+|amongoc| Features
+##################
+
+|amongoc| is the first official asynchronous MongoDB C driver library, and
+targets compatibility with the driver library APIs that are common across other
+language implementations.
+
+Because the library needs to be built from the ground-up to support asynchronous
+control flow, very little of the existing C driver implementation can be used
+directly, meaning that much of the feature set needs to be reimplemented. This
+page documents the status of the common driver library APIs within |amongoc|.
+Since the library is a proof-of-concept, many features have no target release
+date, but may be added in some future production-ready version.
