 Redash uses [GNU Make](https://www.gnu.org/software/make/) to run things, so if you're not sure about something it's often a good idea to take a look over the [Makefile](https://github.com/getredash/redash/blob/master/Makefile) which can help. :smile:

 Then create a Python virtual environment, for safely installing Python libraries without affecting Python on the rest of the system:
 
 ```
+
 $ python3 -m venv ~/redashvenv1
 $ source ~/redashvenv1/bin/activate
+
 ```
 
 When the Python virtual environment is active in your session, it changes the prompt to look like this:
 
 ```
+
 (redashvenv1) $
+
 ```
 
 With that done, install the rest of the Python dependencies:
 
 ```
+
 (redashvenv1) $ pip3 install wheel  # "wheel" needs to be installed by itself first
 (redashvenv1) $ pip3 install --upgrade black ruff launchpadlib pip setuptools
 (redashvenv1) $ pip3 install poetry
 (redashvenv1) $ poetry install --only main,all_ds,dev

 ```
 
 # Configuring Pre-commit
 
 Before committing changes to GitHub or creating a pull request, the source code needs to be checked and formatted for certain quality standards:
 
 ```
-(redashvenv1) $ make format
+
+(redashvenv1)$ make format
 pre-commit run --all-files
 isort....................................................................Passed
 black....................................................................Passed
 flake8...................................................................Passed
+
 ```
 
 Enabling Pre-commit check before commit.
 
 ```
+
 (redashvenv1) $ pre-commit install
 (redashvenv1) $ git commit -m 'Added xxx'
+
 ```
