+# How to contribute
+
+The easiest way to contribute is to open an issue and start a discussion.
+Then we can decide if and how a feature or a change could be implemented and if you should submit a pull requests with code changes.
+
+Also read this first: [Being a good open source citizen](https://hackernoon.com/being-a-good-open-source-citizen-9060d0ab9732#.x3hocgw85)
+
+## General feedback and discussions
+Please start a discussion on the [core repo issue tracker](https://github.com/AutoMapper/AutoMapper/issues).
+
+## Platform
+AutoMapper is built using the RTM tooling that ships with Visual Studio 2017. This is the only configuration accepted.
+
+## Building
+
+Run `psake.cmd` from the command line. This builds and runs tests.
+
+## Bugs and feature requests?
+Please log a new issue in the appropriate GitHub repo:
+
+* [Core](https://github.com/AutoMapper/AutoMapper)
+* [EF6 Extensions](https://github.com/AutoMapper/AutoMapper.EF6)
+* [IDataReader/Record Extensions](https://github.com/AutoMapper/AutoMapper.Data)
+* [Collection Extensions](https://github.com/AutoMapper/AutoMapper.Collection)
+* [Microsoft DI Extensions](https://github.com/AutoMapper/AutoMapper.Extensions.Microsoft.DependencyInjection)
+
+## Other discussions
+https://gitter.im/AutoMapper/AutoMapper
+
+## Filing issues
+The best way to get your bug fixed is to be as detailed as you can be about the problem.
+Providing a minimal project with steps to reproduce the problem is ideal.
+Here are questions you can answer before you file a bug to make sure you're not missing any important information.
+
+1. Did you read the [documentation](https://automapper.readthedocs.io/en/latest/)?
+2. Did you include the snippet of broken code in the issue?
+3. What are the *EXACT* steps to reproduce this problem (including source/destination types, mapping configuration and execution)?
+
+GitHub supports [markdown](https://github.github.com/github-flavored-markdown/), so when filing bugs make sure you check the formatting before clicking submit.
+
+## Contributing code and content
+You will need to sign a [Contributor License Agreement](https://cla.dotnetfoundation.org/) before submitting your pull request.
+
+Make sure you can build the code. Familiarize yourself with the project workflow and our coding conventions. If you don't know what a pull request is read this article: https://help.github.com/articles/using-pull-requests.
+
+**We only accept PRs to the master branch.**
+
+Before submitting a feature or substantial code contribution please discuss it with the team and ensure it follows the product roadmap. Here's a list of blog posts that are worth reading before doing a pull request:
+
+* [Open Source Contribution Etiquette](http://tirania.org/blog/archive/2010/Dec-31.html) by Miguel de Icaza
+* [Don't "Push" Your Pull Requests](http://www.igvita.com/2011/12/19/dont-push-your-pull-requests/) by Ilya Grigorik.
+* [10 tips for better Pull Requests](http://blog.ploeh.dk/2015/01/15/10-tips-for-better-pull-requests/) by Mark Seemann
+* [How to write the perfect pull request](https://github.com/blog/1943-how-to-write-the-perfect-pull-request) by GitHub
+
+Here's a few things you should always do when making changes to the code base:
+
+**Commit/Pull Request Format**
+
+```
+Summary of the changes (Less than 80 chars)
+ - Detail 1
+ - Detail 2
+
+#bugnumber (in this specific format)
+```
+
+**Tests**
+
+-  Tests need to be provided for every bug/feature that is completed.
+-  Tests only need to be present for issues that need to be verified by QA (e.g. not tasks).
+-  If there is a scenario that is far too hard to test there does not need to be a test for it.
+  - "Too hard" is determined by the team as a whole.
