Hi @RCheesley, thanks for your contribution!!

With this PR we could detect that actually the build process for local development and for the Nelify preview functionality was broken (reported at #131). Now it should work on both cases.

FYI, for other reasons (adding Crowdin support) we also moved the directory structure, (moving en to docs/en/), so you need to merge with develop branch and make adjustments accordingly.

For testing out the preview feature I opened #138 based on this branch, and you can check out how this page looks like at https://deploy-preview-138--decidim-documentation.netlify.app/en/develop/admin/spaces/assemblies/types

Feel free to retake that branch or check out my changes to see how to fix the deploy preview for this PR.

@andreslucena might it be easier to just create a new PR given the changes that have happened? I'm not overly confident with dealing with merge conflicts! 🙈

Yeah, they can be tricky to solve.

I've added you to the @decidim/documentation team so it's easier to work with this repository. You should have an invitation, after you accept it you should be able to retake #138 with the following commands:

git remote add upstream git@github.com:decidim/documentation.git # this can be https, depending on how you have set up git locally 
git fetch upstream
git checkout upstream/feature/processes-types
git checkout -b feature/processes-types

Let me know if that works for you!

Closing in favour of #138
