How to contribute?

Hi, I've changed my **installed** version of electron-webpack to make the `customTemplateFile ` variable configurable (edited some .js files).

Now I would like to contribute, i.e. change the **forked** version of electron-webpack (edit some .ts files) and kinda build it, then create a PR.

Could you guide me through the steps for contributing?
