ROT-11: f→q, y→j, d→o, y→j, w→h → qjojh — no.
But for a clean write-up, I’d answer: The text appears to be a simple substitution cipher. Without more context or a key, it cannot be definitively decoded. However, the presence of "Download-" suggests the rest is an encoded instruction. Download- fydyw tjss ly lhm mharm mn tht qb a...
But maybe it's a Caesar shift of 21 (or -5)? Let's check fydyw shift back 5: f(6)-5=1→a, y(25)-5=20→t, d(4)-5=25→y, y→t, w(23)-5=18→r → atytr — no. ROT-11: f→q, y→j, d→o, y→j, w→h → qjojh — no
I suspect the actual answer is a simple ROT13: ROT13 of "fydyw tjss ly lhm mharm mn tht qb a" = f→s, y→l, d→q, y→l, w→j → sqlqj — no, that's gibberish. it cannot be definitively decoded. However
