 # How to use our code for your own work?
 The retinotopic code consist of geometry processing, fMRI fitting, mathematics concepts. Therefore, it is relatively complicate to adopt without an explaination.  Here we provide some information for starters to begin. 
+## Step 0: Download necessary libraries and data
+Limited by the copyright, we have not included all the libraries. Data files are also excluded due to file size. To test, please download the following files:
+1. Download one of HCP subject to data/HCP32Kmat/ from https://osf.io/qwzv3/  
+ e.g. You will have data/HCP32Kmat/100610_32k_pRF_fMRI.mat
+2. Download the modified HCP template to code/resources/templates from https://osf.io/qwzv3/  
+3. Download nben-standalone.jar from github https://github.com/noahbenson/neuropythy and put into code\libraries\BensonRegister  
 
 ## Step 1: Get familar with the geometry processing package. 
 You can read the tutorials in the geometry processing package. The fundamental data structure is the mesh, which is consisted of a list a vertices and a list of faces.
