+=== https://github.com/dylanaraps/pywal[Pywal] 
+
+Pywal is a tool for generating color schemes from an image. 
+It is mainly used to produce templates for different applications (e.g., Vim, Visual Studio, the tty). 
+
+* The config directory is at `wal`. 
+* The usual target path would be on `~/.local/share/wal`. 
+The target path is more lenient since it only contains data files. 
+You have more choices here. 
+* Minimum version (from `wal -v`):
+** `wal 3.3.0` 
+* The folder only contains a bunch of themes in JSON files. 
+All of the data files are named after the filenames of the wallpapers. 
+A few of them are listed in the <<Wallpapers>> section for the sources. 
+The JSON files does need a little bit of tweaking especially with the `wallpaper` key. 
+You could apply them with `wal --theme /path/to/file`. 
+* To easily create some more themes into JSON, I've created a small script named `create-wal-theme` located in my custom scripts location.
