%In lengthy documetns, it is convenient to divide the tex file into several subfiles. This can be done,for example, with the package "subfile".
%Each chapter is being imported from the sections folder.
%In order to edit the chapters, edit the respective tex file.
%To add or delete chapters simply use \subfile with the folder name followed by the tex file of the chapter. (\subfile{sections_folder/section}
%If you would prefer to have only one main file, remove \subfile{sections_folder/section} and edit this file directly instead.
