Plugins are managed by Vundle, which is a git submodule. After cloning the `dotfiles` repository, you have to initialize the submodule and install all plugins.
``` console
cd dotfiles/
git submodule init
git submodule update
vim +PluginInstall +qall
```
Plugins can be updated with `vim +PluginUpdate +qall`.
The wallpaper is randomly set from images (png, jpg and jpeg) from `~/pictures/wallpapers/enabled/`. You should populate this directory with symbolic links pointing to images stored in `~/pictures/wallpapers/`.
