+# Amonzo Expronzo
+
+## what is??
+
+this is for chee to make spending money on their American Express card feel like spending money.
+
+i run it on a loop on my server.
+
+it goes like this:
+
+* get the amount of money in my `amex` pot from monzo
+* log onto the amex website w/ puppeteer
+	- get current available balance
+	- take that off the total available credit to get how much has probably been spent
+* if there is more spent than in the `amex`pot, top up the `amex` pot from current account
+* send an item into the monzo feed (which sends a push notification)
+
+## how to use
+
+basically don't? and if you do, leave me alone.
+
+that being said:
+
+the script `run` is how you get it started. you'll need to run it in the directory where `get-balance.js` is, because it expects it to be there and i haven't used `dirname $(readlink -f $0)`. run it in a loop. i run it every minute on a server. you'll need to set some env vars:
+
+### environment variables
+
+name | description
+------- | ---------------
+pot_id | the pot id you will be keeping your card-paying-off money in (find it via [monzo api](https://docs.monzo.com/#pots))
+access_token | your [monzo access token](http://developers.monzo.com)
+account_id | your monzo account id
+amex_user | your amex username
+amex_pass | your amex password
+available_credit | the total available credit in your amex account
+
+## disclaimer
+
+* don't rely on this
+* don't expect it to work tomorrow
+* don't @ me
+* pull requests welcome
+* actually you can @ me sorry for being defensive
