Depends on your position. If you have role power, then set aside time to work on documentation. If you have to lead with influence, you simply just start doing and others will follow. One of the best things you can do is document and show people how you manage the knowledge base. Secondly, you have to delegate. Nobody knows everything, you have to ask for help and regular contributions. Just be up front and let people know your intention and they'd be more than willing to help. Lastly, take regular notes. For areas that you have little to no idea about but others talk about all the time in PRs, meetings, and more, you can extract that knowledge to the point of having your best shot at making the docs as correct as possible and then you can ask for a review from someone else.
