+When committing, you can enter multi-line commit messages more easily by omitting the -m argument; you can then edit your message in your standard editor (e.g. vi).
+
+Commit messages should have at least a first line be preceded by [ttml] with a summary of the changes. Subsequent lines can be used for further detail.
