+\frametitle{Objectives}
+\label{sec-2}
+
+At the end of this tutorial, you will be able to,
+\begin{itemize}
+\item Get acquainted to LaTeX.
+\item Know why we prefer LaTeX ??
+\item Know about the advantages and disadvantages of typesetting documents using the LaTeX approach.
+\item Have a description, of a typical work flow; which uses LaTeX to typeset documents.
+\item Recognize and differentiate between LaTeX commands, LaTeX comments and special characters, spacing and actual document content.
+\item Create and compile a very simple LaTeX document.
+\end{itemize}

+    \begin{itemize}
+      \item Typesetting program
+       \begin{itemize}
+         \item What is typesetting?
+       \end{itemize}
+      \item Excellently Typeset Documents - specially Math
+      \item Anything from one page articles to huge books
+      \item Pronounced \emph{Lah-tech} or \emph{Lay-tech}
+    \end{itemize}

+  \frametitle{Why \LaTeX?}
+  \begin{itemize}
+  \item Excellent visual quality! 
+  \item Handles the typesetting; Lets you focus on content
+  \item Makes writing math extremely simple
+  \item It is a standard -- widely used in Scientific community
+  \end{itemize}
+  \begin{block}{}
+    \[\tilde{N}_{\mathbf{x}}\times \mathbf{r}(\mathbf{x}) f_{1k}(\mathbf{x},t) - \frac{1}{2} \tilde{N} \tilde{N}:\mathbf{BB}^{T}P(\mathbf{x},t) = -m_{k}f_{1k}(\mathbf{x},t) + 2 \mathop{\mathbf{\aa}}_{j=1}^{K} f_{1j}(\mathbf{x},t)m_{j}P_{k|j} \]

+  \frametitle{Why \LaTeX?}
+  \begin{itemize}
+  \item {\LaTeX} is a document based mark-up
+  \item Mark-up $\rightarrow$ a system of annotating text, adding extra
+    information to specify structure and presentation of text
+  \item Document based markup $\rightarrow$ you don't have to worry
+    about each element individually 
+  \item Allows you to focus on content, rather than appearance.
+  \end{itemize}

+  \frametitle{Advantages of using \LaTeX }
+  \begin{itemize}
+  \item Easy availablity of professional templates.
+  \item Typesetting complex formulae in a convenient environment.
+  \item Can start typesetting with very little effort.
+  \item Presence of a lot of add-on packages.
+  \item Encourages creation of well structured texts.
+  \end{itemize}

+  \frametitle{Disadvantages of using \LaTeX }
+  \begin{itemize}
+  \item Designing whole new layout is difficult.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{\LaTeX \ input file format}
+  \begin{itemize}
+  \item \LaTeX takes ASCII text file as input.
+  \item We can compile \LaTeX files into DVI,Postscript or PDF files.
+  \item \alert{Note:} \typ{latex} vs. \typ{pdflatex} 
+  \end{itemize}
+\end{frame}

+
+\begin{frame}[fragile]
+  \frametitle{Commands, Comments and Special Characters }
+  \begin{itemize}
+  \item {\LaTeX} is case sensetive.
+  \item Commands begin with a \typ{\\}
+  \item Environments have a \typ{\\begin} and \typ{\\end} 
+  \item Any content after the \typ{\\end\{document\}} is ignored
+  \end{itemize}
+  \begin{itemize}
+  \item Anything that follows a \typ{\%} symbol till end of the line
+    is a comment 
+  \item Special characters (\typ{\~ \# \$ \^ \& \_ \{ \}}) are escaped by a
+    \typ{\\} 
+  \item \typ{\\} symbol is inserted using \typ{\\textbackslash}
+    command
+  \end{itemize}
