-# Project Structure
+## Project Structure
+---
 
 The core of the SoC is NanoSoC. This is an example, configurable system that is the main framework. It has many different memory-mapped regions, one of which is designed for the connection of accelerator subsystems called the expansion region.
 
 The expansion region is able to instantiate an accelerator_subsystem by default. This means that anyone using NanoSoC as a platform for accelerator experimentation will need to build an `accelerator_subsystem` rtl module.
 
+### Accelerator Subsystem
+---
 `accelerator_subsystem` can either directly contain an accelerator (or multiple) or can instantiate accelerator wrappers which in turn instantiate accelerators.
 
 This module is expected to be found in `system/src/accelerator_subsystem.v`.
 
+### Accelerator Wrapper
+---
+Accelerator wrappers are located in `wrapper/src`. These should instantiate accelerators and can use wrapper components within the `accelerator_wrapper_tech` repository to allow a conversion of valid//ready interfaces to a memory-mapped AHB interface.
+
 ## Running the simulation
+---
 
 socsim is a tool that SoC Labs have developed that allows for running of shell scripts anywhere within your project environment. The idea is these scripts can be customised to run scripts for different simulators.
