dotfiles

Repo containing my personal configuration files and environment. The files can be setup using chezmoi. If you want to use them do the following:

On Windows:

iex "&{$(irm 'https://get.chezmoi.io/ps1')} -b '~/.local/bin' init --apply --force jmigual"

On Linux/Unix:

sh -c "$(curl -fsLS chezmoi.io/get)" -- -b $HOME/.local/bin init --apply jmigual 

This will download chezmoi in the ~/.local/bin/ folder, initialize the repository and apply the configuration. The configuration will be stored in the ~/.local/share/chezmoi directory.
