+## Install Wheel Package from Pypi
+Install DPNP
+```cmd
+python -m pip install --index-url https://pypi.anaconda.org/intel/simple -extra-index-url https://pypi.org/simple dpnp
+```
+Note: DPNP 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.
+
+Set path to Performance Libraries in case of using venv or system Python:
+```cmd
+export LD_LIBRARY_PATH=<path_to_your_env>/lib
+```
+
+It is also required to set following environment variables:
+```cmd
+export OCL_ICD_FILENAMES_RESET=1
+export OCL_ICD_FILENAMES=libintelocl.so
+```
