I am willing to contribute. I just need to know where to add the custom parameters. In your documentation you don't say where to add them. I tried to add them in the same place as your example (loop, after the instantiation of ESPAsync_wifiManager), however the web page /wifi becomes blank after adding the custom parameter via copy paste exactly as it is in the example file.
So, if you will elaborate I will amend the documentation and pull request. I will also amend any other parts that were difficult for me to figure out and make it clear in the documentation where to add and why.

When using the above code the root config page is available but all other pages are blank.
Where do the custom parameters need to be located in the loop to function properly?
