# 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
|
