+# Managing tree of git repositories
+
+When managing multiple git repositories with GRM, you'll generally have a
+configuration file containing information about all the repos you have. GRM then
+makes sure that you repositories match that config. If they don't exist yet, it
+will clone them. It will also make sure that all remotes are configured properly.
+
+Let's try it out:
+
+## Get the example configuration
+
+```bash
+$ curl --proto '=https' --tlsv1.2 -sSfO https://raw.githubusercontent.com/hakoerber/git-repo-manager/master/example.config.toml
+```
+
+Then, you're ready to run the first sync. This will clone all configured repositories
+and set up the remotes.
+
+```bash
+$ grm repo sync --config example.config.toml
+[⚙] Cloning into "/home/me/projects/git-repo-manager" from "https://code.hkoerber.de/hannes/git-repo-manager.git"
+[✔] git-repo-manager: Repository successfully cloned
+[⚙] git-repo-manager: Setting up new remote "github" to "https://github.com/hakoerber/git-repo-manager.git"
+[✔] git-repo-manager: OK
+[⚙] Cloning into "/home/me/projects/dotfiles" from "https://github.com/hakoerber/dotfiles.git"
+[✔] dotfiles: Repository successfully cloned
+[✔] dotfiles: OK
+```
+
+If you run it again, it will report no changes:
+
+```
+$ grm repo sync --config example.config.toml
+[✔] git-repo-manager: OK
+[✔] dotfiles: OK
+```
+
+### Generate your own configuration
+
+Now, if you already have a few repositories, it would be quite laborious to write
+a configuration from scratch. Luckily, GRM has a way to generate a configuration
+from an existing file tree:
+
+```bash
+$ grm repo find ~/your/project/root > config.toml
+```
+
+This will detect all repositories and remotes and write them to `config.toml`.
+
+### Show the state of your projects
+
+```bash
+$ grm repo status --config example.config.toml

+```
+
+You can also use `status` without `--config` to check the repository you're currently
+in:
+
+```
+$ cd ~/example-projects/dotfiles
+$ grm repo status
+╭──────────┬──────────┬────────┬──────────┬───────┬─────────╮
