+
+Note:
+  By default, 'On Tap' will timeout at 500 miliseconds. In other words,
+  if you release a key after timeout, the key will not be generated.
+  You can increase it's value by setting the \$KEY_RELEASE_TIMEOUT environment
+  variable. This is useful in case you don't have a fast typing speed.
+
+If you want to change more keys or want a different configuration, you
+can edit the remap_keys() function inside this script.
