The KB Articles plugin is compatible with Jetpack. It supports the Jetpack Sharing module and also the Jetpack Markdown module.
So if you're running the Jetpack plugin for WordPress, you have the option of enabling Markdown and then writing all of your KB Articles in Markdown (highly recommended).
Writing KBAs in Markdown can be very helpful, because it takes far less time and it also makes your articles more portable. For example, if you ever decide to republish articles elsewhere in the future, you can do that easily using any platform which supports Markdown — and there are many that do.
