 \subsection{Input/output description}
+Input is a .tex file (\LaTeX \, file) \\ 
+Outpus is an .html file \\ 
+In case of errors error message will be outputed on the terminal \\
+Input File path is entered as an argument to terminal with "-i" or "--input" flag for example:
+\begin{lstlisting}[language=bash]
+python main.py -i texFile.tex
+\end{lstlisting}
+Output file path can be named by user by using "-o" or "--output" flag:
+\begin{lstlisting}[language=bash]
+python main.py -i texFile.tex -o htmlFile.html
+\end{lstlisting}
+If no "-o" flag is issued the output file will have the same name as input file with changed extension to html (so in this example texFile.tex will become texFile.html) \\ 
+If the path to file name consists of spaces, path name needs to be but in ""
+\begin{lstlisting}[language=bash]
+python main.py -i "My Folder/input.tex"
