This documentation covers the following topics:

General Installation Information | About the installation jobs. Prerequisites for Natural ISPF. Contents of the installation medium. How to migrate from a previous version.
Installation Procedure | How to install Natural ISPF in the various environments supported by the current version of Natural ISPF.

Further customization facilities are described in the Natural ISPF Programmer's Guide.

## Naming Conventions

In the description of installation procedures, all file names that contain the notation `ISPvrs` refer to the current version of Natural ISPF, where `vrs` stands for version number, release level and SM level. For the current value of `vrs`, see the label of the installation medium.

The section Natural ISPF Libraries of the Natural ISPF Administration Guide contains a table that lists all Natural ISPF libraries as they appear after loading the installation medium, together with a descriptive name as to the library content. For example, a library named `SYSISPX` could be the Exit Library.
