+# Describe Current Changes And Create New Change
+
+One of the first patterns I learned with `jj` was a pair of commands to
+essentially "commit" the working copy and start a fresh, new change. So if I am
+done making some changes, I can add a description to the `(no description)`
+working copy and then start a new working copy _change_.
+
+```bash
+$ jj describe -m "Add status subcommand to show current status"
+$ jj new
+```
+
+I learned from [Steve](https://steveklabnik.com/) in the [jj
+discord](https://discord.gg/dkmfj3aGQN) that a shorthand for this pattern is to
+use the `jj commit` command directly.
+
+> When called without path arguments or `--interactive`, `jj commit` is
+> equivalent to `jj describe` followed by `jj new`.
+
+That means, instead of the above pair of commands, I could have done:
+
+```bash
+$ jj commit -m "Add status subcommand to show current status"
+```
+
+That would have had the same result in my case. However, notice the caveats
+mentioned in the quote above and check out `man jj-commit` for more details on
+that.
