Designing Installation Manuals Used in Various User Environments 
Manuals normally contain information regarding all the functions of a given product. Therefore, there are cases when information required by one user is useless to other users. As a typical example, for users, performing a version upgrade, the upgrading procedure is important, but the procedure for new installation is useless information.
