+# Building RPMs
+
+1. Install `docker` and `docker-compose`
+2. `cd rpm`
+3. `docker-compose run rpm`
+4. Now you can run `dnf install RPMS/x84_64/darling*.rpm`
+5. `setsebool -P mmap_low_allowed 1` to allow darling low level access and run
+
+## Building on other operating systems
+
+By default, it will build for Fedora 27. To use a different OS, simply
+
+    RPM_OS=fedora:26
+
+## Future improvements
+
+- Everything is based off of dnf. Supporting zypper and yum will reach others
+- Because of the way the submodules are handled, this isn't quite ready for releasing but this can be solved using [%autosetup in the %prep to checkout the submodules.](https://fedoraproject.org/wiki/Packaging:SourceURL#Git_Submodules)
