 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 apps, deploy them, run backup and restore operations and a whole lot of other things. Please see [docs.coopcloud.tech](https://docs.coopcloud.tech) for more extensive documentation.
+<a href="https://github.com/egonelbre/gophers"><img align="right" width="150" src="https://github.com/egonelbre/gophers/raw/master/.thumb/sketch/adventure/poking-fire.png"/></a>
 
-## Hacking
+`abra` is the flagship client & command-line tool for Co-op Cloud. It has been developed specifically for the purpose of making the day-to-day operations of [operators](https://docs.coopcloud.tech/operators/) and [maintainers](https://docs.coopcloud.tech/maintainers/) pleasant & convenient. It is libre software, written in [Go](https://go.dev) and maintained and extended by the community :heart:
 
-### 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
-
-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
-
-- 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 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 -v`)
-
-### Fork maintenance
-
-#### `godotenv`
-
-We maintain a fork of [godotenv](https://github.com/Autonomic-Cooperative/godotenv) for two features:
-
-1. multi-line env var support
-2. inline comment parsing
-
-You can upgrade the version here by running `go get github.com/Autonomic-Cooperative/godotenv@<commit>` where `<commit>` is the
-latest commit you want to pin to. We are aiming to migrate to YAML format for the environment configuration, so this should only
-be a temporary thing.
-
-#### `docker/client`
-
-A number of modules in [pkg/upstream](./pkg/upstream) are copy/pasta'd from the upstream [docker/docker/client](https://pkg.go.dev/github.com/docker/docker/client). We had to do this because upstream are not exposing their API as public.
+Please see [docs.coopcloud.tech/abra](https://docs.coopcloud.tech/abra) for help on install, upgrade, hacking, troubleshooting & more!

+service. All backups are placed in the ~/.abra/backups directory.
+
+A single backup file is produced for all backup paths specified for a service.
+If we have the following backup configuration:
+
+    - "backupbot.backup.path=/var/lib/foo,/var/lib/bar"
+
+And we run "abra app backup example.com app", Abra will produce a file that
+looks like:
+
+    ~/.abra/backups/example_com_app_609341138.tar.gz
+
+This file is a compressed archive which contains all backup paths. To see paths, run:
+
+    tar -tf ~/.abra/backups/example_com_app_609341138.tar.gz
+
+(Make sure to change the name of the backup file)
+
+This single file can be used to restore your app. See "abra app restore" for more.

+List errors for a deployed app.
+
+This is a best-effort implementation and an attempt to gather a number of tips
+& tricks for finding errors together into one convenient command. When an app
+is failing to deploy or having issues, it could be a lot of things.
+
+This command currently takes into account:
+
+    Is the service deployed?
+    Is the service killed by an OOM error?
+    Is the service reporting an error (like in "ps --no-trunc" output)
+    Is the service healthcheck failing? what are the healthcheck logs?
+
+Got any more ideas? Please let us know:
+
+    https://git.coopcloud.tech/coop-cloud/organising/issues/new/choose
+
+This command is best accompanied by "abra app logs <domain>" which may reveal
+further information which can help you debug the cause of an app failure via
+the logs.

+	Usage:   "Add a server to your configuration",
 	Description: `
-This command adds a new server to your configuration so that it can be managed
-by Abra. This can be useful when you already have a server provisioned and want
-to start running Abra commands against it. 
+Add a new server to your configuration so that it can be managed by Abra.
 
-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.
+Abra uses the SSH command-line to discover connection details for your server.
+It is advised to configure an entry per-host in your ~/.ssh/config for each
+server. For example:
 
-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.
+Host example.com
+  Hostname example.com
+  User exampleUser
+  Port 12345
+  IdentityFile ~/.ssh/example@somewhere
+
+Abra can then load SSH connection details from this configuratiion with:
+
+    abra server add example.com
 
 If "--local" is passed, then Abra assumes that the current local server is
 intended as the target server. This is useful when you want to have your entire
 Co-op Cloud config located on the server itself, and not on your local
 developer machine.
-
-Example:
-
-    abra server add --local
-
-Otherwise, you may specify a remote server. The <domain> argument must be a
-publicy accessible domain name which points to your server. You should have SSH
-access to this server, Abra will assume port 22 and will use your current
-system username to make an initial connection. You can use the <user> and
-<port> arguments to adjust this.
-
-Example:
-
-    abra server add --provision --traefik varia.zone glodemodem 12345
-
-Abra will construct the following SSH connection and Docker context:
-
-    ssh://globemodem@varia.zone:12345
-
-All communication between Abra and the server will use this SSH connection.
-
-In this example, Abra will run the following operations:
-
-    1. Install Docker
-		2. Initialise Swarm mode
-		3. Deploy Traefik (core web proxy)
-
-You may omit flags to avoid performing this provisioning logic.
