+To setup and run:
+
+run `install-deps.sh` to prepare the python venv and install packages:
+
+    chmod +x ./install-deps.sh && ./install-deps.sh
+
+then, you need to source the venv. Run 
+
+    source venv/bin/activate
+
+or 
+
+    source venv/bin/activate.fish
+
+if you use fish shell.
+
+Then you are good to go to execute any python file.
