+# PU32 Toolchain
+[![pu32-toolchain](https://github.com/fontamsoc/pu32-toolchain/actions/workflows/release.yml/badge.svg)](https://github.com/fontamsoc/pu32-toolchain/actions/workflows/release.yml)
+
+## Getting the sources
+
+This repository uses submodules.
+We need the --recursive option to fetch the submodules automatically.
+
+	git clone --recursive https://github.com/fontamsoc/pu32-toolchain.git
+
+## Building the sources (Or [download prebuilts](https://github.com/fontamsoc/pu32-toolchain/releases/latest))
+
+	sudo ln -snf /bin/bash /bin/sh
+	PATH="${PATH}:/opt/pu32-toolchain/bin" make -f pu32-toolchain/makefile
+
+Build artifacts get generated under `pu32-toolchain-build/`
+
+## Installing Toolchain
+
+	sudo tar -xf pu32-toolchain-build/pu32-toolchain.tar.xz -C /opt/
+
+Environment `PATH` must be updated as follow `PATH="${PATH}:/opt/pu32-toolchain/bin"`
+
+## Running Linux in the simulator
+
+	pu32-elf-run --hdd buildroot-build/images/rootfs.ext4 linux-build/vmlinux root=/dev/hda earlyprintk=keep
+
+## Running Linux in GDB
+
