+Copy `scripts/autocomplete/bash` into `/etc/bash_completion.d/` and rename
+it to abra.

+(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`

 ## 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.

 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
+
+- 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`)
+- 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)
+- Check the release worked, (e.g. `abra upgrade; abra version`)
+
 ## Fork maintenance
 
 We maintain a fork of [godotenv](https://github.com/Autonomic-Cooperative/godotenv) for two features:
