 Mneme augments `ExUnit.Assertions` with a set of assertions that know how to update themselves.
@@ -119,6 +119,26 @@ It's highly recommended to configure your editor to format Elixir files on-save.
 
 Note: Mneme uses [`Rewrite`](https://github.com/hrzndhrn/rewrite) to update files, which supports the [Elixir formatter](https://hexdocs.pm/mix/Mix.Tasks.Format.html) and [`FreedomFormatter`](https://github.com/marcandre/freedom_formatter).
 
+## Command line interface
+
+Auto-assertions are run with your normal tests when you run `mix test` and a terminal prompt is used whenever one needs to be updated.
+Here's what that might look like:
+
+![Screenshot of Mneme CLI](https://github.com/zachallaun/mneme/blob/main/docs/assets/images/demo_screenshot.png?raw=true)
+
+Whenever that happens, you have a few options:
+
+|Key|Action|Description|
+|-|-|-|
+|`y`|Accept|Accept the proposed change. The assertion will be re-run and should pass.|
+|`n`|Reject|Reject the proposed change and fail the test.|
+|`s`|Skip|Skip this assertion. The test will not fail, but the `mix test` process will exit with `1`.|
+|`k`|Next|If multiple patterns have been generated, cycle to the next one.|
+|`j`|Previous|If multiple patterns have been generated, cycle to the previous one.|
+
+Note that the CLI is not available when tests are run in a CI environment.
+See the [Continuous Integration](#continuous-integration) section for more info.
+
 ## Generated patterns
 
 Mneme tries to generate match patterns that are close to what you would write.
