+## Reference
+
+This package was heavily inspired by [gin](https://github.com/codegangsta/gin) and [node-supervisor](https://github.com/petruisfan/node-supervisor).
+
+Basically, Gaper is a mixing of those projects above. It started from **gin** code base and I rewrote it aiming to get
+something similar to **node-supervisor** (but simpler). A big thanks for those projects and for the people behind it!
+:clap::clap:
+
+### How is Gaper different of Gin
+
+The main difference is that Gaper removes a layer of complexity from Gin which has a proxy running on top of 
+the executed server. It allows to postpone a build and reload the server when the first call hits it. With Gaper 
+we don't care about that feature, it just restarts your server whenever a change is made.
