# VIM

This repo contains my vim configuration, hope it will be useful for you.

## Installation

You will need `vim` and `git` to be able to use this configuration.

Normally if you run the `install.sh` script it will work, but if you have a problem, try to install vim plug and check if your problem is solved.

```bash
curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
