Hi @erezrokah ,
I have checked the document that you shared as a first option. I saw someone has already added a link for the second way (you can check the screenshot). I think it is not enough for you, right? Could you elaborate more on the issue?
If it is possible, I can take this issue.

Thanks @KancerEzeroglu, sorry for not being clear with the issue.
We should re-write the repo https://github.com/netlify/netlify-cms-widget-starter as a step by step guide and add it to the docs.
The guide will replace the current forking workflow that is required to create the widget.
One example for a step by step guide is https://www.netlifycms.org/docs/gatsby/.

Just to confirm, I'll enrich the current document(https://www.netlifycms.org/docs/custom-widgets/#registerwidget), with the steps mentioned in the repo read me (https://github.com/netlify/netlify-cms-widget-starter).
Is that ok?

Yes, that's great. I recommend opening a PR (could be a draft) as soon as you have something in order to get some feedback.

Let's me know if you starting working on it and I can assign the issue to you.

hi @erezrokah ,
I've started to work on it yesterday, fyi

Hi @erezrokah ,
I prepared the first iteration as a draft.
You can check it out. After your review, I can address your comments :)

Thanks @KancerEzeroglu, if you open a PR for it Netlify will generate a preview template with your version of the site. That would make it easier to review.
