# Licensing The free community edition of Class 4 Fusion is free for 500 ports. We provide you different ways of installing your own community edition on your server, VM, AWS/Google Instance. This cookbook provides you a very detailed step by step instruction on how you can install DNL Class 4 Fusion. The Community Edition has the same feature as a commercial version, with the exception that only 500 ports is supported. If you need help from DNL to install for you, you can do the following: 1. Send a $100 USD installation service fee to DNL via this [`link`](https://buy.stripe.com/14kg1CbuN049fokaEE). 2. Fill out the installation questionnaire via this [link](https://forms.gle/T5Q9DA74TnkgebAd6). If you feel 500 ports is not sufficient, then you can purchase additional licensing from [denovo.me](http://denovo.me). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
