+# Add Data guide
+`Add Data` in the Kibana Home application contains a collection of tutorials for setting up data flows in the Elastic stack.
+
+Each tutorial contains 3 sets of instructions
+1. `On Premise` Instructions for setting up a data flow when both Kibana and Elastic Search are running on premise
+2. `On Premise Elastic Cloud` Instructions for setting up a data flow when Kibana is running on premise but
+Elastic Search is running on cloud.
+3. `Elastic Cloud` Instructions for setting up a data flow when both Kibana and Elastic Search are running on cloud.
+
+## Creating a new tutorial
+1. Create a new folder in the [tutorials directory](https://github.com/elastic/kibana/tree/master/src/core_plugins/kibana/server/tutorials).
+2. In the new folder, create a file called `index.js` that exports a function.
+The function must return a Javascript object that conforms to the [tutorial schema](https://github.com/elastic/kibana/blob/master/src/core_plugins/kibana/common/tutorials/tutorial_schema.js).
+3. Register the tutorial in [register.js](https://github.com/elastic/kibana/blob/master/src/core_plugins/kibana/server/tutorials/register.js) by calling `server.registerTutorial(myFuncImportedFromIndexJs)`.
+4. Add image assets to the [tutorial_resources directory](https://github.com/elastic/kibana/tree/master/src/core_plugins/kibana/public/home/tutorial_resources).
+5. Create a PR and go through the review process to get the changes approved.
+
+### Variables
+String values can contain variables that get substituted when rendered. Variables are specified by `{}`.
+For example: `{config.docs.version}` would get rendered as `6.2` when running the tutorial in Kibana 6.2.

+[Provided variables](https://github.com/elastic/kibana/blob/master/src/core_plugins/kibana/public/home/components/tutorial/replace_template_strings.js#L23)
