+**Version information**
+1. The version of the TwelveMonkeys ImageIO library in use.
+For example:  4.0.0
+
+2. The *exact* output of `java --version` (or `java -version` for older Java releases). 
+For example: 
+
+    java version "1.8.0_271"
+    Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
+    Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)
+
+3. Extra information about OS version, server version, standalone program or web application packaging, executable wrapper, etc. Please state exact version numbers where applicable.
+
+**To Reproduce**
+Steps to reproduce the behavior:
+
+1. Compile the below sample code
+2. Download the sample image file
+3. Run the code with the sample file
+4. See error
+
+**Expected behavior**
+A clear and concise description of what you expected to happen.
+
+**Example code**
+Preferably as a failing JUnit test, or a standalone program with a `main` method that showcases the problem. 
+
+Less is more. Don't add your entire project, only the code required to reproduce the problem. 😀 
+
+**Sample file(s)**
+Attach any sample files needed to reproduce the problem. Use a ZIP-file if the format is not directly supported by GitHub.

 ## About

-TwelveMonkeys ImageIO is a collection of plugins and extensions for Java's ImageIO.
+TwelveMonkeys ImageIO provides extended image file format support for the Java platform, through plugins for the `javax.imageio.*` package.

-These plugins extend the number of image file formats supported in Java, using the `javax.imageio.*` package.
-The main purpose of this project is to provide support for formats not covered by the JRE itself.
-
-Support for formats is important, both to be able to read data found
+The main goal of this project is to provide support for formats not covered by the JRE itself. 
+Support for these formats is important, to be able to read data found
 "in the wild", as well as to maintain access to data in legacy formats.
-Because there is lots of legacy data out there, we see the need for open implementations of readers for popular formats.
-The goal is to create a set of efficient and robust ImageIO plug-ins, that can be distributed independently.
+As there is lots of legacy data out there, we see the need for open implementations of readers for popular formats.

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

-a: While JAI (and jai-imageio in particular) have support for some of the formats, JAI has some major issues.
+a: While JAI (and jai-imageio in particular) have support for some of the same formats, JAI has some major issues.
 The most obvious being:
 - It's not actively developed. No issues has been fixed for years.
 - To get full format support, you need native libs.
