	\begin{abstract}
		This document provides a practical guide for authors who wish to prepare their manuscripts using  \LaTeX\ template of the New Journal for Science Vulgarization. It explains the structure of the document, the formatting of sections, equations, tables and figures, and the recommended presentation of references in the journal style.

	\section{Introduction}
The official author guidelines can be consulted at:
\url{https://revues.imist.ma/index.php/NJSV/about/submissions#authorGuidelines}

Authors are requested to prepare their manuscripts in a clear and readable form, ensuring consistency in section headings, proper formatting of mathematical expressions, well-structured tables, and references written in accordance with the journal style.
	
	\section{Writing the manuscript}
	
	\subsection{Sections and text}
	
	The main body of the article should be organized with standard sectioning commands such as \texttt{\textbackslash section} and \texttt{\textbackslash subsection}. The text should remain concise, coherent, and scientifically precise.
	
	The default body text size is already configured in the class file. Authors can therefore focus on the content rather than manual formatting adjustments.
	
	\subsection{Equations}
	
	Mathematical expressions should be written using the usual \LaTeX\ environments. Numbered equations are recommended when the formula is cited later in the text. For example:
	
	\begin{equation}
		E = mc^2
		\label{eq:energy}
	\end{equation}
	
	Equation~(\ref{eq:energy}) shows a simple example of a displayed formula.
	
	\subsection{Theorems and definitions}
	
	The template already provides theorem-like environments. These may be used when the manuscript belongs to mathematics, physics, engineering, or any field requiring formal statements.
	
	\begin{definition}
		A sequence $(u_n)_{n\geq 0}$ is said to be bounded if there exists a constant $M>0$ such that $|u_n|\leq M$ for every integer $n\geq 0$.
	\end{definition}
	
	\begin{theorem}
		If a sequence $(u_n)$ satisfies
		\[
		u_{n+1}=\alpha u_n+\beta
		\]
		with $|\alpha|<1$, then the sequence converges toward the equilibrium value
		\[
		u^\star=\frac{\beta}{1-\alpha}.
		\]
	\end{theorem}
	
	\section{Tables and figures}
	
	\subsection{Tables}
	
	Tables should be centered, readable, and directly related to the content of the manuscript. The following example summarizes the role of the main structural elements used in a manuscript prepared with this template.
	
	\begin{table}[H]
		\centering
		\caption{Main manuscript elements and their purpose in the template}
		\renewcommand{\arraystretch}{1.2}
		\begin{tabular}{p{1.1cm} p{6.1cm} p{6.1cm}}
			\toprule
			\textbf{No.} & \textbf{Element of the manuscript} & \textbf{Purpose and recommendation} \\
			\midrule
			1 & Title, authors and affiliations & Present the identity of the article clearly and indicate the institutional information of all authors. \\
			
			2 & Abstract and keywords & Provide a concise summary of the work and facilitate indexing and thematic classification. \\
			
			3 & Sections, equations and theorem environments & Structure the scientific content and improve readability, especially in technical or mathematical papers. \\
			
			4 & Tables and figures & Organize results visually and support the explanation given in the main text. \\
			\bottomrule
		\end{tabular}
	\end{table}
	
	\subsection{Figures}
	
	Figures should be centered and accompanied by a caption placed below the image. They should remain legible and have sufficient resolution for publication.
	
	\begin{figure}[H]
		\centering
		\includegraphics[width=0.82\textwidth]{banner.png}
		\caption{Example of a figure using the official journal banner.}
		\label{fig:banner}
	\end{figure}
	
	Figure~\ref{fig:banner} illustrates the visual identity used in the first page of the template.
	
	\section{References and citation style}
	
	Authors are responsible for ensuring that the information in each reference is complete and accurate. All references must be numbered consecutively and citations of references in text should be identified using numbers in square brackets.
	
	When the number of authors is greater than 6, the reference should include only 3 authors followed by et al.

	
	\section{Conclusion}
	
Authors must carefully review their manuscripts to ensure consistency in structure and presentation, including sections, equations, tables, figures, and references. All elements should be clearly organized and formatted in accordance with the journal guidelines.
