 This is the Plain Text Accounting Cookbook,
-a sort of site map for plaintextaccounting.org.
+a place to collect additional practical-minded PTA docs aimed at getting useful things done,
+often not app-specific.
 If you don't see what you need, ask for it in the 
 [[index#news-discussion|chat]] and we'll add it, or you can
 [add it yourself](https://github.com/plaintextaccounting/plaintextaccounting/blob/master/src/Cookbook.md).
