I write my thesis using:
\documentclass[12pt]{report}
\noindent\textbf{\huge Incoming Records Classificatio gdhjkdfhlfgdfldgslfgdfldhfjhfgklhdfslhfgfdhsjhgflfgjlfsdghfgsd}
\section{Introduction}\label{sec:intro}
However, I get the title in which there is no space between lines.
In addition, each new section starts with 0. as can be seen in following: 

\parimmediately aftergdhjkdfhlfgdfldgslfgdfldhfjhfgklhdfslhfgfdhsjhgflfgjlfsdghfgsd. (Aside: I'm assuming [hoping?!] that you don't plan on typesettinggdhjkdfhlfgdfldgslfgdfldhfjhfgklhdfslhfgfdhsjhgflfgjlfsdghfgsdin your real document...) – Mico May 05 '19 at 13:56\chapterinstead of\sectionor alternatively, use thearticledocumentclass instead ofreport. Regarding the title, you might also be interested in\title{...}and the\maketitlecommand. – leandriis May 05 '19 at 14:00
