+# Kernel
+
+## Updating kernel config
+
+When updating kernel to the new version, import proper defaults with:
+
+```sh
+make kernel-olddefconfig USERNAME=rsmitty
+```
+
+If you want to update for a specific architecture only, use:
+
+```sh
+make kernel-olddefconfig USERNAME=rsmitty PLATFORM=linux/arm64
+```
+
+## Customizing the kernel
+
+Run another target to get into `menuconfig`:
+
+```sh
+make kernel-menuconfig USERNAME=rsmitty
+```
+
+## Testing
+
+- Build and push a test image with `make USERNAME=rsmitty PUSH=true kernel`
+- PR upstream (when ready) and profit
