+RPM spec files
+==============
+
+Spec files for building an RPM for ``git-pw``. These should follow the Fedora
+Python Packaging Guidelines, found `here`__.
+
+These are published on `copr`__. You can build the RPM yourself using the
+following commands:
+
+.. code-block:: bash
+
+   $ copr build $USER/$PROJECT rpm/git-pw.spec
+
+where ``$USER/$PROJECT`` refers to a project you've created on copr. If you
+haven't created one already, you can do like so:
+
+.. code-block:: bash
+
+    $ copr create $PROJECT
+
+.. note::
+
+    The source code is pulled from PyPI, thus, local builds will only reflect
+    changes to the spec file - not the source itself. If you wish to also
+    reflect these changes, you need to update the value of ``Source0`` in the
+    spec file.
+
+More information can be found in the `copr docs`__.
