will always be matched before `abra version`.

 The cooperative cloud utility belt 🎩🐇
 
+`abra` is a command-line tool for managing your own [Co-op Cloud](https://cloud.autonomic.zone). It can provision new servers, create applications, deploy them, run backup and restore operations and a whole lot of other things. It is the go-to tool for day-to-day operations when managing a Co-op Cloud instance.
+
+## Change log
+
+See [CHANGELOG.md](./CHANGELOG.md).
+
 ## Documentation
 
 > [docs.cloud.autonomic.zone](https://docs.cloud.autonomic.zone/)
 
 ## Install
 
+Install the latest stable release:
+
 ```sh
 curl https://install.abra.autonomic.zone | bash
 ```
+
+or the bleeding-edge development version:
+
+```sh
+curl https://install.abra.autonomic.zone | bash -s -- --dev
+```
+
+The source for this script is [here](./installer/installer).
+
+## Update
+
+Run `abra upgrade` to automatically download and install the latest release
+version.
+
+To update the development version, run `abra upgrade --dev`.
+
+## Hack
+
+It's written in Bash version 4 or greater!
+
+Install it via `curl https://install.abra.autonomic.zone | bash -s -- --dev`, then you can hack on the source in `~/.abra/src`.
+
+The command-line interface is generated via [docopt](http://docopt.org/). If you add arguments then you need to run `make docopt` ro regenerate the parser.
+
+Please remember to update the [CHANGELOG](./CHANGELOG.md) when you make a change.
+
+## Release
+
+- Change the `x.x.x` header in [CHANGELOG.md](./CHANGELOG.md) to reflect new version and mark date
+- Update versions in [installer/installer](./installer/installer) and [abra](./abra)
+- `git commit` the above changes and then tag it with `git tag <your-new-version>`
+- Then `git push` and `git push --tags`
+- Deploy a new installer script `make release-installer`
+- Tell the world
