I am trying to use Strophe.js (https://github.com/strophe/strophejs) to create a browser-based XMPP client. However, the documentation doesn't explain how to get it set up and running and the examples provided in the GitHub do not run in a browser. How do I install strophe.js for use with a browser, or what steps should I take to use it in a javascript application that is not using node.js?
You are checking for documentation in github project repo which may or may not necessarily contain the documentation. The correct link for the documentation can be found in the project homepage (link is provided in the repo) as well as the link to the latest documentation (which is also provided in the project repo). Few examples are also included as part of the project repo ( https://github.com/strophe/strophejs/tree/master/examples)
