+Commit Messages
+---------------
+Tags/indicators in commit messages help to determine version number bumps.
+
+  - Backwards-compatibility (BC) breaks must have commit subject lines
+    prefixed with the string "[BC BREAK] ".
+
+  - Feature commit subjects must be suffixed with " (feature)".
+
+  - Bugfix commit subjects must be suffixed with " (bugfix)".
+
+
+Versioning Scheme
+-----------------
+Use semantic versioning:
+
+  - Backwards-incompatible changes must increment the major version number;
+  - Feature additions must increment minor; and
+  - Bugfixes must increment revision.
+
+When incrementing a number, reset all that follow.
