# Getting Started
|
||
|
|
* Set Up
|
||
|
|
* Windows
|
||
|
|
* Linux
|
||
|
|
* Native
|
||
|
|
|
||
|
|
|
||
|
|
This tutorial page will walk through the process of setting up your computer to build Apple IIgs applications
|
||
|
|
that leverage the GTE toolset.
|
||
|
|
## Set Up
|
||
|
|
|
||
|
|
### Windows
|
||
|
|
|
||
|
|
### Linux
|
||
|
|
|
||
|
|
### Native
|
||
|
|
|
||
|
|
If you are developing directly on an Apple IIgs machine, dowload the GTE-1.0.shk archive into your GS/OS environment. There
|
||
|
|
are several ways of getting the file onto your system.
|
||
|
|
|
||
|
|
1. Use the [NetDisk](https://sheumann.github.io/NetDisk/) utility to mount to the remote disk image directly from GS/OS and copy the Tool160 file
|
||
|
|
1. Use [ADTPro](https://adtpro.com/index.html) to transfer the disk image to the apple IIgs and write it onto a physical floppy disk
|
||
|
|
|
||
|
|
