+This is a pure Python editor to make PyUnity projects (see https://github.com/pyunity/pyunity).
 PyUnity is a pure Python Game Engine that is only inspired by Unity and not bindings for Unity,
 therefore this Editor is completely separate, but inspired by the UnityEditor.
 
 ## Installing
 
 The PyUnity Editor can be installed via pip:
 
-> pip install pyunity-editor
+    > pip install pyunity-editor
 
 Alternatively, you can clone the repository to build the package from source. These builds are sometimes broken, so use at your own risk. You can build as follows:
 
-> git clone https://github.com/pyunity/pyunity-gui
-> git checkout master
-> python setup.py install
+    > git clone https://github.com/pyunity/pyunity-gui
+    > git checkout master
+    > python setup.py install
 
 Its only dependencies are PyUnity, PyQt5 and Pillow. Microsoft Visual C++ Build Tools are required on Windows for building PyUnity from source (if there isn't a wheel available). The PyUnity Editor requires a PyUnity version of at least 0.7.1.
 
 ## Running
 To run the PyUnity Editor, you run this command from the terminal:
 
-> pyunity-editor project/
+    > pyunity-editor project/
 
 where `project/` is your project folder. The PyUnity Editor will launch with a splash screen, then the editor window will appear.
