 A script for sorting pictures (namely, wallpapers) by size. 
 
-It looks for a folder named "wallpapers" in its directory. It then moves all pictures into folders it creates, depending on their size. All pictures that do not fit either a predefined format go in the "SD" folder. 
+We take a folder containing unsorted wallpapers of all sizes and sort them by size by putting them into discrete folders.
 
-# Formats
-## 16:9
-* hd (1920 x 1080)
-* 2k (2560 x 1440)
-* 4k (4096 x 2160)
+# Use
+Create a venv and install requirements:
+```
+python3 -m venv myvenv
+myvenv/bin/activate
+pip install -r requirements.txt
+```
 
-# 21:9
-* 2k (3440 x 1440)
+Take a look at the configuration section inside the script and then launch it.
