Need to understand how it works

Thank you for this nice forum interface to ask questions. As a new user i need to understand many things but the most important for now is how is it possible to have Obsevable installed on my local web server. I dont now if this is even possible. I am a developer and want to use all the free featurres to make demo app to show others. So, basic setup i went through was online but i could not find any detail on how to make my web app that can be deployed on my domain or local web server. Please guide me with tutorials if possible. Thank you.
