We apologize in advance for any bugs. Please take the time to open an issue about your problem. Include your CPU / operating system, the command you tried to run, and all the output to your terminal.
We're very excited you're interested in Rubinius. What started as a toy grew into a labour of love. We love building Rubinius and hope you'll love using it. We need your feedback to make Rubinius the best it can be. You can reach us in the IRC channel at #rubinius on freenode.net, via Twitter or on the mailing list.

Rubinius High Level Overview
Rubinius is software that translates the code for the Ruby programming language such as
puts "hello world"
and turns it into effecient machine code like this
push %rbp; mov %rsp, %rbp; push %rbx; subq $0x98, %rsp; cmp $0x0, 0x10(%rcx); call 0xffffffffff472010; jmp 0x9c; …
then executes it.
A large aspect of popular languages such as C and Java is that the majority of the functionality available to the programmer is written in the language itself. Rubinius has the goal of adding Ruby to that list. Rubyists could more easily add features to the language, fix bugs, and learn how the language works. Wherever possible Rubinius is written in Ruby. Where not possible (yet), it's C++.
Rubinius is an implementation of the Ruby programming language.
The Rubinius bytecode virtual machine is written in C++, incorporating LLVM to compile bytecode to machine code at runtime. The bytecode compiler and vast majority of the core classes are written in pure Ruby.
To interact with the rest of the system, the VM provides primitives which can be attached to methods and invoked. Additionally, FFI is provides a direct call path to most C functions.
Rubinius uses a precise, compacting, generational garbage collector. It includes a compatible C-API for C extensions written for the standard Ruby interpreter (often referred to as MRI—Matz's Ruby Implementation).

The Rubinius Nitty Gritty
From the start, compatibility has been critical to us. To that end, we created the RubySpec to ensure that we maintained parity with official Ruby. We are currently at a 93% RubySpec pass rate and growing everyday.
For now Rubinius is targeting MRI 1.8.7 (1.9 is on the post 1.0 list). Most Gems, Rails plugins and C-Extensions work right out of the box. If you find a bug, let us know and we'll get on top of it.
Rubinius is not without its flaws. Namely, ObjectSpace#_id2ref, ObjectSpace#each_object(limited) and callcc don't work. At least, Not yet.
