What we need

At this point, there are 10 packages which provide enough funtionality to build an ethpm in golang. The functions defined here could even be including directly into a geth node for package management. We need contributors for the following:

• More testing and evaluate the quality of the codebase
• Open issues and send PR's for overall improvement
• Build tools that make use of this repository
• Let me know (@Hackdom on github, use the gitter link, or Hackdom#1999 if you go to Discord) if you've made a tool using this

Finish familiarizing yourself and let us know if you have any questions!

Layout

This repository abides by the standard layout as defined here

Tools

This repository uses:

• dep for dependency management
• gitflow for branch workflow

Notes

This is v0.0.1 and should be treated as such. Contributions are welcome as well as any issues identified while using this code. While some of the on-chain functionality has been lightly tested, many of the full compilation, deployment, and publishing workflows have not been fully developed nor tested just yet.
