-### Which edition is right for me?
+Add the following to the `<head>` of your HTML page:
 
-If you're an individual doing personal experiments, a developer of free and open-source software, a student or a researcher, pick the Free Edition. If you're a freelancer, a small game studio, a small marketing or webdesign agency, or a similar business, pick the Professional Edition.

-### Is it free of charge?

-It's free of charge if your software is free.
+MARTINS.js is dual-licensed. It can be used for free under the [AGPL 3.0](./license/agpl-3.0.md). Any software developed with it must be free software. If you're doing personal experiments, or if you're a student, a hobbyist or a developer of free and open-source software, you may use it for free.
 
-The Free Edition is unsuitable for most commercial users. It's [AGPL](./license/agpl-3.0.md)-licensed: any software written with the Free Edition must be free as well. If you write non-free software, use the Professional Edition instead.
-
-You may use the Professional Edition to create various kinds of commercial, proprietary AR experiences. However, you may not sublicense it nor transfer your license to anyone. Additionally, you may not use it to create any product that competes with this software, including a "as-a-service" style of product (e.g., SaaS). Please read the [license](./license/PolyForm-Perimeter-1.0.0-1.md) for more information.

-

-
-2. You'll be able to create WebAR experiences for various kinds of **commercial, closed-source endeavors**.
-
-3. You'll get **a warm feeling of well-being** :heart:{ .heart }, knowing that you are a supporter of an open-source initiative that you care about. I speak [a few words about supporting open-source](#why-support-open-source).
-
-## Why support Open Source?
-
-Open Source is not free. Projects such as this one require significant time, effort and skill from developers - some of them with highly specialized knowledge that you won't easily find in the marketplace. When you support an open-source project, you help its continued development and maintenance. Showing your support is a vital thing to do if the project is valuable to you.
-
-Open Source is linked to the idea of _software freedom_[^1]. More often than not, people who engage in this cause have a desire to serve others. This service, however, must be sustainable. I've seen that, as their projects grow, developers work way too much and receive way too little for their efforts, to the point of unsustainability. Often they have other jobs and find themselves working overtime to maintain their freely available projects and help users with their tickets and requests - all that for no pay. This grossly unbalanced situation causes developer burnout and it's not uncommon to see them drop out of open-source completely or abandon their projects, which is a loss for everyone.
-
-We must collectively aim for a healthy ecosystem that benefits the users and the developers of open-source software. **It's in the best interest of for-profit businesses that derive value from open-source software to support the developers.** Those who derive financial benefit from open-source should give back and support the developers of the projects they rely on, because the risk of not supporting them far exceeds the cost of supporting them. Developers are under no compulsion to do something that doesn't serve them.
-
-Developers such as myself sometimes pick strong copyleft licenses like the AGPL[^2]. If you're going to embed a copyleft-licensed software in your product, then you must make your entire product free and open-source. By doing so, you contribute back to the free and open-source software movement. Alternatively, you may financially support the developers in exchange for a different license that makes no such requirement. We call this _dual-licensing_.
-
-Far from being merely a moral duty, giving back is a necessity. It's a practical matter that helps you, your business, and the developers thrive. It's a key element that helps the open-source projects you rely on be sustainable; so much so that I see a growing trend towards sustainability in the open-source movement. You too can become part of this virtuous cycle. Doing so will ultimately benefit you too.
