@@ -503,22 +479,36 @@ q: How does it work?

 a: The TwelveMonkeys ImageIO project contains plug-ins for ImageIO. ImageIO uses a service lookup mechanism, to discover plug-ins at runtime.

+All you have to do, is to make sure you have the TwelveMonkeys ImageIO JARs in your classpath.

 You can read more about the registry and the lookup mechanism in the [IIORegistry API doc](https://docs.oracle.com/javase/7/docs/api/javax/imageio/spi/IIORegistry.html).

 The fine print: The TwelveMonkeys service providers for JPEG, BMP and TIFF, overrides the onRegistration method, and
 utilizes the pairwise partial ordering mechanism of the `IIOServiceRegistry` to make sure it is installed before
-the Sun/Oracle provided `JPEGImageReader` and `BMPImageReader`, and the Apple provided `TIFFImageReader` on OS X, 
+the Sun/Oracle provided `JPEGImageReader`, `BMPImageReader` `TIFFImageReader`, and the Apple provided `TIFFImageReader` on OS X, 
 respectively. Using the pairwise ordering will not remove any functionality form these implementations, but in most 
 cases you'll end up using the TwelveMonkeys plug-ins instead.

 q: Why is there no support for common formats like GIF or PNG?

-a: The short answer is simply that the built-in support in ImageIO for these formats are good enough as-is.
+a: The short answer is simply that the built-in support in ImageIO for these formats are considered good enough as-is.
 If you are looking for better PNG write performance on Java 7 and 8, see [JDK9 PNG Writer Backport](https://github.com/gredler/jdk9-png-writer-backport).


+q: When is the next release? What is the current release schedule?
+
+a: The goal is to make monthly releases, containing bug fixes and minor new features. 
+And quarterly releases with more "major" features.
+
+
+q: I love this project! How can I help?
+
+a: Have a look at the open issues, and see if there are any issues you can help fix, or provide sample file or create test cases for.
+It is also possible for you or your organization to become a sponsor, through GitHub Sponsors. 
+Providing funding will allow us to spend more time on fixing bugs and implementing new features. 
+

 q: What about JAI? Several of the formats are already supported by JAI.
