-	HOW DO I LOG RUNTIMES?
-	Firstly, start dreamdeamon if it isn't already running. Then select "world>Log Session" (or press the F3 key)
-	navigate the popup window to the data/logs/runtime/ folder from where your tgstation .dmb is located.
-	(you may have to make this folder yourself)
-
-	OPTIONAL: 	you can select the little checkbox down the bottom to make dreamdeamon save the log everytime you
-				start a world. Just remember to repeat these steps with a new name when you update to a new revision!
-
-	Save it with the name of the revision your server uses (e.g. r3459.txt).
-	Game Masters will now be able to grant access any runtime logs you have archived this way!
-	This will allow us to gather information on bugs across multiple servers and make maintaining the TG
-	codebase for the entire /TG/station commuity a TONNE easier :3 Thanks for your help!
