+        - Note: Funkin's fork currently doesn't come with the necessary binaries so you'll have to rebuild Lime. See [Troubleshooting](TROUBLESHOOTING.md#lime-related-issues).
+        - One of Funkin's dependencies uses libVLC, which requires you to install some packages to be able to compile: `sudo apt install libvlc-dev libvlccore-dev libvlccore9`
     - HTML5: Compiles without any extra setup
 9. If you are targeting for native, you may need to run `lime rebuild <PLATFORM>` and `lime rebuild <PLATFORM> -debug`
 10. `lime test <PLATFORM>` to build and launch the game for your platform (for example, `lime test windows`)

+- Segmentation fault and/or crash after `source/funkin/Conductor.hx:538: Done mapping time changes: [SongTimeChange(0ms,102bpm)]` line appears
+  - Caused by using official Lime instead of Funkin's fork. Reinstalling Lime should fix it.
+    - NOTE: Make sure you do this via `hmm` (e.g `hmm reinstall -f lime`) to guarantee you get Funkin's version of Lime.
