 ## Building
 
-There does not exist a complete list of needed packages for building. From the top of my head I can say that *cmake*, *ninja*, *make*, *grub*, *rsync* and emulator (*qemu* or *bochs*) are needed.
+### Needed packages
 
-You need cmake version of atleast 2.26. If you are using cmake that is not found from PATH, you can set the CMAKE\_COMMAND environment variable to point to the correct cmake binary.
+#### apt (tested on ubuntu 22.04)
+```# apt install build-essential git ninja-build texinfo bison flex libgmp-dev libmpfr-dev libmpc-dev parted qemu-system-x86```
+
+> ***NOTE:*** You need cmake version of atleast 2.26. If you are using cmake that is not found from PATH, you can set the CMAKE\_COMMAND environment variable to point to the correct cmake binary. Or you can let build script download correct version of cmake if you don't have one.
+
+When you clone this reposity, make sure to also clone submodules. This can be done by cloning with the command ```git clone --recurse-submodules https://git.bananymous.com/bananymous/banan-os.git``` or if you have already cloned this repo, run ```git submodule init && git submodule update```.
 
 To build the toolchain for this os. You can run the following command.
 > ***NOTE:*** The following step has to be done only once. This might take a long time since we are compiling binutils and gcc.
