This post is used to record my $ \LaTeX $ study notes, you can also use it as a dictionary of common symbols. It will be updated for a long time, please make good use the search key (Cltr + F or ⌘ + F)

If you are a LaTeX beginner, I recommend you to read lshort – A short introduction to $ \LaTeX2e $ . I suggest you read it three times, read it once, do it again, and then try to find a paper for $ \LaTeX $ typesetting by yourself for the third time, and check this book again if you find any problems. If you’re just writing notes/homework, this book is perfectly adequate.

2. Download & Configure

This section introduces how to download $ \LaTeX $ and use it in VS Code.

2.1 Install

Download and install the version of $ \LaTeX $ and VS Code that suits you. Install $ \LaTeX $-Workshop in VS Code Extensions. Now we can’t compile .tex files, need to modify config.

2.2 Configure

  1. Click Setting in the lower left
  2. Click Open Setings (JSON)` in the upper right.

The following is my configuration, just copy it.
