 Currently, merging state storage backends places a significant burden on the Terraform team.

The time and complexity of doing so prevents us from moving Terraform forward in other ways.

 #### Maintainers
 
 Maintainers are key contributors to our Open Source project. They contribute their time and expertise and we ask that the community take extra special care to be mindful of this when interacting with them.
 
-For code that has a listed maintainer or maintainers in our [CODEOWNERS](https://github.com/hashicorp/terraform/blob/master/CODEOWNERS) file, the Terraform team will highlight them for participation in PRs which relate to the area of code they maintain. The expectation is that a maintainer will review the code and work with the PR contributor before the code is merged by the Terraform team.

 There is no expectation on response time for our maintainers; they may be indisposed for prolonged periods of time. Please be patient. Discussions on when code becomes "unmaintained" will be on a case-by-case basis. 
 
-If an an unmaintained area of code interests you and you'd like to become a maintainer, you may simply make a PR against our [CODEOWNERS](https://github.com/hashicorp/terraform/blob/master/CODEOWNERS) file with your github handle attached to the approriate area. If there is a maintainer or team of maintainers for that area, please coordinate with them as necessary.

 2. Once you believe your pull request is ready to be merged you can create your pull request.
 3. When time permits Terraform's core team members will look over your contribution and either merge, or provide comments letting you know if there is anything left to do. It may take some time for us to respond. We may also have questions that we need answered about the code, either because something doesn't make sense to us or because we want to understand your thought process. We kindly ask that you do not target specific team members. 
 4. If we have requested changes, you can either make those changes or, if you disagree with the suggested changes, we can have a conversation about our reasoning and agree on a path forward. This may be a multi-step process. Our view is that pull requests are a chance to collaborate, and we welcome conversations about how to do things better. It is the contributor's responsibility to address any changes requested. While reviewers are happy to give guidance, it is unsustainable for us to perform the coding work necessary to get a PR into a mergeable state.

Merged PRs may or may not be included in the next release based on changes the Terraform teams deems as breaking or not.
