 ## Installation
 
-Installation was tested with Python 3.7 with the following commands:
-
-        pip install --upgrade pip
-        pip install setuptools-rust
-        python setup.py install
-        askbot-setup # answer the questions or use parameters to askbot-setup
-        cd <root_dir> # substitute <root_dir> with the actual directory, default is `askbot_site`
-        python manage.py migrate # assumes that the database specified by askbot-setup is available
+Install as follows:
+
+```
+pip install --upgrade pip
+pip install setuptools-rust
+python -m pip install .
+askbot-setup # answer the questions or use parameters to askbot-setup
+cd <root_dir> # substitute <root_dir> with the actual directory, default is `askbot_site`
+python manage.py migrate # assumes that the database specified by askbot-setup is available
+```
 
 The last command above will create a working Django project in the project root
 directory that you specify with the `askbot-setup` script.
