<summary>How to use with Pushbullet</summary>
Pushbullet is a push notification service that I found pretty easy to work with.
I logged in with my iPhone through facebook, as well as in a web browser,
grabbed the API token, and I was able to test the documentation all in just a few minutes.
### `my_pushbullet`
Replace `my_pushbullet` with whatever name you like, or leave it the same.
It's an arbitrary name for you to reference.
For example, you may have different Pushbullet configurations for different domains.
### `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`
Replace `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx` in the HTTP Access-Token header
with your API token.
You'll find this on the Pushbullet dashboard under Settings, Account, Access Tokens,
and you'll have to click to create it:
- <https://www.pushbullet.com/#settings/account>
The example was taken from the Pushbullet API documentation:
- <https://docs.pushbullet.com/#create-push>
