Question: I need to prepare a Licensing Agreement for the software for our product. How do I get started?

Answer: Get some good software installer. When you start installation, it will show its license agreement. Copy it, study it, understand it, edit it, get it approved from the legal folks and use it. Select a software that is closest to what you are writing for. Hardly anyone reads such things, but if you read it carefully, you will be shocked to know that most companies take hardly any liability while selling the software.

I recommend you get a legal advisor involved in this activity. There are a lot of angles to an agreement than what you can appreceate as a Technical Writer.
