Help me become AGPL compliant from OS project?

Hello first time entrepreneur, and was recently made aware of that I am not properly meeting the AGPL requirements for an OS software on which I used to build my Micro-SaaS.

Here are the requirements:

Users of AGPL-licensed code must:

• Include a copy of the full license text and the original copyright notice

• State all significant changes made to the original software

• Make available the source code when you distribute any works based on the licensed software

• Include any installation information necessary to update and reinstall the software if the program is being used as part of a consumer device

I understand the part where I have to make the code available as Open Source (and I am working through that) but I am a little lost at the Giving "proper attribution" to the original project. What does proper attribution look like and what should I do to meet the requirement and give the proper credit!

I launched about a week ago and this is what I had on our "about us" page giving the original project "plausible" credit ( https://www.getmangoo.com/about ) of the software but looks like this may not cut it?? What should I do to become compliant.

I decided to launch from a OS solution because I love their product and I believe I can also help other customers around the world better reach this type of product and I also plan of adding some features from feedback from customers.

Thanks in advance!
