I'm trying to indent the first line of each paragraph in the cover letter of the `moderncv` template. So far I added this at the beginning of the .tex to justify it, but I haven't found a way to indent. 

```
\documentclass[11pt,a4paper,sans]{moderncv} % Font sizes: 10, 11, or 12; paper sizes: a4paper, letterpaper, a5paper, legalpaper, executivepaper or landscape; font families: sans or roman

\moderncvstyle{casual} % CV theme - options include: 'casual' (default), 'classic', 'oldstyle' and 'banking'
\moderncvcolor{blue} % CV color - options include: 'blue' (default), 'orange', 'green', 'red', 'purple', 'grey' and 'black'
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox
\makeatletter
\patchcmd{\makelettertitle}% <cmd>
    {\raggedright \@opening}% <search>
    {\@opening}% <replace>
    {}{}% <success><failure>
\makeatother

```

Can I add anything in there to indent? Or should I do something else? 

-- Edit -- 

This is the letter part in the code 

```
 \clearpage

 \recipient{Empresa contratante}{A coruña, España} % Letter recipient
 \date{\today} % Letter date
 \opening{Estimados Srs,} % Opening greeting
 \closing{Atentamente,} % Closing phrase
 \enclosure[Adjunto]{Curriculum vit\ae{}} % List of enclosed documents

 \makelettertitle % Print letter title

 This is the part where I write my letter and I want it to be indented

 \end{adjustwidth}

 \makeletterclosing % Print letter signature

```
