+## Usage & Configuration
+Install circadian.el with
+[use-package](https://www.gnu.org/software/emacs/manual/html_mono/use-package.html)
+or [straight.el](https://github.com/radian-software/straight.el)
 
-##### Switching themes on time of day
+### Configuration with times
+To auto-switch a theme on a specific time, use time strings:
+
+```elisp
+(use-package circadian
+  :ensure t
+  :config
+  (setq circadian-themes '(("8:00" . wombat)
+                           ("19:30" . adwaita)))
+  (circadian-setup))
+```
+
+
+### Configuration with `:sunrise` and `:sunset`
+To auto-switch a theme based on your current locations sunrise and sunset times:
+
+1. Make sure to set your latitude and longitude (Get them e.g. at
+   [latlong.net](https://www.latlong.net/)):
+    ```elisp
+      (setq calendar-latitude 40.712776)
+      (setq calendar-longitude -74.005974)
+    ```
+2. Configure `circadian-themes` using the `:sunset` and `:sunset`
+    ```elisp
+    (use-package circadian
+      :ensure t
+      :config
+      (setq circadian-themes '((:sunrise . adwaita)
+                               (:sunset  . wombat)))
+      (circadian-setup))
+    ```
+
+
+### Randomly selection from theme list
+Circadian.el can randomly select a theme from a given list, e.g here using [doom-themes](https://github.com/doomemacs/themes) at sunset:
+
+```elisp
+(use-package doom-themes)
+
+(use-package circadian
+  :config
+  (setq circadian-themes '((:sunrise . doom-gruvbox-light)
+                           (:sunset . (doom-dracula doom-gruvbox))))
+  (add-hook 'emacs-startup-hook #'circadian-setup)
+  (circadian-setup))
+``` 
+
+
+### Use with custom themes
+To use custom themes, install them from MELPA using
+e.g. [use-package](https://www.gnu.org/software/emacs/manual/html_mono/use-package.html)
+or [straight.el](https://github.com/radian-software/straight.el).
