+# Show What Is In A Stash
+
+Usually when I want to inspect anything in git, I'll use `git show` with a
+specific ref. This can even be done with stash refs.
+
+```bash
+$ git stash list
+stash@{0}: WIP on ...
+stash@{1}: Some commit on ...
+
+$ git show stash@{0}
+# ...
+```
+
+The `git-stash` command has a built-in way of showing stashes that will save
+you from having to type out the somewhat awkward `stash@{n}` ref.
+
+```bash
+$ git stash show 1
+```
+
+This will show you the `stash@{1}` ref. You can also omit a number which
+will show you the latest stash (`stash@{0}`).
+
+See `man git-stash` for more details.
