+# FOR WINDOWS USERS
+
+## MPV
+MPV insists on opening a GUI (or "pseudo-gui" as they call it) window, whether you like it or not.
+So, here is the best mpv.conf I could come up with, under those
+circumstances:
+```ini
+[default]
+terminal=yes
+audio-display=no
+video=no
+force-window=no
+window-minimized=yes
+idle=yes
+```
+The window will still be created, but at least, it will be minimized to the taskbar.
+
+You should put this file in: `%USERPROFILE%\AppData\Roaming\mpv.net\mpv.conf`
+
+## RADIOSTATIONS.INI
+Make sure your `gostations.exe` is somewhere in your searchable %PATH%. Then, you should 
+only need to change the player.command option:
+```ini
+[DEFAULT]
+radio_browser.api=all.api.radio-browser.info
+player.command=mpvnet.exe
+player.options=--no-video
+menu_items.max=9999
+```
+
+# FOR EVERYONE ELSE
+
+Continue as you are. The sane people don't need to do anything different.
