-# Migrating from yuzu
-
-When coming from yuzu, the migration is as easy as renaming some directories.
-
-## Windows
-
-Use the run dialog to go to `%APPDATA%` or manually go to `C:\Users\{USERNAME}\AppData\Roaming` (you may have to enable hidden files) and simply rename the `yuzu` directories and simply rename those to `suyu`.
-
-## Unix (macOS/Linux)
-Similarly, you can simply rename the folders `~/.local/share/yuzu` and `~/.config/yuzu` to `suyu`, either via a file manager or with the following commands:
-```sh
- $ mv ~/.local/share/yuzu ~/.local/share/suyu
- $ mv ~/.config/yuzu ~/.config/suyu
-```
-There is also `~/.cache/yuzu`, which you can safely delete. Suyu will build a fresh cache in its own directory.
-
-### Linux
-Depending on your setup, you may want to substitute those base paths for `$XDG_DATA_HOME` and `$XDG_CONFIG_HOME` respectively.
-
-## Android
-TBD
