NOTES


Run unpack.bat (Windows) unpack.sh (Linux/Mac). This will automatically:

Create a templates folder, move S2A_gallery.html inside.
Create a static folder, move S2B_gallery.css and S2C_gallery.js inside.
Create a virtual environment - virtualenv venv.
Activate the virtual environment - venv\scripts\activate (Windows) venv/bin/activate (Mac/Linux)
Install Flask - pip install flask


Put your own video files inside static.
Run python S1_server.py to start the server, and access http://localhost in your browser.
