\documentclass{article}
\begin{document}
	\begin{abstract}
		This is a simple paragraph at the beginning of the 
		document. A brief introduction about the main subject.
	\end{abstract}
	
	After our abstract we can begin the first paragraph, then press ``enter'' twice to start the second one.
	
	This line will start a second paragraph.
	
	I will start the third paragraph and then add \\ a manual line break which causes this text to start on a new line but remains part of the same paragraph. Alternatively, I can use the \verb|\newline|\newline command to start a new line, which is also part of the same paragraph.
\end{document}
