# JeremyStarTM's optimized kernel
This repositories includes everything you need to build JeremyStarTM's custom optimized kernel, based on Clear Linux's kernel patches and various other tweaks introduced by JeremyStarTM.
## Building
To build this kernel, run this command in your terminal:
```bash
curl -sSL "https://git.staropensource.de/JeremyStarTM/kernel-optimized/raw/branch/develop/buildtool.sh" | bash
```
