sudo apt-get install gawk make build-essential util-linux \
qemu-user-static qemu-system-arm \
git p7zip-full python3 curl

git clone https://github.com/mainsail-crew/MainsailOS.git
cd MainsailOS/
make

make clean - Clean all previous build items except the source raspian image
make distclean - Clean up the source image and trigger a new download
make cleanfix - If your build fails you, sometimes, have no Permission to clean. This will chmod to 0777 to grant full access.

MainsailOS/emulation - Contains dependencies for emulation testing
MainsailOS/src/image - Will contain an Raspberry Pi OS Image and according sha1 checksum file MainsailOS/src/workspace - Created during build, and output for compiled Images

We want to give a shoutout to jottr for mentioning a naming convention problem.
In the past we used 'raspbian' at some points for names.
But this isn't technicaly true.
MainsailOS is based of Raspberry Pi OS, not raspbian.
