This document was previously copied to the "Extending Terraform" section (in the
terraform-website repo), and the old URL was redirected so that the copy in
/guides can no longer be reached on the website. But the old copy of the file
remained, and now it runs the risk of confusing contributors, since the copy in
terraform-website/.../docs/extend is the more up-to-date version.
* update plugin/provider to make clear this section isn't needed for regular use
* add some links and notes about getting started
* remove the mention of binaries... I 'm not sure it's needed yet
* 'Installing Terraform Providers' section
* sometimes I can't words good
* move the 'installing providers' block
* cleanup of terms
* copy that update to plugins/provider too
The intent here is just to introduce some initial docs on our recommended
way to develop plugins in the same GOPATH as Terraform itself. The
documentation in this area needs some more fundamental rework as it is
rather outdated and mis-organized, but that's outside the scope of what
this change is trying to achieve.
