+
+### Requirements
+
+- Kobuki robot
+- Raspberry Pi (minimum 3B)
+- Camera
+- power supply for Raspberry Pi
+- laptop or computer
+
+### Steps
+
+1. **Install Python and Pip**
+   - Ensure you have Python installed on your system. You can download it from [python.org](https://www.python.org/).

+2. **Clone Our Repository**
+    - Clone our repository to your local machine doing the following :
+        - Open your terminal
+        - Change the current working directory to the location where you want the cloned directory.
+        - Type `git clone https://gitlab.fdmci.hva.nl/technische-informatica-sm3/ti-projectten/rooziinuubii79.git
+  
+3. **Install the required packages**
+    - Open the terminal and navigate to the project - scr - Python - flask.
+    - Run the following command to install the required packages:
+        - `pip install -r requirements.txt`
+        -  This will install all the python packages required to run the project.
+        -  for C++, you will need to install the following packages:
+           - OpenCV
+           - mqtt-client
