-## Searching
-
-```mkshell
-> s: {querry or url}
-
-# examples
-> s: https://musify.club/release/some-random-release-183028492
-> s: r: #a an Artist #r some random Release

-Searches for an url, or an query
-
-### Query Syntax
-
-```
-#a {artist} #r {release} #t {track}
-```
-
-You can escape stuff like `#` doing this: `\#`
-
-## Downloading
-
-To download something, you either need a direct link, or you need to have already searched for options
-
-```mkshell
-> d: {option ids or direct url}
-
-# examples
-> d: 0, 3, 4
