## Step 5 – Setup the environment to run Vitis
To configure the environment to run Vitis, run the following scripts which set up the environment to run in a specific command shell.

source /Vitis/2020.2/settings64.sh
source /opt/xilinx/xrt/setup.sh
```
*NOTE: .csh scripts are also provided but this tutorial assumes a bash shell is used.*
To specify the location of any Data-Center or Embedded platforms you have installed, set the following environment variable:
```bash
export PLATFORM_REPO_PATHS=
```
*NOTE: On some Ubuntu distributions, you must also export LIBRARY_PATH to properly set up Vitis.*
```bash
export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
```
