+# Show Changes In The Compose Commit Message View
+
+When you execute `git commit`, you'll be dropped into your default editor
+and prompted to compose a commit message. By default you'll only see the
+status and names of the files involved in the commit.
+
+To also see the line-by-line-changes in this view, you'll want to commit in
+verbose mode.
+
+```bash
+$ git commit --verbose
+```
+
+You can also set verbose mode as the default by updating your `~/.gitconfig`
+file.
+
+```
+[commit]
+    verbose = true
+```
