 Suggestions, contributions, criticisms are welcome. Though please make sure to familiarize yourself deeply with IPFS, the models it adopts, and the principles it follows.
 
 Please be aware that specs are really hard to design by committee. Treat this space like you would the workshop of an artist. Please suggest improvements, but please don't be disappointed if we say no to something. What we leave out is often more important than what we add in.

+Feel free to join in. All welcome. Open an [issue](https://github.com/ipfs/specs/issues)!
