 # Installing
 
-Stable library from PyPi:
+We'd recommend using this library with Raspberry Pi OS Bookworm or later. It requires Python ≥3.7.
+
+## Full install (recommended):
+
+We've created an easy installation script that will install all pre-requisites and get you up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal
+on your Raspberry Pi desktop, as illustrated below:
+
+![Finding the terminal](http://get.pimoroni.com/resources/github-repo-terminal.png)
+
+In the new terminal window type the commands exactly as it appears below (check for typos) and follow the on-screen instructions:
+
+```bash
+git clone https://github.com/pimoroni/PROJECT_NAME-python
+cd PROJECT_NAME-python
+./install.sh
+```
+
+**Note** Libraries will be installed in the "pimoroni" virtual environment, you will need to activate it to run examples:
 
-* Just run `pip3 install PROJECT_NAME`
+```
+source ~/.virtualenvs/pimoroni/bin/activate
+```
 
-In some cases you may need to use `sudo` or install pip with: `sudo apt install python3-pip`
+## Development:
 
-Latest/development library from GitHub:
+If you want to contribute, or like living on the edge of your seat by having the latest code, you can install the development version like so:
+
+```bash
+git clone https://github.com/pimoroni/PROJECT_NAME-python
+cd PROJECT_NAME-python
+./install.sh --unstable
+```
+
+## Install stable library from PyPi and configure manually
+
+* Set up a virtual environment: `python3 -m venv --system-site-packages $HOME/.virtualenvs/pimoroni`
+* Switch to the virtual environment: `source ~/.virtualenvs/pimoroni/bin/activate`
+* Install the library: `pip install PROJECT_NAME`
+
+In some cases you may need to us `sudo` or install pip with: `sudo apt install python3-pip`.
+
+This will not make any configuration changes, so you may also need to enable:
+
+* i2c: `sudo raspi-config nonint do_i2c 0`
+* spi: `sudo raspi-config nonint do_spi 0`
+
+You can optionally run `sudo raspi-config` or the graphical Raspberry Pi Configuration UI to enable interfaces.
 
-* `git clone https://github.com/pimoroni/PROJECT_NAME-python`
-* `cd PROJECT_NAME-python`
-* `./install.sh --unstable`
+Some of the examples have additional dependencies. You can install them with:
 
+```bash
+pip install
+```
