+### Deskfiles
 
+Deskfiles are just shell scripts at the root of a project directory that 
+adhere to the conventions above. These can be put into version control to
+formalize and ease common development tasks like running tests or doing
+local builds.
+
+For example, if we have some directory or repository called `myproject`, if
+we create `myproject/Deskfile`, we'll be able to do any of the following:
+```sh
+$ desk go /path/to/myproject/
+$ desk go /path/to/myproject/Deskfile
+myproject/ $ desk go .
+myproject/ $ desk go
+```
+
 ### Sharing deskfiles across computers
 
 Of course, the desk config directory (by default `~/.desks`) can be a symlink
