+# `gcc-riscv-docker`: a container image for compiling RISC-V 64
+
+This repository contains a `Dockerfile` which builds a container image based on `ubuntu:latest` and installs the gcc-crosscompiler for RISC-V 64. 
+
+## Usage
+
+The script is built with `podman` in mind, but should work just as well with `Docker`. To change this, adjust the comments in the files.
+
+
+```bash
+# make scripts executable
+chmod u+x build.sh
+chmod u+x compile.sh
+
+# build the container
+./build.sh
+
+# compile the file
+./compile.sh main.c -o main.o
+```
