hey @asad-mlbd I thought of creating a PR for this, but I am not sure how to ensure that users are able to add denon as a dependency to their project. Presently the documentation of denon installs the denon package in the ~/.deno/bin folder so if someone is to download this repo they will still need to go through and execute the installation command for denon to function even if there was a scripts.json file in the root folder. Let me know how if you have any ideas on how we can get around this and I'd be happy to take it forward. P.S. Thanks for putting this repo up, it's a great way to quickly get started with a deno project and a real time saver.
