Instalation command have a wrong path

The commands with right path is here:

```
git clone git@github.com:mboughaba/i3config.vim.git /tmp/i3config.vim
mkdir -p ~/.vim/after/syntax/
mv /tmp/i3config.vim/syntax/i3config.vim ~/.vim/after/syntax/i3config.vim
rm -rf /tmp/i3config.vim
```

In 3rd line the path was `/tmp/i3config.vim/after/syntax/`, the right path is: `/tmp/i3config.vim/syntax/`
