 ## Quickstart
 


LaTeX is a sophisticated markup language and processor for typesetting documents.
For a general introduction, read this [LaTeX wiki book](https://en.wikibooks.org/wiki/LaTeX) or any other resource.
In general, it works by editing a "source code", visible on the left, and compiles it to a PDF document.
#{SiteName} manages this task for you, by regularly saving and running the LaTeX processor for you.

On the right hand side, there are several tabs like this one here for help:

* **Preview** quickly renders a few some pages to see how the current part of the document looks like.
* **Issues** lists you all compilation warnings and errors.
  Click on the buttons to jump to the corresponding line in the input code on the left.
  _LaTeX won't compile (or only partially or in a wrong way) as long as there are any errors left!_
* **PDF** shows you an embedded view of the compiled PDF file.


The `\\` character has a special meaning.
It signals a LaTeX command or is used as an escape character.
To enter a backslash, escape its meaning by entering it twice: `\\\\`.

A dollar sign is entered as `\\$`, which escapes the meaning of "formula-start".

### What to do if the preview does not update

Possible reasons:

1. Are there any errors in the "Issues" tab? LaTeX only compiles well if there are zero reported errors.
2. Long documents could take an extended period of time to complete. In the "Preview" tab, disable the preview and only enable it once to avoid piling up too much work on the back-end.
3. Similarly, computational-heavy "SageTeX" computations could lead to excessive compilation times.
   You can pre-compute results or split the document into smaller parts.
