Here I'll share a bit of my experience about how to learn \LaTeX
from zero, the best editor for \LaTeX
(IMO) as well as typical mistakes.

It is a requirement for any programming activity. Open any trainer for blind printing with ten fingers — and go ahead!
How To Learn
-
I recommend this free online introduction to
\LaTeX
in three parts, made by Overleaf. Instead of a dry book guide, they made it as a presentation. There are a lot of examples, with a focus only on the most important stuff. This introduction should take about 4-hours for you to read.Also, Overleaf has great docs. Later, when you have some questions about
\LaTeX
, you can look it up in their docs. -
Videos are usually the easiest way to learn, and for a quick start in
\LaTeX
take a free course from the HSE (in Russian).The basics could be learned in 4-5 hours, and two days off are enough for the entire course. Video lessons are better than thick books in the beginning.
Where To TeX
There are two ways.
- Online compiler like overleaf.
- Very simple.
- Real-time online teamwork.
- Set up your environment.
- So much faster compiling!
- Takes time.
- Easier to integrate Git.
GUI / Text Editor for LaTeX
The best option, in my opinion, is LaTeX
in Vim
. There are gold articles in which Gilles Castel shows his Vim
+ LaTeX
setup and how it works.
Otherwise — you can try TexStudio
, but it looks like an ancient artifact.
Also, there is the texpad
app for macOS, but I had some issues with buggy behavior (in 2020).
PS: The Vim
+ LaTeX
setup can easily take 20+ hours to make it work if you are new.
Life Hacks
-
Use
\newcommand{command_name}{script_of_command}
for commands you use very often.Compare
f: \mathbb{R} \to \mathbb{R}
andf: \R\to\R
.

Typical Mistakes
-
Please, God, don't do 500+ lines main.tex...
- It will be an unmaintainable mess.
- You don’t have a universal preamble.
Instead -- use
input{anotherFile.tex}
orinclude{anotherFile.tex}
to structure code. -
Not using or defining
LaTeX
environments.
For every theorem, proof, note, etc. you can set special environment (\begin{theorem}
,\begin{proof}
).- Now you can change the style of your theorems by changing one line.
-
Not using
multiline
oralign
environments for long formulas.
\begin{align*} a &= b + c + d - d \\ &= b + c \end{align*}
-
Not using
\cfrac
or\displaystyle
when necessary.- Otherwise, the formula may get hard to read.
-- without
\displaystyle
-- with
\displaystyle
-
Not using
\text
inside formulas.
\begin{align*} a &= a + b + c + d , when\; sun\; is\; red \\ a &= b + c, \text{ when sun is white} \end{align*}
-
All variables inside text should be math mode.
-a or
-
Avoid making new lines in text with
\\
.- Using empty lines instead makes code much more readable.
-
Not using
\ldots
for ...... or
-
Ignoring warnings and errors.
- You must not ignore erros.
- Warnings help you deepen your knowledge and improve code.
Not using
Git
for big projects.
Best of luck...Using tutorials from ancient times.
You can meet outdated and deprecated practices.
