 ### My controller disconnects after exiting the "Change Grip/Order" Menu
 
-This can occasionally occur due to timing sensitivites when transitioning off of the "Change Grip/Order" menu. To avoid disconnections when exiting this menu, please only press A (or B) a single time and wait until the menu has fully exited. If a disconnect still occurs, you should be able to reconnect your controller and use NXBT as normal.

 Remember, each X and Y value must be 3 digits. If you want to tilt the Right Thumbstick 75% to the left, you must write it as `R_STICK@-075+000`. Another thing to keep in mind, the sum of your X and Y can be more than 100. For example, `L_STICK@+100+100` is a 45° angle.

+### Loops
+
+A simple for-loop can be used to repeat a macro block a specified number of times. The below example loops through an indented macro block 100 times.
+
+```
+LOOP 100
+    B 0.1s
+    0.1s
+```
+
+Nested loops are also supported.
+
+```
+LOOP 100
+    B 0.1s
+    0.1s
+    # Nested loop
+    LOOP 5
+        A 0.1s
+        0.1s
+```
+
+Note, a macro line starting with `#` is ignored.
