+## Q&A
+
+### What's the difference between `fxtwitter.com`, `pxtwitter.com`, and `twittpr.com`?
+
+They all run the exact same worker and have no difference to end users... you can use whatever you'd like!
+
+However, we do consider `fxtwitter.com` to be the primary domain these days, and the public API is only on `api.fxtwitter.com`.
+
+`pxtwitter.com` was our original domain for the project, bought the day before we launched FixTweet (then known as pxTwtiter). I was trying to find something memorable and `px` kinda sounds like "pix" or can mean "pixels" which is fitting as a service that can embed images, videos, etc. Not long after, I bought `twittpr.com` because it's easier to do sed replacement with on Discord (`s/e/p`), and because it had a `p` in it, it was sorta related to pxTwitter. They have always functioned identically.
+
+A couple weeks later, I acquired the `fxtwitter.com` domain from RobinUniverse and alongside this rebranded the project as FixTweet and shifted `fxtwitter.com` to be the primary domain instead of `pxtwitter.com`. Like the addition of `twittpr.com` this domain works identically to the others. I wouldn't go as far as to say `pxtwitter.com` is deprecated, but it certainly is the less preferred domain of the 3.
+
+### How come embedding takes so long / is not working in Telegram?
+
+Telegram's embedding servers sometimes never even send us a request to embed a URL, possibly due to their servers being overloaded. If you have a link that is broken you can try one of FixTweets other domains (`fxtwitter.com`, `pxtwitter.com`, `twittpr.com`) or use [Webpage Bot](https://t.me/WebpageBot) to try to clear the cache of the embed.
+
+### Why doesn't multi-image doesn't work in Telegram?
+
+We've temporarily paused multi-image on Telegram due to issues with its embedding service that can cause images to sometimes not show up at all. ([#15](https://github.com/dangeredwolf/FixTweet/issues/15))
+
+### What if I don't want FixTweet to combine my Tweet's images together with multi-image?
+
+No problem! You can pick any specific photo from a Tweet using Twitter's own URL syntax (`/photo/1` is the first photo of a tweet) and we'll render you the full-resolution original image.
