+Find python executable inside your Blender installation folder. Usually is located in **C:\\Program Files\\Blender Foundation\\Blender {version}\\{version}\\python\\bin\\python.exe** (This may differ in future blender version).
+
+Open Powershell or Command Prompt as Administrator and run commands below (Example commands are for **Blender 2.83** installed to default directory).
+```bash
+# Change directory to python executable directory.
+> cd C:\Program Files\Blender Foundation\Blender 2.83\2.83\python\bin
+
+# Run pip install command.
+> python -m pip install PySide2

+Procedure may differ based on Linux distribution and blender distribution. Some Blender distributions are using system Python in that case it is required to install PySide2 using pip to system python (Not tested).
+
+**These instructions are for Blender using bundled python.**
+
+Find python executable inside your blender application.
+
+:::note Find python executable in Blender
+You can launch Blender and in "Scripting" section enter commands to console.
+```bash
+>>> import bpy
+>>> print(bpy.app.binary_path_python)
+'/path/to/python/executable'
+```
+:::
+
+Open terminal and run pip install command below.
+
+*Replace `/usr/bin/blender/2.83/python/bin/python3.7m` with your path.*
+```bash
+> /usr/bin/blender/2.83/python/bin/python3.7m -m pip install PySide2
+```
+
+:::warning No module named pip
+If you'll get error `No module named pip` you'll have to do few steps first. Open new terminal and run the python executable from Blender (entering full path).
+```bash
+# Run Python executable
+> /usr/bin/blender/2.83/python/bin/python3.7m
+# Python process should start
+>>> import ensurepip
+>>> ensurepip.bootstrap()
+```
+You can close new terminal. Run pip install command above again. Now should work as expected.
