+## Installation
+
+If you want to install this add-on as an end-user, please [download it from the Mozilla Add-ons site](https://addons.mozilla.org/en-GB/firefox/addon/add-on-compatibility-reporter/).
+
+## Development
+
+To work on ACR, use [`jpm`](https://github.com/mozilla-jetpack/jpm). You'll need [node/npm](http://nodejs.org/) installed.
+
+```bash
+npm install -g jpm
+git clone git@github.com:mozilla/addon-compatibility-reporter.git
+```
+
+Then use `jpm run` inside your ACR folder. A new Firefox profile with ACR installed will appear.
+
+### Test against a local `addons-server`
+
+If you want to test your reports against a local `addons-server` instance and have followed [`addons-server`'s install docs](http://addons-server.readthedocs.io/en/latest/topics/install/index.html), you can change `extensions.acr.amo_host` in `about:config` to `http://olympia.dev`.
