+
+To manage Python packages for your Viam application, you should use a virtual environment, or `venv`.
+By using a `venv`, you can install Python packages like Viam's client SDK just within the virtual environment, and not globally, which could mess with other projects or cause issues within your system.
+
+Follow this guide to set up a fresh virtual environment on your working computer and install the Python SDK as a requirement for your Viam client application.
+
+## Setup your project
+
+First, create a directory to house your project.
+For example, name your directory `viam-python`:
+
+```bash
+mkdir viam-python
+cd viam-python
+```
+
+## Create a Virtual Environment
+
+Now that you are in the project directory, create and activate a virtual environment for Python to run in.
+
+> **INFO**
+> Creating a virtual environment (`venv`) is important as it isolates this python environment from any other you might already have.
+This allows you to ensure a clean project and easier dependency management, as well as not bloating your global python environment.
+
+```bash
+python3 -m venv viam-env
+source viam-env/bin/activate
+```
+
+Now, you should see `(viam-env)` prepend the commands in your terminal window.
+This shows that the python packages being used are from this particular environment.
+
+You can exit this environment by running `deactivate`.
+
+## Install Viam
+
+Inside the activated `viam-env` python environment, you can now install the Viam SDK:
+
+```bash
+pip3 install viam-sdk
+```
+
+This will install Viam and all required dependencies.
+
+Should you need to install your own requirements, be sure to do so in this virtual environment.
+You can [make a](https://openclassrooms.com/en/courses/6900846-set-up-a-python-environment/6990546-manage-virtual-environments-using-requirements-files) <file>requirements.txt</file> and include all necessary packages within, then install the requirements for your client application using `pip install -r requirements.txt`.
+
+## Setup your IDE
+
+You'll now want to point your IDE to use the python interpreter of your new environment, rather than the default interpreter, likely the global python interpreter.
+
+The following steps are for VS Code.
+If you're not using VS Code, please read your IDE's documentation on selecting python interpreters.
+
+1. Open the `viam-python` directory in VS Code
+1. Open the Command Palette (using `⇧⌘P` or through the menus View -> Command Palette)
+1. Select the command `Python: Select Interpreter`.
+There, you should see all the interpreters available to you.
+You're looking for one the on you just made: `viam-env`.
+It will look something like: `Python 3.11.5 ('viam-env': venv) ./viam-env/bin/python`.
+If you don't see it, click the `Refresh` icon on the top right of the Command Palette.
+
+Your IDE will now recognize all packages installed in this environment.
+
+## Start building
+
+You are now ready to start using Viam's Python SDK!
