I want to add a new document class to TexStudio. The document class is named "AEA" and is available in this link (the first .zip file below "Please note:")
The code will look like this
\documentclass[AER]{AEA}
\draftSpacing{1.5}
\begin{document}
Hello World!
\end{document}
*-Article.tex file
where*
is AER or AEJ or JRL as per your choice and use it to type your paper. It should work.
