===============================================================================

To access your keys and tokens, go to dash.cloudflare.com, go to your profile
(top right menu > My Profile), and select API Tokens on the left.

There are two sections: API Tokens, and API Keys

API Keys are used to manage anything on your Cloudflare account. API Tokens can
be configured so they can only access certain properties.

(Recommended) To create an API Token:
1. Click create token
2. Click "Use template" on the "Edit zone DNS" token template
3. Make sure the permissions are set to [Zone][DNS][Edit]
4. Add your site in the Zone resources, for example:
   [Include][Specific zone][example.com]
5. Click "Continue to summary" at the bottom of the form
6. Verify the configuration and click "Create Token"
7. Copy the token

(Not recommended) To get your Global API Key
1. Click "view" in the API Keys section.
2. Enter your passord and click "View"
2. Copy the key
