+
+### Portable
+Pion Data Channels is written in Go and extremely portable. Anywhere Golang runs, Pion Data Channels should work as well! Instead of dealing with complicated
+cross-compiling of multiple libraries, you now can run anywhere with one `go build`
+
+### Simple API
+The API is based on an io.ReadWriteCloser.
+
+### Readable
+If code comes from an RFC we try to make sure everything is commented with a link to the spec.
+This makes learning and debugging easier, this library was written to also serve as a guide for others.
+
+### Tested
+Every commit is tested via travis-ci Go provides fantastic facilities for testing, and more will be added as time goes on.
+
+### Shared libraries
+Every pion product is built using shared libraries, allowing others to review and reuse our libraries.
