-## API
+## Usage
 
-All functions and attributes that are meant for use by you do not have `_` before their name
-and are also listed before any internal function.
+Use the `XML.parse_[buffer|string|file]` functions to parse XML into an `XMLDocument`, then use `XMLDocument.root`
+to get the root `XMLNode`, from which point use `XMLNode`'s properties to inspect a node and use the `XMLNode.dump_[buffer|string|file|]`
+functions to convert a node back into XML. It's that simple!
 
-All other functions and attributes are **not meant** to be used by you, though of course
-you can edit them as you like.
+## Version Guarantees
+
+All functions and attributes that are meant for use by you do not start with an `_` and are governed by the usual
+SemVer rules. Accordingly, all functions and attributes that *do* start with an `_`  are **not meant** to be used
+by you (and can change or be removed entirely even in patch versions, although that's usually not the case). If you
+*really* need to use something that is currently "private", open an issue and let's talk!
