How to download tex as a .tex file

The core of LaTeX is a backend software package that complies the LaTeX code (.tex file) and creates the final document (PDF).  There are a few different programs available to do this depending on the operating system of the user.   The LaTeX Project provides information about how to install LaTeX on Windows, Macs, and Linux, as well as online services.  Instruction on how to install the most common LaTeX programs for Windows and Mac can be found in the "Installation for Windows" and "Installation for Mac OS X" sections below.

Aside from the back end software required to run LaTeX it is highly recommend that users install a text editor.  A text editor is a frontend software that can be used to create .tex file used by the compiler.  Text editor programs such as TeXwork, TexStudio, TexMaker, and TexShop provide a friendly interface for users.  Often these front end programs include help menus, wizards for creating LaTeX objects, drop down menus for inserting symbols or altering text, and many other features that will support both new and experienced LaTeX users.  You will find more information about these frontend programs in the "LaTeX Interfaces" box below.
