 You should see the blue screen of river. Try to open terminal with Win+Shift+Enter. Try to exit with Win+Shift+E.
 
+### Login manager

+To enter username/password in GUI, get to river after that, and get back to logon screen after exiting river:

+doas rc-update add elogind

+and reboot.
+
+I didn't find a way to make cage+gtkgreet handle HiDPI, the text is very tiny.

+An alternative is agreety, but for some reason it seems that both greeter and standard linux login prompt
+run at the same time on the same terminal, making it impossible to actually login.

 ### Installing Waybar

+#### HiDPI - cursors
+
+And in order to have decently sized mouse cursors instead of the tiniest ones, add the following line to the top of `.config/river/init`:
+
+```
+riverctl xcursor-theme Adwaita 24
+```
+
+This will only affect river itself, the cursor will stay tiny in waybar and firefox and maybe other applications. To solve this:
+```
+doas apk add gsettings-desktop-schemas
+gsettings set org.gnome.desktop.interface cursor-theme 'Adwaita'

+### Environment
+
+In order to not have to create wrapper scripts for all apps:
+
+Create `/usr/local/bin/inga-river` (and later `chmod +x /usr/local/bin/inga-river`) with the following (found in google):
+
+```
+#!/bin/sh
