+The easiest way is to use `DistGit source type <#distgit>`.
+
+If you need to fine tune the process and alter it somehow you can -
+Set the source type to "Custom", and use the following script::
+
+    #! /bin/sh -x
+    git clone <git url> <project name>
+    cd <project name>
+    spectool -g <spec file>
+    rpmautospec process-distgit <spec file> <spec file>
+
+Set the Buildroot dependencies to "git rpmdevtools rpmautospec" and
+the Result directory to the same <project name> string used in the
+script.
