+# movescript.lua
+A more convenient way to move a robot.
+
+## Pastebin
+[4c2AN8Jw](https://pastebin.com/4c2AN8Jw)
+
+## Module Requirements
+*None*
+
+## Instructions
+Simply run `pastebin get 4c2AN8Jw /home/lib/movescript` to install movescript to the local computer. Then you can begin writing movescripts to tell your robots how to move. For example:
+
+```
+local ms = require("movescript")
+
+local my_script = "FFURFFL"
+ms.execute(my_script)
+```
+
+The above code will make the robot move forward twice, then up once, then turn right, then move forward twice, and finally turn left.
+
+It is also possible to specify the amount of times to perform an action, by giving an integer value before the character for the movement you want. For example:
+
+```
+local my_long_script = "10D2R5B3U"
+ms.execute(my_long_script)
+```
