I have no experience in using Latex, but I am planning to use it for publishing purposes. Could you please recommend any resources that help me to learn in less time (at least the basics on how to publish an article using it)?
At the start, you choose one of currently eight languages (Catalan, German, English, Spanish, French, Marathi, Portuguese, Vietnamese). Subsequently, all teaching is going to be provided in this language only.
Later, you enter 16 core lessons; all at your pace, without hassle of installation. These cover elementary concepts like document classes for articles, books, slides; how to interact with graphics, how to embed mathematics, the use of cross-references and citations. Contrasting to other starter kits, the organization of larger projects with LaTeX2e or debugging errors equally is part of the game. You train from your browser:
For work and generation of the .pdf in Overleaf (left hand button), a platform equally set up for collaborative edit, you need a log-in. Your school may be among the subscribers. To run the small examples, the work with TeXLive/LaTeX online (right hand button) does not require a subscription.
Then, according to the language selected, there are special lectures. For example, by TeX's age and origin in the States, the input of characters not covered by ASCII 7-bit (like in matériaux, polymères, École, garçon, Nöel from the Latin script) or use of a dedicated hyphenation pattern requires some information.
The project doesn't aim to be an encyclopedia. Joseph Wright, the moderator of the project, equally is maintainer of extensions for LaTeX2e (e.g., siuntix) and moderator on https://tex.stackexchange.com/. If your native language is not yet among the eight, you may contribute to the project's extension via GitHub, too.
I personally started with "The Not So Short Introduction to LaTeX", a PDF file that should come with most LaTeX distributions under the name "lshort.pdf". The document claims that it can be read in 139 minutes (the precise number depends on the version). I remember I didn't finish it in such a short time (perhaps the given time estimate was for native English speakers, which I'm not) but in the worse case it won't take you more than half a day to read. While you read it, it's beneficial to create a tex file, actually type some commands (including inserting equations, tables, graphics, etc.) into it and compile the file.
lshort.pdf does not contain all information you need, but the remaining intricacies are usually sufficiently few that you won't have much trouble googling them every time you encounter them. Another great resource for LaTeX-related problems is the LaTeX stack exchange, although googling LaTeX-related questions will usually lead you there anyway.
If you are already relatively certain about the journal that your next paper will be submitted to, it's also beneficial to download the LaTeX template of that journal, once you learned the basics of LaTeX. It may save you some time if you type your article directly into that template, and frequently compile the document before you finish, to detect and correct the errors as soon as possible, so that you don't repeat any given error when you write the subsequent sections of the paper.
Learning Latex to create documents is like becoming a mechanic to learn how to drive a car. Lyx is based on the Latex typesetting system, but provides a content-focused "live preview" editor that doesn't expose the inner workings to the user. Advanced formatting is still possible, with lots of it made accessible to the user through meaningful GUI interaction.
If you've ever had to write complicated equations (or, god forbid, tables!) in pure Tex, you'll very quickly understand why this program is so useful.
