+Satis-go is a web server for hosting and managing your [Satis Repository](https://github.com/composer/satis) for [Composer Packages](https://getcomposer.org/)
+
+Some Highlights:
+* Satis-go provides a simple user interface for managing the repositories you want to track in your Composer package repo
+* Repo generation is delegated to [Satis](https://github.com/composer/satis) so your package repository will stay up to date with composer
+* No database required: the satis config file is managed directly while still managing writes and reads safely
