+# Usage
+
+For convince use a utility like Ngrok or Hookbin to expose the demo server to the internet. For example with Ngrok run the following: `ngrok http 9090` and copy the exposed url, you will need this to properly complete the setup below.
+
+Before you can use the demo application you will need to login to your telnyx portal and configure the following:
+
+1. You will need to setup an inbound and an outbound Fax Application for this demo.
+2. Create two phone numbers:
+    - One for inbound faxes, this will need to be associated with a fax application.
+    - One for outbound faxes. 
+3. You will also need to create a SIP Connection for your outbound faxes, be sure to configure it to use your webhook url.
+
+Finally you will need to fill out `config.yaml` with the IDs listed, as well as with the outbound and inbound phone numbers.
+
+```
+bundle
+bundle exec ruby main.rb --api-key=<YOUR API KEY>
+```
