-CF Local uses Docker to build and run Cloud Foundry apps locally.
-CF Local also supports downloading apps (droplets & settings) from a full CF installation.
+CF Local:
+  - Uses Docker to build and run Cloud Foundry apps locally.
+  - Supports downloading apps (droplets & settings) from a full CF installation.
+  - Supports mounting an empty (or non-existent) local directory to /home/vcap/app that recieves the staged app.
+  - Supports mounting a non-empty local directory to /home/vcap/app that replaces the staged app.
 
 App settings (currently env vars and a start command) are downloaded to or manually specified in ./local.yml.
 If no buildpack is specified during staging, the latest standard CF buildpacks are used to detect and compile your app.
 
 TODO:
  - `cf local push` - upload apps to a CF installation
- - Support for mounting a local directory in the app container to allow for faster iteration.
  - Improved support for connecting to local services via `VCAP_SERVICES`
- - Improved support for connecting to CF app services via `cf ssh` tunnel
+ - Improved support for connecting to CF services via `cf ssh` tunnel
  - Memory quotas, disk quotas, and multiple app instances
  - Support for running multiple apps in the same command
  - Support for running apps in the background
