 ## Usage
 
 To check for updates, pull updated images and recreate any containers defined in the
 `docker-compose.yml` in the current directory:
 
-```
-$ fresh.phar 
-```
+    $ fresh.phar

 ## FAQ
 
 - **How does Fresh remember the last seen hash?** The container hashes are stored
   in the same directory as the `docker-compose.yml` file in a file named `fresh.yml`.
   Remove this file to force trigger an update.
+- **What are these hashes?** Fresh grabs the manifest for the image from the registry
+  and proceeds to hash a concatenation of all the various build layer hashes. This
+  should mean if the image is new but the layers are the same nothing will be updated.
