+Thanks for considering to contribute to the Spot Project. In order to help make the process a little eaiser for everyone, please follow these steps.
+1) In order to start the merge process please open a ticket in the [Spot Jira](https://issues.apache.org/jira/projects/SPOT/issues) and take note of the Issue key *(SPOT-###)*. 
+2) Next, open a Pull-Request (PR) and reference the Issue key in the title of the PR. If you have any question or concern please feel free to add a comment in your pull request or branch and tag any of the maintainers.
+3) Now, it's time for the community to provide feedback on your commit. Getting community feedback can be hard, but start by sending a message to the Dev list; and make sure you're [subscribed](mailto:issues-subscribe@spot.incubator.apache.org) to the Dev List.
+4) At the same time, maintainers will be taking a look at your PR. The more community input you can get, in the form of comments rather than +1s, the more attention maintainers will give. 
+There are is a manual and an automatic merge process
+   * **Manual:** When a Project maintainer has given a '+1' in the comments, then you're PR has been accepted. However, it must be manually merged by a maintainer at this point. 
+   * **Automatic:** This process initiates when 3 maintainers provide a '+1'
+   * **Note:** if there are any merge conflicts you will have to come back and fix them before the process can continue.
