 ## Setup
 
-This program was made for Linux.\
-It may work on Windows or Mac too, but it was not tested on these systems.\
-To be able to use this program, you have to clone the repository,\
-install the requirements and make the file called "main.py" executable.\
+This program was made for Linux. It may work on Windows or Mac too, but it was not tested on these systems.\
+Before you can install the editor, you first have to install the requirements. That can be done using:
+
+```bash
+sudo apt install pyqt6-dev-tools xcb libxcb-cursor0
+```
+
+And to install the editor, you just have to clone the repository and install it using pip.\
 You can do that using these commands:
 
 ```bash
 git clone https://teapot.informationsanarchistik.de/Wobbl/Bread_Editor.git
 cd Bread_Editor
-pip install -r requirements.txt
-chmod +x main.py
+pip install .
 ```
 
-Now you can execute the program using `./main.py`.
-You can also create a desktop shortcut to the file.
\ No newline at end of file
+If you have already set up git for ssh, you can also clone the repository like this:
+
+```bash
+git clone git git@teapot.informationsanarchistik.de:Wobbl/Bread_Editor.git
+```
+
+You can now start the editor by typing in the terminal: `bread_editor`
