Hi @elreydetoda,
I’m not really the best person to reply here but since nobody else did already I’ll do my best:
The content in the “Learn” system is authored exclusively by HashiCorp’s Education team, and as far as I know there isn’t any current plan to accept direct contributions from the community because the team wants to make sure that all of the content is written in a similar writing style, fits together into a taxonomy with other content, etc.
I can pass on specific feedback to the Education team, but I expect they would prefer not to have multiple competing documented ways to achieve the same goal unless the two were clearly differentiated; the learning guides tend to be quite a bit more “opinionated” than the reference documentation.
I’ve seen lots of folks write about their experiences on their own blogs or other similar platforms. While of course such a thing will not be as prominent to the average Terraform user as a Learn guide, it all contributes to the nice assortment of different sorts of Terraform-related content available out there.
(If anyone on the HashiCorp Education team finds this and disagrees with what I’ve said above, please do feel free to chime in and correct me!)
