name="`, then `fullNumber`)
+   - Build number is avaliable on JetBrains website:
+     - IDEA: https://www.jetbrains.com/idea/download/other.html
+     - PyCharm: https://www.jetbrains.com/pycharm/download/other.html
    - Update the `version` & `buildNumber` fields in source/default.nix
    - Empty the `ideaHash`, `androidHash`, `jpsHash` and `restarterHash` (only `ideaHash` and `restarterHash` changes on a regular basis) fields and try to build to get the new hashes
-   - Run `nix build .#jetbrains.(idea/pycharm)-community-src.src.src`, then `./source/build_maven.py source/idea_maven_artefacts.json result/`

+     - `nix build .#jetbrains.idea-community-src.src.src && ./source/build_maven.py source/idea_maven_artefacts.json result/` for IDEA
+     - `nix build .#jetbrains.pycharm-community-src.src.src && ./source/build_maven.py source/pycharm_maven_artefacts.json result/` for PyCharm
    - Update `source/brokenPlugins.json` (from https://plugins.jetbrains.com/files/brokenPlugins.json)
    - Do a test build
    - If it succeeds, make a PR/merge
