 #### Before Submitting a Feature Request
-* **Check the [Marlin website](http://marlinfw.org/)** for tips — you might discover that the feature is already included. Most importantly, check if you're using [the latest version of Marlin](https://github.com/MarlinFirmware/Marlin/releases) and if you can get the desired behavior by changing [Marlin's config settings](http://marlinfw.org/docs/configuration/configuration.html).
