+- move mouse to look around
+- W,A,S,D/arrow keys to move forward/backwards/left/right + Q,E/PageUp,PageDown to move up/down

+  Press space again to pause time, and shift+space to rewind time.
+- 0 to reset location + time
 - =/- (equals/minus) to change the level set
 - Ctrl+C to copy SDF to clipboard, Ctrl+V to paste SDF from clipboard. On Linux

+
+## saving SDFs
+
+if you get an SDF which looks cool, you can copy it with Ctrl+C, and save it somewhere/share it with
+your friends.
+
+also a list of SDFs is stored in `scenes.txt`.
+
+## info
+
+AutoSDF can be configured by editing `settings.txt`.
+
+If AutoSDF is running slow, you should make `sdf-length` and `color-length` smaller.
+If it's running fast, and you want more interesting shapes, you should increase them.
