 #Using Smart Formspec
 Smartfs provides 2nd generation Minetest forms to replace clunky formspec strings. Each smartfs form is a container filled with GUI elements. A number of default elements are included with smartfs, but modders can also define their own custom elements. This document describes the basic usage of the smartfs API.

 Smartfs can be used as a library or a mod.
 
 To use smartfs as a library, copy the smartfs.lua file to your mod folder and add
-    dofile(minetest.get\_modpath(minetest.get\_current\_modname()).."/smartfs.lua")
-to the top of any files that use it.
+    local smartfs = dofile(minetest.get\_modpath(minetest.get\_current\_modname()).."/smartfs.lua")
+
+to the top of your init.lua. If your mod is splitted to multiple files you can transport the library reference trough your mod namespace
+    yourmod.smartfs = dofile(minetest.get\_modpath(minetest.get\_current\_modname()).."/smartfs.lua")
 
 To use smartfs as a mod, add it to your game's mods folder or to the user mods folder and enable it.
+You need to set up a dependency for your mod to use it. The library is available in the global "smartfs" table in this case.
 
 ## Creating and showing forms
 A form is a rectangular area of the screen upon which all elements are placed. Use the smartfs.create() function to create a new form. This function takes two arguments and returns a form object.
