Back to being the project maintainer.

Changes have been proposed by another peer via a radicle patch. To track
changes from another peer, we must first follow them, and then create
a tracking branch in our working copy. The `rad remote add` command does all
of this.

```
$ rad remote add z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk --name bob --sync --fetch
✓ Follow policy updated for z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk (bob)
✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6Mkt67…v4N1tRk..
✓ Remote bob added
✓ Remote-tracking branch bob/master created for z6Mkt67…v4N1tRk
```

The contributor's changes are now visible to us.

```
$ git branch -r
  bob/patches/3581e83ad18f5cdd806ab50fa11cfd5dd4e8ae1c

Wait! There's a mistake.  The REQUIREMENTS should be a markdown file.  Let's
quickly update the patch before incorporating the changes.  Updating it this
way will tell others about the corrections we needed before merging the
changes.

```
$ rad patch checkout 3581e83ad18f5cdd806ab50fa11cfd5dd4e8ae1c
