-Clone Digilent's [[https://github.com/digilent/vivado-hierarchies|vivado-hierarchies]] repository. Since the repository uses submodules to bring in the IPs contained in Digilent's [[https://github.com/digilent/vivado-library|vivado-library]] repository, the `--recursive` flag should be used while cloning. Alternatively, after cloning, the submodules can be initialized and updated. Both of these flows are detailed below:+
  
-**Note**: //In order to clone,// [[https://git-scm.com|git]] //must be installed on the computer. There are various different applications which can be used to interact with the git tools. The options below detail the commands used in a bash shell.//+Check if vivado-library is already included in the Vivado project, if it is not, then it should be downloaded:
  
-== Option 1. Recursive Clone == +{{https://github.com/Digilent/vivado-library/archive/refs/tags/zmod/v1/2019.1-2.zip|vivado-library-zmod-v1-2019.1-2.zip}} 
-<code>git clone --recursive https://github.com/digilent/vivado-hierarchies</code>+ 
 +Those familiar with git may want to clone the hierarchies rather than download a ZIP. The dropdown below contains brief instructions.

 +<code> 
 +cd (somewhere memorable) 
 +git clone https://github.com/digilent/vivado-library -b zmod/v1/2019.1-2

 +Otherwise (if vivado-library is included in the project), use git tools to check out the branch: 
 + 
 +**Warning!** //If IP from the library are already included in the project, checking out a different branch may cause changes to them. Be careful!// 
 + 
 +Note that the "branch" selected by this command is a git tag known to work with this documentation.
