chore: bump for new RC

This is part of trying to debug:

    coop-cloud/organising#250

And also part of:

    coop-cloud/docs.coopcloud.tech#27

Where I now try to specify the same logic as `ssh -i <my-key-path>` in
the underlying connection logic. This should help with being more
explicit about what key is being used via the SSH config file.

 The Co-op Cloud utility belt 🎩🐇
 
-`abra` is a command-line tool for managing your own [Co-op Cloud](https://coopcloud.tech). 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.

Please see [docs.coopcloud.tech](https://docs.coopcloud.tech) for more extensive documentation.
 
-## Install
+## Quick install
 
-### Arch-based Linux Distros
-
-[abra (coming-soon)](https://aur.archlinux.org/packages/abra/) or for the latest version on git [abra-git](https://aur.archlinux.org/packages/abra-git/)
-
-```sh
-yay -S abra-git # or abra
+```bash
+curl https://install.abra.autonomic.zone | bash
 ```
 
-### Debian-based Linux Distros
+Or using the latest release candidate (extra experimental!):
 
-**Coming Soon**
-
-### Homebrew
-
-**Coming Soon**
-
-### Build from source
-
-```sh
-git clone https://git.coopcloud.tech/coop-cloud/abra
-cd abra
-go env -w GOPRIVATE=coopcloud.tech
-make install
+```bash
+curl https://install.abra.autonomic.zone | bash -s -- --rc
 ```
 
-The abra binary will be in `$GOPATH/bin`.
-
-## Autocompletion
-
-**bash**
-
-Copy `scripts/autocomplete/bash` into `/etc/bash_completion.d/` and rename
-it to abra.
-
-```
-sudo cp scripts/autocomplete/bash /etc/bash_completion.d/abra
-source /etc/bash_completion.d/abra
-```
-
-In development, you can source the script in your git checkout, just make sure
-to set `PROG=abra`, otherwise it'll add completion to the wrong command:
-
-```
-PROG=abra source /path/to/abra/scripts/autocomplete/bash
-```
-
-**(fi)zsh**
-
-(fi)zsh doesn't have an autocompletion folder by default but you can create one, then copy `scripts/autocomplete/zsh` into it and add a couple lines to your `~/.zshrc` or `~/.fizsh/.fizshrc`
-
-```
-sudo mkdir /etc/zsh/completion.d/
-sudo cp scripts/autocomplete/zsh /etc/zsh/completion.d/abra
-echo "PROG=abra\n_CLI_ZSH_AUTOCOMPLETE_HACK=1\nsource /etc/zsh/completion.d/abra" >> ~/.zshrc
-```
-
-(replace .zshrc with ~/.fizsh/.fizshrc if you use fizsh)
+Source for this script is in [scripts/installer/installer](./scripts/installer/installer).
 
 ## Hacking
 
-Install direnv, run `cp .envrc.sample .envrc`, then run `direnv allow` in this directory. This will set coopcloud repos as private due to [this bug.](https://git.coopcloud.tech/coop-cloud/coopcloud.tech/issues/20#issuecomment-8201). Or you can run `go env -w GOPRIVATE=coopcloud.tech` but I'm not sure how persistent this is.
+### Getting started
+
+Install [direnv](https://direnv.net), run `cp .envrc.sample .envrc`, then run `direnv allow` in this directory. This will set coopcloud repos as private due to [this bug.](https://git.coopcloud.tech/coop-cloud/coopcloud.tech/issues/20#issuecomment-8201). Or you can run `go env -w GOPRIVATE=coopcloud.tech` but I'm not sure how persistent this is.
 
 Install [Go >= 1.16](https://golang.org/doc/install) and then:
 
 - `make build` to build
 - `./abra` to run commands
 - `make test` will run tests
+- `make install` will install it to `$GOPATH/bin`
+- `go get <package>` and `go mod tidy` to add a new dependency
 
 Our [Drone CI configuration](.drone.yml) runs a number of sanity on each pushed commit. See the [Makefile](./Makefile) for more handy targets.
 
 Please use the [conventional commit format](https://www.conventionalcommits.org/en/v1.0.0/) for your commits so we can automate our change log.
 
-## Versioning
+### Versioning
 
 We use [goreleaser](https://goreleaser.com) to help us automate releases. We use [semver](https://semver.org) for versioning all releases of the tool. While we are still in the public alpha release phase, we will maintain a `0.y.z-alpha` format. Change logs are generated from our commit logs. We are still working this out and aim to refine our release praxis as we go.
 
 For developers, while using this `-alpha` format, the `y` part is the "major" version part. So, if you make breaking changes, you increment that and _not_ the `x` part. So, if you're on `0.1.0-alpha`, then you'd go to `0.1.1-alpha` for a backwards compatible change and `0.2.0-alpha` for a backwards incompatible change.
 
-## Making a new release
+### Making a new release
 
 - Change `ABRA_VERSION` to match the new tag in [`scripts`](./scripts/installer/installer) (use [semver](https://semver.org))
-- Commit that change (e.g. `git commit -m 'chore: publish next tag 0.3.1-alpha'`)
-- Make a new tag (e.g. `git tag 0.y.z-alpha`)
+- Commit that change (e.g. `git commit -m 'chore: publish next tag x.y.z-alpha'`)
+- Make a new tag (e.g. `git tag -a x.y.z-alpha`)
 - Push the new tag (e.g. `git push && git push --tags`)
 - Wait until the build finishes on [build.coopcloud.tech](https://build.coopcloud.tech/coop-cloud/abra)
 - Deploy the new installer script (e.g. `cd ./scripts/installer && make`)
-- Check the release worked, (e.g. `abra upgrade; abra version`)
+- Check the release worked, (e.g. `abra upgrade; abra -v`)

-This command adds a new server that abra will communicate with, to deploy apps.
+This command adds a new server to your configuration so that it can be managed

+
+This command can also provision your server ("--provision/-p") so that it is
+capable of hosting Co-op Cloud apps. Abra will default to expecting that you
+have a running ssh-agent and are using SSH keys to connect to your new server.
+Abra will also read your SSH config (matching "Host" as <domain>). SSH
+connection details precedence follows as such: command-line > SSH config >
+guessed defaults.
+
+If you have no SSH key configured for this host and are instead using password
+authentication, you may pass "--ssh-auth password" to have Abra ask you for the
+password. "--ask-sudo-pass" may be passed if you run your provisioning commands
+via sudo privilege escalation.
 
 If "--local" is passed, then Abra assumes that the current local server is
