+# Command Reference: `ci`
+
+```bash
+cml ci [options]
+```
+
+Prepares Git repository for CML operations (setting Git `user.name` &
+`user.email`, unshallow clone and undo CI oddities such as origin URL formatting
+and HTTP remote proxies).
+
+## Options
+
+Any [generic option](/doc/ref).
+
+## Examples
+
+Instead of wrangling with
+[unshallowing clones](https://stackoverflow.com/q/6802145) and
+`git config user.email` before being able to `git commit` or use
+[`cml pr`](/doc/ref/pr), simply run:
+
+```bash
+cml ci
+```
