I'm really glad you're reading this, because we need volunteer developers to improve this project.
Please send a GitHub Pull Request to SwiftSpreadsheet with a clear list of what you've done (read more about pull requests).
Please follow our coding conventions (below) and make sure all of your commits are atomic (one feature per commit).
Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
$ git commit -m "A brief summary of the commit
>
> A paragraph describing what changed and its impact."
