+LaTeX is a typesetting program that produces excellently typeset documents. 
+Typesetting is placing text onto a page with all the style formatting defined,
+so that content looks as intended. It is extensively used for producing high 
+quality scientific and mathematical documents. It may also be used for 
+producing other kinds of documents, ranging from simple one page articles to

+LaTeX, like most utilities in Linux, LaTeX is case sensitive. Commands begin 
+with a backslash.LaTeX environments have a begin and end marker. The begin and
+end document commands, mark the beginning and the end of the content of the 
+LaTeX document. The text in between the begin and end commands is typeset in 
+the output document.Any content after \end{document} is ignored. The type of 
+document that is being currently typeset in LaTex, is identified with the 
+documentclass command. LaTeX then, typesets the document accordingly. 
 
-Anything that follows a percentage sign (%) till the end of that line is a
-comment. Special characters like tilde or hash,etc have to be escaped by a
-backslash. If you have to insert a backslash into a LaTeX output file, you have
-to use the LaTeX command \textbackslash.
+All the commands in LaTeX begin with a \. An environment begins with a begin
+command and ends with an end command. 
 
-Normally LaTeX automatically spaces the given input optimally. But, sometimes we
-have to insert manual line breaks. This is achieved using the \\ command.
+So, as expected LaTeX ignores anything that is written after the \end{document}
+command. Essentially, anything written after the \end{document} command turns 
+out to be a comment. But, how do we write comments with in the document. % is
+the character to indicate comments. Anything written after a % symbol in a 
+line, is ignored.
 
-We can also start a new paragraph using an empty line.

-It must be noted that multiple spaces/empty lines are automatically compressed 
-to a single space/line.

+
+But what if we wanted to insert the % symbol in the document? We can do so by
+escaping it with a \ (backslash). % is one of the many special characters in
+LaTeX. The others are, ~ # $ ^ & _ { } \. All of them, except the \ itself, can
+be inserted by escaping it with a \. To insert a \ in our document, we use the
+command \textbackslash.
+
+What would happen if we escape a \ with a \? 
+A double backslash is actually another command. It inserts a new line in the
+typeset document. Normally LaTeX automatically spaces the given input optimally.
+But, sometimes we have to insert manual line breaks. The \\ command or \newline
+command is used to insert a newline in the output document. Line breaks in the
+input document, do not translate into line breaks in the output document. A 
+single line break in the input document, doesn't cause any change in the output. 
+
+A single empty line causes a change in paragraphs in the output. (Multiple 
+empty lines are equivalent to a single empty line.) Similarly, multiple spaces
+are treated as a single space.
