This document is an attempt to give you all the essential information that you will need in order to use the LATEX Document Preparation System. Only very basic features are covered, and a vast amount of detail has been omitted. In a document of this size it is not possible to include everything that you might need to know, and if you intend to make extensive use of the program you should refer to a more complete reference. Attempting to produce complex documents using only the information found below will require much more work than it should, and will probably produce a less than satisfactory result.
The main reference for LATEX is The LATEX User's guide and Reference Manual by Leslie Lamport (M05.04-200). This contains all the information that you will ever need to know about the program, and you will need access to a copy if you are to use LATEX seriously.
Both the Manual and this document avoid mentioning anything that depends on the particular computer system that you are using. This is because LATEX is available on a number of systems and they all differ in one way or another. Instead, they both refer to a local guide for their particular system. For LATEX on the Prime, the local guide is the handout The Local Guide to LATEX on the Plymouth Prime System (U05.04-201).
