-  - Otherwise defaults to `master`
-- `token`
-  - Defaults to the job token
-- `persist-credentials`
-  - Indicates whether to embed the auth token into the git config. Allows users to script authenticated git commands.

-  - Defaults to `true`
-- `lfs`
-  - Indicates whether to download Git-LFS files

   - Lines up if we add submodule support in the future. Don't need to worry about calculating relative URLs. Just works, although needs to be persisted in each submodule git config.
   - Users opt out of persisted credentials (`persist-credentials: false`), or can script the removal themselves (`git config --unset-all http.https://github.com/.extraheader`).
 
-### Fetch
+### Fetch behavior
 
 Fetch only the SHA being built and set depth=1. This significantly reduces the fetch time for large repos.
 
 If a SHA isn't available (e.g. multi repo), then fetch only the specified ref with depth=1.
 
-Customers can run `git fetch --unshallow` to fetch all refs/commits. We will document this guidance.
+The input `fetch-depth` can be used to control the depth.
 
 Note:
-- The v1 input `fetch-depth` no longer exists. We can add this back in the future if needed.
 - Fetching a single commit is supported by Git wire protocol version 2. The git client uses protocol version 0 by default. The desired protocol version can be overridden in the git config or on the fetch command line invocation (`-c protocol.version=2`). We will override on the fetch command line, for transparency.
 - Git client version 2.18+ (released June 2018) is required for wire protocol version 2.
 
-### Checkout
+### Checkout behavior
 
 For CI, checkout will create a local ref with the upstream set. This allows users to script git as they normally would.
