Make a list of all the players (witnesses, lawyers, legal assistants, officials, experts, organizations, etc.) involved in the case and for each, create a player keyword. Include everybody who has authored a document or is relevant to some fact. Don’t worry if you miss some players as you can add them later, but starting with a good list will greatly speed up loading documents and evidence.
For each player complete a brief summary of their role in the case so all members of your team understand the relevance of the player — be brief.
