## Troubleshooting
As Jan is in development mode, you might get stuck on a broken build.
To reset your installation:
1. Use the following commands to remove any dangling backend processes:
```sh
ps aux | grep nitro
```
Look for processes like "nitro" and "nitro_arm_64," and kill them one by one with:
```sh
kill -9
```
2. **Remove Jan from your Applications folder and Cache folder**
```bash
make clean
```
This will remove all build artifacts and cached files:
- Delete Jan extension from your `~/jan/extensions` folder
- Delete all `node_modules` in current folder
- Clear Application cache in `~/Library/Caches/jan`
