+# Building the custom kernel

+On a NIX machine:
+```bash
+nix-build '<nixpkgs/nixos>' -A config.system.build.kernel --arg configuration ./custom-kernel.nix
+```
+
+# Uploading the kernel as an artifact to Gitea
+
+1. Create a tarball of the built kernel:
+```bash
+tar -czf custom-kernel.tar.gz -C result .
+```
+
+2. Upload the tarball as an artifact to Gitea:
+```bash
+curl -X POST -H "Content-Type: application/octet-stream" \
+     -H "Authorization: token YOUR_GITEA_TOKEN" \
+     --data-binary @custom-kernel.tar.gz \
