+### Memory usage
+by using the method **set_memory_limit** you can control the max ram usage of lua, the default its 100mb
+<h5 style="color:red;">NOTE THAT EXTRA MEMORY ALOCATED OUTSIDE CALLBACKS OR EVALUATIONS  ARE CONSIDER UNPROTECTED GEHAVIOR
+AND IT WILL KILL THE APPLICATION

 ### Callbacks 
 Callbacks i'ts a way to make c functions assesible in lua code, this it's the most basic callback:
