> [@tammasloughran](#): > > Is there any plan to create a ACCESS-NRI FAQ or troubleshooting document for common problems like this? It’s a timely question @tammasloughran. We discussed this topic at an ACCESS-NRI meeting yesterday because your topic was something that definitely needs to be captured in documentation in some way. We decided to start using the knowledge base plugin for discourse. I have created a first topic for this describing what the knowledge base is, how it works and how to contribute: > [@ACCESS-Hive Knowledge Base](https://forum.access-hive.org.au/docs?topic=417): > > About Description of the knowledge-base, and how to to add to it and improve it. Who is this for? Anyone who needs to use the knowledge-base and wants to understand how it works, in particular anyone who wants to add information to the knowledge-base, or improve the information that is already there. Introduction The knowledge base is an easy-to-find collection of important forum topics, which is displayed without clutter. The topics that are selected to be shown is defined by category an… I’d like to use this topic as a guinea pig. Can you read that guide and let me know if it is clear if you should add this topic to the knowledge base, and if so how you should go about doing so?
