There are 3 columns

• File tree
  • All files placed in here can be called in your document. E.g. data files, images, bibliography, etc.
• Source code
  • Where you’ll do most of your work
  • Content goes here
• PDF generated
  • When you compile your code, you can immediately see how the PDF will look like

In general, LaTeX documents (.tex file) have 4 distinct parts 

• Preamble
  • Defines the document type
  • Includes packages 
• Top Matter
  • \begin{document}
• Sections
  • i.e. content
• Bibliography
  • Includes bibliography and \end{document}

Packages are add-on features for LaTeX. Dozens of these are pre-installed with LaTeX and can be used in your documents immediately.

A package is a file or collection of files containing extra LaTeX commands and programming which add new styling features or modify those already existing.

Loads the package into LaTeX: 
\usepackage{ }

Example packages for Maths & equations: 
\usepackage{apacite}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amsfonts}

Environments are used to format blocks of text in LaTeX documents.

Simple examples of environments:

\begin{center}
This text will be centred since it is inside a special 
environment. Environments provide a efficient way of modifying 
blocks of text within your document.
\end{center}

\begin{equation} 
x+y=67
\end{equation}
