updating docs (#695)

Tried to make the ABOUT.md a bit more appealing - these days no one reads long paragraphs anymore :-( Added some context to LEARNING.md and RESSOURCES.md
included e.g. Java script in the Nutshell links

 # About
 
-Raku (formerly known as Perl 6) is a clean, modern, multi-paradigm language; it offers procedural, object-oriented AND functional programming methodologies.
-It is a supremely flexible language, adapting to your style of programming, whether that be quick one­liners for sysadmins, scripts to manage a database import, or the full stack of modules necessary to realise an entire website.
+It may be difficult to find a programming language that is more expressive. [Raku](https://raku.org/) is a modern, multi-paradigm language. Raku offers [procedural](https://docs.raku.org/language/functions), [object-oriented](https://docs.raku.org/language/objects) and [functional programming](https://docs.raku.org/language/functions#Functions_are_first-class_objects) methodologies.
 
-Raku enhances Perl’s long­term appeal with a proper object system including roles, threading and multi­method dispatch.
-It has spent a long time coming to fruition and has learned from other programming languages, building on their success and learning from the issues of the past.
-We believe Raku is a language that will last for decades as it has been conceived to adapt to future trends and is flexible in its usage with other languages.
+[Curious?](https://raku.org/) Dig deeper in the [documentation](https://docs.raku.org/) or the module [repository](https://raku.land/) (like pypi or CPAN).
 
-Raku learns from other languages.
-For instance: taking threading from Java (simplified to a handful of methods); Foreign-function interfaces from Lisp make accessing libraries as simple as one line of code.
-Regular expressions are now turned up to 11 with the introduction of Parser Expression Grammars, which let you tackle huge parsing tasks.
-Strictures and warnings are now automatic, cutting out huge swathes of potential errors.
+It is a supremely [flexible](https://docs.raku.org/language/operators) language, [adapting](https://docs.raku.org/language/glossary#gradual_typing) to your style of programming, whether that be quick [one­liners](https://docs.raku.org/language/create-cli) for sysadmins, scripts to manage a database import, or the full stack of modules necessary to realise an [entire website](https://cro.services/).
 
-Raku’s mottos remain the same as Perl:
-“Perl is different. In a nutshell, Perl is designed to make the easy jobs easy, without making the hard jobs impossible.” and “There Is More Than One Way To Do It”.
-Now with even more -Ofun (optimized for fun) added.
+Raku learns from other languages:
+
+* It enhances Perl’s long­term appeal with a proper object system including [roles](https://docs.raku.org/language/typesystem#role), [threading](https://docs.raku.org/language/concurrency) and [multi­method](https://docs.raku.org/language/glossary#Multi-dispatch) dispatch.
+* It's taking threading from Java - [simplified](https://docs.raku.org/language/concurrency) to a handful of methods.
+* Using [foreign-function](https://docs.raku.org/language/nativecall) interfaces from Lisp makes accessing libraries as simple as one line of code.
+* [Regular expressions](https://docs.raku.org/language/regexes) are now turned up to 11 - with the introduction of Parser Expression [Grammars](https://docs.raku.org/language/grammars), which let you tackle huge parsing tasks.
+* Strictures and warnings are now automatic, cutting out huge swathes of potential errors.
+* ... and it knows how to do [math](https://docs.raku.org/language/math): ```1/10 * 3 == 0.3 ``` - try that in your favorite language!
