-# CraftBeerPi4
+# CraftBeerPi
 
-This is the development project for CraftBeerPi4.
-It's not ready to use at the moment.
+## Intro
+
+CraftBeerPi is an open source brewing controller.
+
+## Installation
+
+CraftBeerPi is python based and will require at last python 3.7.x  
+You can run CBPi 4.x on your Laptop. It's not required to use a Raspberry Pi.
+
+Download an install Python 3.7  [https://www.python.org/downloads/](https://www.python.org/downloads/)
+
+Open a terminal window and run the following commands.
+
+```text
+sudo python3 -m pip install cbpi
+```
+
+```text
+cbpi setup
+```
+
+```text
+cbpi start
+```
+
+The server is running under http://localhost:8000 by default.

+# Development
+
+## Development Setup
+
+Custom Plugins are shipped as standard Python packages. Just create a python virtual env and add `cbpi`as dependency
+
+{% hint style="info" %}
+How to create virtual env in Python  
+[https://docs.python.org/3/tutorial/venv.html](https://docs.python.org/3/tutorial/venv.html)
+{% endhint %}
+
+### 1. Create a virtual env with CBPi
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+python3 -m pip insatll cbpi
+```
+
+### 2. Create Folder structure
+
+
+
+### 3. Add Custom Code
+
+
+
+### 4. Test the Code
+
+
+
+### 3. Build plugin
+
+
+
+### 4. Upload the plugin
+
+### Full Example
