 ### Getting Started
 
+Create a file `~/.canvas/credentials.ini` and add the client_id and client_secret credentials for each of your Canvas instances. You can define your default host with `is_default=true`. If no default is explicitly defined, the Canvas CLI will use the first instance in the file as the default for each of the CLI commands.
+
+**Example:**
+
+```
+[my-canvas-instance]
+client_id=myclientid
+client_secret=myclientsecret
+
+[my-dev-canvas-instance]
+client_id=devclientid
+client_secret=devclientsecret
+is_default=true
+
+[localhost]
+client_id=localclientid
+client_secret=localclientsecret
+```
+
+Next, you're ready to install canvas.
+
 `pip install canvas`
