+These learning modules are for public consumption, so you must ensure that you have the rights to any content that you contribute.
+
+Write your content in Markdown. DevNet staff reviews content according to the [Cisco Style Guide](http://www-author.cisco.com/c/en/us/td/docs/general/style/guide/Latest/stylegd.html). (Link available on Cisco VPN only.)
+
+#### Publishing Requirements
+
+To create and publish a new lab, take the following steps:
+- Add a new folder under `labs`.
+- Create a JSON file with the same name as the `labs/`_folder_ name.
+- Create markdown files named 1.md, 2.md, and so on; refer to those files in the `labs/`_folder_ JSON file.
+- Ensure that the JSON file contains appropriate page titles and file references.
+- Send a pull request to get the files commited and merged to `master` by a DevNet reviewer.
+
+A DevNet reviewer then creates a release on the repository with the latest `master` and publishes through the admin interface.
+
+#### Editors
+
+You can write Markdown in a plain text editor, but there are many desktop and Web-based options that allow you to write and preview your work at the same time. We recommend Visual Studio Code [Download](https://code.visualstudio.com/) for several reasons:
+- Lightweight environment for coding (or writing Markdown)
+- Available on Mac OS, Linux or Windows
+- Github Client integration
+- Great Markdown preview features native in the editor
+- Intuitive operation and structure
+
+You can validate a JSON file by using the [online formatter and validator](https://jsonformatter.curiousconcept.com).
