+If you want to get the latest build from the master branch, you can use our "edge" builds feed. Here's an example of 
+installing edge dev builds with pip in a virtual environment.
 
 ```bash
-$ pip install --pre azure-cli --extra-index-url https://azureclinightly.blob.core.windows.net/packages
+$ virtualenv env
+$ . env/bin/activate
+$ pip install --pre azure-cli --extra-index-url https://azurecliprod.blob.core.windows.net/edge
 ```
 
-To upgrade your current nightly build pass the `--upgrade` option.

+the feed is frequently updated.
 
 ```bash
-$ pip install --upgrade --pre azure-cli --extra-index-url https://azureclinightly.blob.core.windows.net/packages
+$ pip install --upgrade --pre azure-cli --extra-index-url https://azurecliprod.blob.core.windows.net/edge --no-cache-dir
