+`docker.io/volkerraschek/createrepo` and the shell script `createrepo.sh`.
+
+The primary goal of this project is to package the binary `createrepo` as
+container image to provide the functionally for CI/CD workflows or for systems
+which does contains the binary.
+
+## createrepo.sh
+
+The shell script `createrepo.sh` is a wrapper for the binary `createrepo`, which
+is not available depending on the distribution. It starts the container image
+`docker.io/volkerraschek/createrepo` in the background to call the binary. For
+this reason, a container runtime like `docker` or `podman` is necessary.
+
+### Installation
+
+The script can be installed via the following command:
+
+```bash
+curl https://git.cryptic.systems/volker.raschek/createrepo-docker/raw/branch/master/createrepo.sh --output - | sudo tee /usr/local/bin/createrepo.sh && sudo chmod +x /usr/local/bin/createrepo.sh
+```
+
+### Usage
+
+The script forwards all arguments directly to the binary running inside the
+container. For this reason, all arguments from the original binary can be used.
+
+```bash
+createrepo.sh --update .                  # Update local repository
+createrepo.sh --update /var/www/my-repo   # Update repository based on specific path
+```
