+# Using the current-1.1 folder and sub-folders
+
+This folder is the top-level node that matches the [docs](../welcome.md)
+folder, but contains deltas for the .NET Core 1.1 release.
+
+The goal of this separate parallel folder structure is to provide a location
+for the 1.1 release related content that can be relatively easily merged into
+the main structure when provide version switching in the published site.
+
+The content under this node should be a smaller document set that represents
+the deltas from the Long Term Support (LTS) release and the latest
+current release. 
+
+## Structure
+
+There are two cases to adding new content for this release:
+
+* Changes to existing documents
+    - Copy the existing content into a parallel folder under this structure. Make your changes, and add the modified file to the TOC for the 1.1 preview release.
+* New documents
+    - Put the new document in the proper location, and add it to the TOC under the node for the 1.1 preview release. 
+
+All current release files should have the following added near the
+top of the topic:
+
+[!include[current release track](../includes/warning.md)]
+
+We've created a snippet to include with the following syntax:
+
+```markdown
+[!include[current release track](../includes/warning.md)]
+```
+
+### Link instructions
+
+In both cases, provide links from current release to the LTS page (or parent index.md)
+for navigational purposes.
+Consider providing links from the LTS page (or parent index.md) to the
+new current release content page.
+
+## Future Considerations
+
+Our end goal is to surface different releases as branches in the
+[docs repo](https://github.com/dotnet/docs). Until that publishing
+scenario is supported, we'll use different top-level folders for each
+current release. 
+
+When the time comes, we can merge each current release into the main
+[docs](../docs) folder, merge the TOC nodes, and publish as a separate doc
+set. We may need to merge modifications to both the LTS version of a file
+and the current release of a file, but we should be able to find those
+changes relatively easily.
