+## Usage
+Using `dfa` is very simple, just follow these simple steps:
+
+`dfa config set public_repo <repo-url>`
+
+Set the repo that contains your public data. Replacing `<repo-url>` with the location of your repo, supports both HTTPS and SSH, as well as any Git host.
+
+
+`dfa config set private_repo <repo-url>` (optional)
+
+Same as previous, but allows you to add private data from outside your main repo, presumably from a private repo. Useful for things like SSH keys, or sensetive environment variables.
+
+
+`dfa sync [--private]`
+
+Clones the repo into the local directory. Add the `--private` flag to clone the private repo as well, if configured.
+
+
+`dfa export [sections ...]`
+
+Where the magic happens! Exports the data using presets for certain data types, or can be extended using a [`Make` file](https://en.wikipedia.org/wiki/Makefile). See wiki for how to extend this, and how the presets work. You can specify `sections` to run, that run only the specific sections from the presets, and then from the make file.
