+\section{Introduction}
+\subsection{About \texttt{bangla} Package}
+The \texttt{bangla} package is a programming tool geared primarily towards LaTeX class and package authors. It provides all necessary LaTeX frontends for Bangla language.
+

+Copyright © 2021 Nahid Hossain. Permission is granted to copy, distribute and/or modify this software under the terms of the LaTeX Project Public License, version 1.3c or later.
+\section{Commands}
+\subsection{Use Package}
+The basic command to use the package is-\\ \\
+\com{usepackage}{\{bangla\}}
+    
+
+\subsection{Font Selection}
+\textbf{The default font of the \texttt{bangla} package is \texttt{Kalpurush}. If you do not mention any font name in the parameter, the Kalpurush will be your default font.} However, an author can easily change the font using the parameter of the \texttt{usepackage} command.
+\\ \\ 
+\com{usepackage}{[<font name>]\{bangla\}}
+\\
+
+For example, if an author wants \texttt{Noto Serif Bengali} as the font for the whole article, he can write-
+\\ \\ 
+\com{usepackage}{[notoserifbengali]\{bangla\}}
+\\
+
+
+The following SIL Open Font Licence(OFL) Bangla fonts are currently associated with the \texttt{bangla} package-

+\hline
+Shimanto          & \textcolor{blue}{\texttt{shimanto}} & SIL OFL  \\
+\hline
+Noto Sans Bengali         & \textcolor{blue}{\texttt{notosansbengali}} & SIL OFL\\

+In this subsection, we have demonstrated the commands that requires parameters(at least one or more).
+\subsubsection{\com{banglatext}{\{<bangla text here>\}}}
+\texttt{banglatext} displays any Bangla texts provided inside the parameter. Insert Bangla text in the parameter.\\ 
+\begin{table}[H]

+\hline
+\end{tabular}
+\end{table}
+
+\subsubsection{\com{banglabold}{\{<bangla text here>\}}}
+\texttt{banglabold} bolds the Bangla texts provided inside the parameter. It can make texts bold automatically of any font that has no bold fonts available.\\ 
+\begin{table}[H]

+\hline
+\end{tabular}
+\end{table}
+
+\subsubsection{\com{banglaitalic}{\{<bangla text here>\}}}
+\texttt{banglaitalic} makes the Bangla texts italic provided inside the parameter. It can make texts italic automatically of any font that has no italic fonts available.\\
