Help me brew some coffee! ☕️

If you enjoy this project, and like what i'm doing here, consider buying me a coffee!

This project was previously labeled as "BrewKernel"

Brewkernel was a text only very simple (and messy) project i started 3 years ago. It was my first work in OSDev and i absolutely loved it. It sadly just got too messy and i myself couldn't understand my own code anymore. About a year ago i started work on BoredOS, and pushed a "working" version of it a few days ago as of writing this (Feb. 10 2026) Brewkernel has already been deprecated and will not be accepting any pull requests or fix any issues as it is now a public archive. Thanks to everyone who helped me with Brewkernel, even if it were just ideas, and intend to keep working on this for the forseeable future!
