 4. We write our individual test assertions using the REQUIRE macro. Rather than a separate macro for each type of condition we express the condition naturally using C/C++ syntax. Behind the scenes a simple set of expression templates captures the left-hand-side and right-hand-side of the expression so we can display the values in our test report. As we'll see later there _are_ other assertion macros - but because of this technique the number of them is drastically reduced.

-placeholder for "why do we need yet another C++ test framework?"
+Good question. For C++ there are quite a number of established frameworks, including (but not limited to), [CppUnit](http://sourceforge.net/apps/mediawiki/cppunit/index.php?title=Main_Page), [Google Test](http://code.google.com/p/googletest/), [Boost.Test](http://www.boost.org/doc/libs/1_49_0/libs/test/doc/html/index.html), [Aeryn](https://launchpad.net/aeryn), [Cute](http://r2.ifs.hsr.ch/cute), [Fructose](http://fructose.sourceforge.net/) and [many, many more](http://en.wikipedia.org/wiki/List_of_unit_testing_frameworks#C.2B.2B). Even for Objective-C there are a few, including OCUnit - which now comes bundled with XCode.
+
+So what does Catch bring to the party that differentiates it from these? Apart from a Catchy name, of course.
+
+## Key Features
+
+* Really easy to get started. Just download catch.hpp, #include it and you're away. 
+* No external dependencies. As long as you can compile C++98 and have a C++ standard library available.
+* Write test cases as, self-registering, functions or methods.
+* Divide test cases into sections, each of which is run in isolation (eliminates the need for fixtures!)
+* Use BDD-style GIVEN-WHEN-THEN in place of test cases and sections.
+* Only one core assertion macro for comparisons. Standard C/c++ operators are used for the comparison - yet the full expression is decomposed and lhs and rhs values are logged.
+
+## Other core features
+
+* Tests are named using free-form strings - no more couching names in legal identifiers.
+* Tests can be tagged for easily running ad-hoc groups of tests.
+* Failures can (optionally) break into the debugger on Windows and Mac.
+* Output is through modular reporter objects. Basic textual and XML reporters are included. Custom reporters can easily be added.
+* JUnit xml output is supported for integration with third-party tools, such as CI servers.
+* A default main() function is provided (in a header), but you can supply your own for complete control (e.g. integration into your own test runner GUI).
+* A command line parser is provided and can still be used if you choose to provided your own main() function.
+* Catch can test itself.
+* Alternative assertion macro(s) report failures but don't abort the test case
+* Floating point tolerance comparisons are built in using an expressive Approx() syntax.
+* Internal and friendly macros are isolated so name clashes can be managed
+* Support for Matchers (early stages)
+
+## Objective-C-specific features
+
+* Automatically detects if you are using it from an Objective-C project
+* Works with and without ARC with no additional configuration
+* Implement test fixtures using Obj-C classes too (like OCUnit)
+* Additional built in matchers that work with Obj-C types (e.g. string matchers)
