 ## Key Implementation Details
-This XGBoost sample code is implemented for the CPU using the Python language. The example assumes you XGBoost installed inside a conda environment, similar to what is delivered with the installation of the Intel® Distribution for Python* as part of the [Intel® AI Analytics Toolkit](https://software.intel.com/en-us/oneapi/ai-kit). It also assumes you have set up an additional XGBoost 0.81 conda environment, with details on how to do so explained within the sample and this README.
 
-## License
-Code samples are licensed under the MIT license. See
-[License.txt](https://github.com/oneapi-src/oneAPI-samples/blob/master/License.txt) for details.
+In this sample, you will use a XGBoost model and prediction using Intel optimizations upstreamed by Intel to the latest XGBoost package and the un-optimized XGBoost 0.81 for comparison.

-## Building XGBoost for CPU
+## Set Environment Variables
 
-XGBoost is ready for use once you finish the Intel® AI Analytics Toolkit installation and have run the post installation script.
+When working with the command-line interface (CLI), you should configure the oneAPI toolkits using environment variables. Set up your CLI environment by sourcing the `setvars` script every time you open a new terminal window. This practice ensures that your compiler, libraries, and tools are ready for development.
 
-You can refer to the oneAPI [main page](https://software.intel.com/en-us/oneapi) for toolkit installation and the Toolkit [Getting Started Guide for Linux](https://software.intel.com/en-us/get-started-with-intel-oneapi-linux-get-started-with-the-intel-ai-analytics-toolkit) for post-installation steps and scripts.
+## Run the `Intel® Python XGBoost Performance` Sample
+
+### On Linux*
 
 > **Note**: If you have not already done so, set up your CLI
-> environment by sourcing  the `setvars` script located in
-> the root of your oneAPI installation.
->
-> Linux Sudo: . /opt/intel/oneapi/setvars.sh
->
-> Linux User: . ~/intel/oneapi/setvars.sh
+> environment by sourcing  the `setvars` script in the root of your oneAPI installation.
 >
-> Windows: C:\Program Files(x86)\Intel\oneAPI\setvars.bat
+> Linux*:
+> - For system wide installations: `. /opt/intel/oneapi/setvars.sh`
+> - For private installations: ` . ~/intel/oneapi/setvars.sh`
+> - For non-POSIX shells, like csh, use the following command: `bash -c 'source <install-dir>/setvars.sh ; exec csh'`
 >

-### Activate conda environment With Root Access
+XGBoost is ready for use once you finish the Intel® AI Analytics Toolkit installation and have run the post installation script.
 
-Intel Python environment will be active by default. However, if you activated another environment, you can return with the following command:
+You can refer to the oneAPI [main page](https://software.intel.com/en-us/oneapi) for toolkit installation and the Toolkit [Getting Started Guide for Linux](https://software.intel.com/en-us/get-started-with-intel-oneapi-linux-get-started-with-the-intel-ai-analytics-toolkit) for post-installation steps and scripts.
+
+#### Activate Conda with Root Access
+
+By default, the AI Kit is installed in the `/opt/intel/oneapi` folder and requires root privileges to manage it. However, if you activated another environment, you can return with the following command.
 
-#### On a Linux* System
 ```
 source activate base
 ```
 
-### Activate conda environment Without Root Access (Optional)
+#### Activate Conda without Root Access (Optional)
 
-By default, the Intel® AI Analytics Toolkit is installed in the inteloneapi folder, which requires root privileges to manage it. If you would like to bypass using root access to manage your conda environment, then you can clone your desired conda environment using the following command:
+You can choose to activate Conda environment without root access. To bypass root access to manage your Conda environment, clone and activate your desired Conda environment using the following commands similar to the following.
 
-#### On a Linux* System
 ```
 conda create --name usr_intelpython --clone base
-```
-
-Then activate your conda environment with the following command:
-
-```
 source activate usr_intelpython
 ```
