+Tools to switch between dark and light mode of some tools I use.
+
+## Switch themes
+
+You can switch all themes at once with the `switch-themes.sh` script. When
+called without arguments, switches from the current to the other. Can be called
+with either `dark` or `light` to choose a specific:
+
+```bash
+./switch-themes.sh "dark"
+```
+
+The `auto-themes.sh` script switches your themes by daytime. It requires the start and end time of the **light** theme as argument and will set the dark theme in all other cases. Call it for example via cron (e.g. every 5 minutes):
+
+```cron
+*/5 * * * * $HOME/.local/share/theme-switchers/auto-themes.sh "09:00" "23:00"
+```
+
+### GNOME
+Regarding the [GNOME Desktop](https://www.gnome.org/):
+Uses `gsettings` to switch between dark and light mode.
+
+When called without arguments, switches from the current to the other. Can be
+called with either `dark` or `light` to choose a specific:
+
+```bash
+./gnome-switch-theme.sh "dark"
+```
+
+### Helix
+
+Regarding the [Helix editor](https://helix-editor.com/):
+Overrides the `theme` variable within the `config.toml` file.
+
+When called without arguments, switches from the current to the other. Can be
+called with either `dark` or `light` to choose a specific:
+
+```bash
+./helix-switch-theme.sh "dark"
+```
+
+Requires a dark and light theme to be defined in
+`~/.config/helix/autothemes.toml`:
+```toml
+theme_dark = "onedark"
+theme_light = "onelight"
+```
