defines BDD acronym, and replaces TDD with BDD

Browse Source 
I think BDD was meant instead of TDD.  I don't see anything about Test-Driven Development further down the documentation.  
Also, the acronym BDD might be obvious to some, but I had to look it up while reading.

Sections can be nested to an arbitrary depth (limited only by your stack size). Each leaf section (i.e. a section that contains no nested sections) will be executed exactly once, on a separate path of execution from any other leaf section (so no leaf section can interfere with another). A failure in a parent section will prevent nested sections from running - but then that's the idea. Sections can be nested to an arbitrary depth (limited only by your stack size).

## BDD-Style ## BDD-Style (Behaviour Driven Development)
If you name your test cases and sections appropriately you can achieve a BDD-style specification structure. This became such a useful way of working that first class support has been added to Catch. Scenarios can be specified using ```SCENARIO```, ```GIVEN```, ```WHEN``` and ```THEN``` macros, which map on to ```TEST_CASE```s and ```SECTION```s, respectively. For more details see [Test cases and sections](test-cases-and-sections.md). If you name your test cases and sections appropriately you can achieve a BDD-style specification structure.
