 ## Install
 
 ```sh
-curl -fsSL https://install.abra.autonomic.zone | bash
+curl https://install.abra.autonomic.zone | bash
 ```
-
-Specific releases are available via the project [release page](https://git.autonomic.zone/autonomic-cooperative/abra/releases).
-
-## Changes
-
-See [CHANGELOG.md](./CHANGELOG.md).
-
-## Hacking
-
-```sh
-git clone ssh://git@git.autonomic.zone:2222/autonomic-cooperative/abra.git
-cd abra
-make dev_install
-```
-
-See [autonomic-cooperative/installer-scripts](https://git.autonomic.zone/autonomic-cooperative/installer-scripts) for the installer script deployment. To make a release, just add an entry to [CHANGELOG.md](./CHANGELOG.md) and the [abra-installer](./script.d/abra-installer) / [swarm-installer](./script.d/swarm-installer) (following [semver](https://semver.org/) please) and then `git tag x.x.x && git push origin main --tags`. If you want the [installer-scripts](https://git.autonomic.zone/autonomic-cooperative/installer-scripts) deployment to pick that up, you'll need to change the version number in the [Makefile](https://git.autonomic.zone/autonomic-cooperative/installer-scripts/src/branch/main/Makefile) and run `make` in that repository and push the changes.
