Getting Started

You naturally would like to start by forking the repository. If you are new to git, have a look at GitHub's Fork a repo guide for instructions on how you can do this. Once you have a fork of neovim-flake you should create a branch starting at the most recent main branch. Give your branch a reasonably descriptive name, suffixed by its type - i.e feature/debugger or fix/pesky-bug.

Implement your changes and commit them to the newly created branch and when you are happy with the result and positive that it fulfills Guidelines. Once you are confident everything is in order, push the branch to GitHub and create a pull request, following the template that you will be prompted to fill.
