-Currently available in Java, JavaScript, Dart, C++, C#, Objective C, Lua and Python.
-Regardless of language, each library features the same API and the same functionality.
-All versions also have comprehensive test harnesses.
+Originally built in 2006 to power Google Docs, this library is now available in C++, C#, Dart, Java, JavaScript, Lua, Objective C, and Python.

+### Reference
+
+* [API](https://github.com/google/diff-match-patch/wiki/API) - Common API across all languages.
+* [Line or Word Diffs](https://github.com/google/diff-match-patch/wiki/Line-or-Word-Diffs) - Less detailed diffs.
+* [Plain Text vs. Structured Content](https://github.com/google/diff-match-patch/wiki/Plain-Text-vs.-Structured-Content) - How to deal with data like XML.
+* [Unidiff](https://github.com/google/diff-match-patch/wiki/Unidiff) - The patch serialization format.
+* [Support](https://groups.google.com/forum/#!forum/diff-match-patch) - Newsgroup for developers.
+
+### Languages
+Although each language port of Diff Match Patch uses the same API, there are some language-specific notes.
+
+* C++
+* [C#](https://github.com/google/diff-match-patch/wiki/Language:-C%23)
+* [Dart](https://github.com/google/diff-match-patch/wiki/Language:-Dart)
+* [Java](https://github.com/google/diff-match-patch/wiki/Language:-Java)
+* [JavaScript](https://github.com/google/diff-match-patch/wiki/Language:-JavaScript)
+* [Lua](https://github.com/google/diff-match-patch/wiki/Language:-Lua)
+* Objective-C

+A standardized speed test tracks the [relative performance of diffs](https://docs.google.com/spreadsheets/d/1zpZccuBpjMZTvL1nGDMKJc7rWL_m_drF4XKOJvB27Kc/edit#gid=0) in each language.
 
 ### Algorithms
 This library implements [Myer's diff algorithm](https://neil.fraser.name/writing/diff/myers.pdf) which is generally considered to be the best general-purpose diff. A layer of [pre-diff speedups and post-diff cleanups](https://neil.fraser.name/writing/diff/) surround the diff algorithm, improving both performance and output quality.
