+# Contributing
+
+Thank you for considering making contributions to Fourth State's Plasma MVP implementation! We welcome contributions from anyone! See the [open issues](https://github.com/FourthState/plasma-mvp-sidechain/issues) for things we need help with!
+
+Contribute to design discussions and conversation by joining the #plasma-dev channel on Blockchain @ Berkeley's [public slack](https://www.berkeleyblockchain.slack.com/).
+
+## Prerequisites
+* [Golang](https://golang.org/doc/install)
+
+* [dep](https://github.com/golang/dep)
+
+## How to get started:
+
+Add this repository into your $GOPATH/src/github.com/FourthState directory:
+
+`go get "github.com/FourthState/plasma-mvp-sidechain"`
+
+To get dependencies:
+
+`dep ensure`
+
+### Forking
+
+Using `go get` on a forked repository will result in all the import paths being wrong. So instead we will add a new remote for the original repo.
+
+To create a fork and remote branch to work on:
+
+- Create a fork on github
+
+- Go to the original repo locally (ie. `$GOPATH/src/github.com/FourthState/plasma-mvp-sidechain`)
+
+- `git remote rename origin upstream`
+
+- `git remote add origin [email protected]:user/plasma-mvp-sidechain.git`
+
+`origin` : refers to fork
+
+`upstream` : refers to original repo
+
+
+Now, create a branch that is named off the feature you are trying to implement. See these [guidelines](https://nvie.com/posts/a-successful-git-branching-model/)
+
+Make your changes. Add tests and comment those changes. 
+
+If your tests pass, push to your fork and [submit a pull request](https://github.com/FourthState/plasma-mvp-rootchain/pulls) to the develop branch.
+
+
+## Proposals:
+
+If you would like to propose a protocol change, open up an issue. If the reviewers decide the proposed change is in line with the project's aim, then a writeup should also be added to the [research repository](https://github.com/FourthState/plasma-research). It is also advisable to publish the proposed change to [Eth Research](https://ethresear.ch/), so other plasma implementations can benefit from the proposed change.
