Konkani is written in more than one script. This site can show you the same writing in Kannada, in Devanagari, or in Romi, which is Konkani written with the same letters as English.
At the top of every page there are three buttons: ಕನ್ನಡ, नागरी and Romi. Tap the one you read most easily. The site remembers your choice as you move from page to page, so you only need to set it once.
Some older pages exist in only one script, because that is the only version we have. When you open one of those, you will see a short line telling you that the page is available in its original script only. The writing is still there and you can still read it. Nothing is hidden from you.
If you send someone a link to a page, the script you were reading in travels with the link, so they see it the same way you did.
