if zsh start up is really slow, first try restarting computer, then try running zsh with `zsh -lvx`. LPT if on iterm put that as the start command in a profile

    docker
    docker-compose

    tmux

    ruby

you have to symlink the layer into ~/.emacs.d/private/
then add the name of the layer into `~/.spacemacs` in `dotspacemacs-configuration-layers`
like this:
```
   dotspacemacs-configuration-layers
   '(
     personal-layer
    ... a bunch of stuff already here and comments
    )
```
NOTE: we do not sync the .spacemacs file with vcs cause it's a pain in the ass and stores a lot of state.
Just init emacs for the first time, choose the basic normal settings, add the layer then restart emacs.

    $dotfiles/spacemacs/.spacemacs $HOME
