+All markdown files are part of [this repository](https://github.com/grafana/grafana). However, all images are added to the [website repository](https://github.com/grafana/website). Therefore, the process of adding images is not as straightforward. These are the steps:
 
-First you need create a feature (PR) branch of https://github.com/grafana/website so you can make change. Then add the image to the `/static/img/docs` directory. Then make a commit that adds the image.
+1. Ensure you create a feature branch within the [website repository](https://github.com/grafana/website) to make the change. This branch needs to be based on the `old-docs` branch. 
+2. Ensure the image(s) are compressed and optimised e.g. Using [tinypng](https://tinypng.com/)
+2. Add the image(s) to the `/static/img/docs` directory

-To be able to use the image you have to quit  (CTRL-C) the `make watch` command (that you run in the same directory as this README). Then simply rerun `make watch`, it will restart the docs server but now with access to your image.

+#### Running `make watch` errors out with `Warning: Task "default" not found.`
+
+Ensure that the docker image from the [website repository](https://github.com/grafana/website) is built using the `old-docs` branch.

+## LDAP Debug View
+
+> Only available in Grafana v6.4+
+
+Grafana has an LDAP debug view built-in which allows you to test your LDAP configuration directly within Grafana. At the moment of writing, only Grafana admins can use the LDAP debug view.
+ 
+Within this view, you'll be able to see which LDAP servers are currently reachable and test your current configuration.

+
+
+To use the debug view:
+
+ 1. Type the username of a user that exists within any of your LDAP server(s)
+ 2. Then, press "Run"
+ 3. If the user is found within any of your LDAP instances, the mapping information is displayed
