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).
