Hi all, I am new here and will be needing guidance and assistance from you all. Thank you.
Welcome to Confluence @m_ganga! This is a life changing moment for you. Take a deep breath and survey your surroundings - you'll want to remember this in the years to come!
Atlassian University has some great free (and paid) resources. I highly recommend you take the Confluence Fundamentals course, which is free, recently revamped, and an excellent primer for how to use Confluence.
I also recommend you create a personal Space in your Confluence instance and just start playing there with creating, editing, formatting and using macros for pages and content - hands on experience is the best experience to learn from!
A few more resources:

And of course, keep coming back here with questions and we'll be here to support you on your journey!
