This Linux localization guide is a compilation of the experiences of the Madan Puraskar Pustakalaya localization team while they worked on the localization of Debian and Morphix based GNU/Linux Distribution in Nepali. Special attention has been given in making the content useful to those undertaking the localization work for the first time for other countries in their respective languages. Illustrations in most cases are based on the works in the Nepali language. However, information about the basic steps and procedures for localization has been made as generic as possible, in order to ensure that any language may fit into the description provided. During the preparation of this guide, a large number of resources invaluable to both beginners and experts of localization have been consulted. References have been provided for further reading for these topics.
