+        The BFG is a simpler, faster alternative to git-filter-branch for
+        cleansing bad data out of your Git repository history, in particular removing
+        crazy big files and removing passwords, credentials, and other private data.
+
+        The git-filter-branch command is enormously powerful and can do things
+        that the BFG can't - but the BFG is much better for the tasks above, because
+        it's faster (10-720x), simpler (dedicated to just removing things), and
+        beautiful (can use Scala instead of bash to script customizations).
