# how to add notes that start on the left side?

I would like to add notes under the caption of my images. The notes shouldn't be centred but start of the left side. And is there a way to control the vertical distance of the notes from the caption like caption from the image \captionsetup[figure]{font=normalsize,skip=20pt}?

\documentclass[12pt,a4paper]{article}
\usepackage[top=1in, bottom=1in, inner=1in, outer=1in]{geometry}
\usepackage[onehalfspacing]{setspace}
\usepackage[utf8]{inputenc}
\usepackage{ngerman}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{caption}
\captionsetup[figure]{font=normalsize,skip=20pt}

\begin{document}

\begin{figure}[!htb]
\centering
\includegraphics[width=\textwidth,height=\textheight,keepaspectratio]{untitled.png}
\caption{Lohn und Alter}
\end{figure}

\begin{figure}[!htb]
\centering
\includegraphics[scale=0.25]{untitled.png}
\caption{Lohn und Alter}

• For a single line, \makebox[\textwidth][l]{add source/comment, whole width}. For multiline comment, \parbox{\textwidth}{add source/comment, whole width} – Steven B. Segletes Sep 20 '16 at 11:41
