 Simple Docker image based on CentOS 7 to build RPM packages.
 
+## How to use
+
+There are two wrapper scripts around the rpmbuild command you could use:
+
+- `/bin/rpmbuild-official`: This will simply forward your command to the official binary at `/usr/bin/rpmbuild`
+- `/bin/rpmbuil`: This is a modified wrapper to prepare the environment before calling rpmbuil
+
+The wrapper `/bin/rpmbuil` will do the following:
+
+- create `$(pwd)/dist`
+- create rpmbuild folder structure (`BUILDRPMS|SOURCES|SPECS|SRPMS`) under `$(pwd)/dist`
+- sync local patchfiles from `$(pwd)/patch` to `$(pwd)/dist/SOURCES`
+- call `/bin/rpmbuil` with the given parameters
+
