+# Contributing Guidelines
+
+Thanks for taking the time to contribute!
+
+## Issue
+Ensure the bug was not already reported by searching on GitHub under [issues](https://github.com/NicolasConstant/sengi/issues). If you're unable to find an open issue addressing the bug, open a [new issue](https://github.com/NicolasConstant/sengi/issues/new).
+
+Please pay attention to the following points while opening an issue.
+
+### Write detailed information
+Detailed information is very helpful to understand an issue.
+
+For example:
+* How to reproduce the issue, step-by-step.
+* The expected behavior (or what is wrong).
+* Screenshots for GUI issues.
+* The operating system.
+* The browser (if any) type and version.
+* The Sengi version.
+
+
+## Pull Requests
+Pull Requests are maybe a bit early right now, since the project and code can change a lot, so it's not really adviced to open PR today. 
+I will notify explicitely when I'll be more opened to external contributions.
