My question is generally about adding
elsarticle document class to TeXStudio.
In the installation documents it says that I should download
.dtx files and compile them with latex. I don't know what it exactly mean.
What I could do was to compile
ecrc-template.tex with TexStudio and start writing inside it. But, without the template, I could not add this class to TeXStudio.
I'd be grateful if you kindly help me with this.
