- Create mods/ directory for Kindred Create addon modules
- Add ztools workbench as submodule at mods/ztools
- Add silo parts database as submodule at mods/silo
- Update README with new project structure and submodule instructions
Syncing and update submodule should work, but if it doesn't then the following will reset it (+ remove all local changes):
```sh
git submodule deinit -f src/3rdParty/OndselSolver
git submodule update --init --recursive src/3rdParty/OndselSolver
```
