 # hermit-gcc
 
-This repository contains scripts to build the cross-compiler for the Rust-based library OS [HermitCore](https://github.com/hermit-os/libhermit-rs).
+This repository contains a [`Dockerfile`] to build the GCC cross-compiler for [the Hermit Operating System].
 
-## Requirements
+[`Dockerfile`]: Dockerfile
+[the Hermit Operating System]: http://hermit-os.org
 
-The build process works currently only on **x86-based Linux** systems. The following software packets are required to build HermitCore's toolchain on a Linux system:
+## Usage
 
-* Netwide Assembler (NASM)
-* GNU Make, GNU Binutils, cmake
-* Tools and libraries to build *linux*, *binutils* and *gcc* (e.g. flex, bison, MPFR library, ISL library, GMP library, MPC library)
-* Rust
+You can use the prebuilt [hermit-toolchain] OCI image to run `x86_64-hermit-gcc`:
 
-On Debian-based systems the packets can be installed by executing:
-```
-  sudo apt-get install cmake nasm libmpfr-dev libisl-dev libmpc-dev libgmp-dev flex bison
-```
-
-Note: If issues arise during the build, try using requirements.sh to check the versions of the necessary packets and the configuration of the LD_LIBRARY_PATH (it should contain the MPFR library, GMP library and MPC library).
+[`hermit-toolchain`]: https://github.com/hermit-os/hermit-gcc/pkgs/container/hermit-toolchain
 
-## Building the HermitCore's toolchain
+```bash
+docker run ghcr.io/hermit-os/hermit-toolchain:latest x86_64-hermit-gcc -v
+```
 
-To build the toolchain just call the script as follow:
+You can also use the image interactively and mount your current directory:
 
 ```bash
-$ ./toolchain.sh x86_64-hermit /home/usr/hermit
+docker run --rm -it -v .:/mnt -w /mnt ghcr.io/hermit-os/hermit-toolchain:latest
 ```
-
-The first argument of the script specifies the target architecture, where the second argument defines the path to the installation directory.
-To create the toolchain, write access to the installation directory is required.
