+## Konsole
+
+The appearance of Konsole is controlled by text files called colorschemes. These files cannot be edited on-the-fly, thus a reference colorscheme must be created. Copy or symlink the desired file to `~/.local/share/konsole/Pokemon.colorscheme`. Local colorschemes are found in the same folder while system colorschemes are found in `/usr/share/konsole`.
+
+Since Konsole doesn't support on-the-fly editing of colorschemes, a colorscheme file is created on-demand for each Pokemon. The created files can be removed with ```rm ~/.local/share/konsole/p--*```.
