 The goal is to have a _single_ "repositories" file that can be synced
 across devices. Shepherd would take this file, allow for syncing repository
 configurations and bulk operations (fetch, unified log, etc).
+
+## Building
+
+1. Grab the source from [git.nixnet.services/boots/shepherd](https://git.nixnet.services/boots/shepherd).
+2. Build using `cargo build --release`
+
+## Basic Usage
+
+The help message can be displayed by running `shepherd --help`.
+
+The default path to the configuration file is `~/config/shepherd/config.toml`; however, a different location can be specified with the `--config` flag.
+
+To add a repository to shepherd:
+```
+shepherd add <name> <git-url>
+```
+
+To list out currently tracked repositories:
+```
+shepherd list
+```
+
+To clone and update all tracked repositories:
