+## Adding Your Project Setup
 
 Please respect the following guidelines if you'd like to add (or link) your setup to the list.
 
 * check out the project's [code of conduct](https://github.com/stnolting/neorv32/tree/master/CODE_OF_CONDUCT.md)
 * add a link if the board you are using provides online documentation (and/or can be purchased somewhere)
 * use the :file_folder: emoji (`:file_folder:`) if the setup is located *in this* folder; use the :earth_africa: emoji (`:earth_africa:`) if it is a link to your local project
 * please add a `README` to give some brief information about the setup and a `.gitignore` to keep things clean; take a look at [`arty-a7-35-test-setup`](https://github.com/stnolting/neorv32/setups/boards/arty-a7-35-test-setup) to get some ideas what a project setup might look like
