Custom Weather Page - Coding ?

First post in a long time. I’m reworking my entire weather station, and I’m rewriting all the web pages for the site.

I would like to make a new mywebpagetemplate.txt template, and I’m writing my pages in CSS.

I would like to import the KAOH.TXT data into the page. I’ve not found anyway to code that. Does anyone know of a FAQ or tutorial on how I can accomplish this?
