+## Installing PyArmNN while using ArmNN prebuilt binaries
+
+If you wish to use ArmNN prebuilt binaries from our release page, you will need to generate the PyArmNN SWIG wrappers.
+
+Again setup your environmental variables along with a virtual environment:
+
+```bash
+$ python -m venv env
+$ source env/bin/activate
+
+$ export  ARMNN_LIB=/path/to/libs
+$ export  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/libs
+$ export  ARMNN_INCLUDE=/full/path/to/armnn/include:/full/path/to/armnn/profiling/common/include
+```
+
+Then generate the SWIG wrappers:
+```bash
+$ cd armnn/python/pyarmnn/
+$ python swig_generate.py -v
+```
+
+Then install PyArmNN:
+```bash
+# From directory armnn/python/pyarmnn/
+$ pip install .
+```
+
+As above, you can verify that PyArmNN library is installed and check PyArmNN version using:
+```bash
+$ pip show pyarmnn
+```
+You can also verify it by running the following and getting output similar to below:
+```bash
+$ python -c "import pyarmnn as ann;print(ann.GetVersion())"
+'32.0.0'
+```
