-Right now this uses [`letsencrypt-python`](https://github.com/Daplie/node-letsencrypt-python),
-but it's built to be able to use a node-only javascript version (in progress).

-# install the python client (takes 2 minutes normally, 20 on a raspberry pi)
-git clone https://github.com/letsencrypt/letsencrypt

-**moving towards a python-free version**
-
-There are a few partially written javascript implementation, but they use `forge` instead of using node's native `crypto` and `ursa` - so their performance is outright horrific (especially on Raspberry Pi et al). For the moment it's faster to use the wrapped python version.
-
-Once the `forge` crud is gutted away it should slide right in without a problem. Ping [@coolaj86](https://coolaj86.com) if you'd like to help.

-#### How to write a backend
-
-A backend must implement (or be wrapped to implement) this API:
-
-* `fetch(hostname, cb)` will cb(err, certs) with certs from disk (or null or error)
-* `register(args, challengeCb, done)` will register and or renew a cert
-  * args = `{ domains, email, agreeTos }` MUST check that agreeTos === true
-  * challengeCb = `function (challenge, cb) { }` handle challenge as needed, call cb()
 
 This is what `args` looks like:
