 # infra-rebuild
 
+infra-rebuild mirrors nixos-rebuild closely in its command-line interface, but focuses on making infrastructure deployment more convenient. It is built for infrastructure defined in a flake, where each hosts configuration is represented by a different `nixosConfiguration` in the flakes output.
+
+For building the configuration of e.g. two hosts called `web-01` and `git` one can simply run:
+
+```
+infra-rebuild build web-01 git
+```
+
+For deploying the hosts - using the switch operation - it's as simple as:
+
+```
+infra-rebuild switch web-01 git
+```
+
+Here infra-rebuild will simply run `nixos-rebuild switch` with the `target-host` option set for each host.
+Because infra-rebuild tries to be usable without any configuration, by default it queries the hosts FQDN from its `nixosConfiguration` and uses that for the target host.
+However to override aspects of the target host for specific or all hosts, infra-rebuild also accepts a `deployment_configuration.json` as configuration.
