+  foobar: An example that doesn't exist.
+---
+
+<!--
+    Note: Delete this comment section.
+
+    Need an example that has an **alias**? See `bat`.
+    Need a Windows example using **msvc**? See `bat`.
+-->
+
+To update or switch versions, run `webi example@stable` (or `@v2`, `@beta`,
+etc).
+
+### Files
+
+These are the files / directories that are created and/or modified with this
+install:
+
+```text
+~/.config/envman/PATH.env
+~/.local/bin/foo
+~/.local/opt/foo/
+```
+
+## Cheat Sheet
+
+> `foo` doesn't exist and this text should have been replaced. It doesn't do
+> anything, but what it does is useful because it is; everybody knows it.
+
+To run foo:
+
+```sh
+foo
+```
+
+### Add Baz Highlighting
+
+To run foo with both bar and baz highlighting turned on:
+
+```sh
+foo --bar=baz
+```
