+Install Wheel Package from Pypi
+==================================
+1. Install dpCtl
+```cmd
+python -m pip install --index-url https://pypi.anaconda.org/intel/simple -extra-index-url https://pypi.org/simple dpctl
+```
+Note: dpCtl wheel package is placed on Pypi, but some of its dependencies (like Intel numpy) are in Anaconda Cloud.
+That is why install command requires additional intel Pypi channel from Anaconda Cloud.
+
+2. Set path to Performance Libraries in case of using venv or system Python:
+On Linux:
+```cmd
+export LD_LIBRARY_PATH=<path_to_your_env>/lib
+```
+On Windows:
+```cmd
+set PATH=<path_to_your_env>\bin;<path_to_your_env>\Library\bin;%PATH%
+```
+
 Using dpCtl
 ===========
 dpCtl relies on DPC++ runtime. With Intel oneAPI installed you could activate it.
