 The index starts with the startvalue and is modified by stepwidth every time it finishes a loop run. if stepwidth is omitted, the step is 1. As soon as the index is greater or equal to the endvalue, no new loop runs are started.
+To iterate over all key-value pairs in a table, it is possible to use the ''pairs'' function:
+<code lua>
+for k,v in pairs(t) do
+  -- looped code
+end
+</code>
+In the looped code, the key can be used with ''k'' and the value can be used with ''v''.
