+***TODO:** Currently the script will always build the newest `master` branch (so it's not suitable for CI).*
+
+#### Prerequisites
+1. Docker installed (tested on macOS & Debian 10)
+2. ~30GB of free space
+
+#### Steps
+
+1. Build the container image *(this will build the kernel)*:  
+   `docker build -t build-img -f Dockerfile .`
+2. Create dummy container from image:  
+   `docker create --name build-cont build-img`
+3. Copy debs *(it will give you `debs` folder)*:
+   `docker cp build-cont:/build/proxmox-kernel/debs ./`
+4. Cleanup image & dummy container:  
+   `docker rmi -f build-img`
+
+Now you can [install debs like you would premade packages](../../README.md#proxmox---premade-packages-easy).
