 # Binary Ninja Intermediate Language Series, Part 1: Low Level IL
 
-The Binary Ninja Intermediate Language (BNIL) is a semantic representation of the assembly language instructions for a native architecture in Binary Ninja.  BNIL is actually a family of intermediate languages that work together to provide functionality at different abstraction layers. This developer guide is intended to cover the design and structure of the different ILs with the goal of helping clarify which APIs are best for answering which types of questions or changing which types of data. 
-
-In later guides, we'll look at other ILs. This one is just focused on the Low Level Intermediate Language (LLIL), the second stage intermediate language in BNIL. 
+The Binary Ninja Intermediate Language (BNIL) is a semantic representation of the assembly language instructions for a native architecture in Binary Ninja.  BNIL is actually a family of intermediate languages that work together to provide functionality at different abstraction layers. This developer guide is intended to cover some of the mechanics of the LLIL to distinguish it from the other ILs in the BNIL family.

-First we use the global magic variable `current_function` which gives us the python object [`function.Function`](http://api.binary.ninja/function.Function.html) for whatever function is currently selected in the UI. The variable is only usable from the python console, and shouldn't be used for headless plugins. In a script you can either use the function that was passed in if you [registered your plugin](https://api.binary.ninja/binaryninja.plugin-module.html#binaryninja.plugin.PluginCommand.register_for_function) to handle functions, or you can compute the function based on [a specific address](https://api.binary.ninja/binaryninja.binaryview-module.html?highlight=get_functions_at#binaryninja.binaryview.BinaryView.get_functions_at).

 Next we get the [`lowlevelil.LowLevelILFunction`](http://api.binary.ninja/binaryninja.lowlevelil.LowLevelILFunction.html) from the `Function` class: `current_function.low_level_il`. Iterating over the `LowLevelILFunction` class provides access to the [`lowlevelil.LowLevelILBasicBlock`](http://api.binary.ninja/binaryninja.lowlevelil.LowLevelILBasicBlock.html) classes for this function. Inside the loop we can now iterate over the `LowLevelILBasicBlock` class which provides access to the individual [`lowlevelil.LowLevelILInstruction`](http://api.binary.ninja/binaryninja.lowlevelil.LowLevelILInstruction.html) classes.

 LLIL implements the most common arithmetic as well as a host of more complicated instruction which make translating from assembly much easier. Most arithmetic and logical instruction contain `left` and `right` attributes which can themselves be other IL instructions.
