+
+This tutorial will assume that you know a bit about how SS13 plays.
+It's mostly intended to lay out the controls and their differences from SS13.
+
+Just like in any game, WASD is movement. If that does not work, the server probably broke.
+
+Clicking on things ""interacts"" in some object-defined sense with it, with your active hand.
+
+X switches hands. Z uses the item in your hand. Q drops items. T focuses chat. C opens your inventory.
+
+New to SS14: You can press ""E"" to activate objects. This functions similarly to clicking with an empty hand most of the time: opens interfaces, etc. The difference is that it works even without an empty hand. No longer do you need to drop your tools to use a computer!
+
+You can talk in OOC by prefixing the message with [ or /ooc.
+
+If you are not on a QWERTY keyboard, the keys mentioned above are bound to the physical location on your keyboard,
+not what letter they correspond to. For example on AZERTY movement is ZQSD, drop is A, W is activate in hand.
+
+If you have any feedback, questions, bug reports, etc..., do not be afraid to tell us!
+You can ask on Discord or heck, just write it in OOC, we'll catch it.
