-## Disclaimer
+## About the data
 
-This library is still in development phase and is not recommended for production use.
+Besides a couple of builtin types, coredumpy treats almost every object as an
+Python object with attributes, and that's what it records in the dump.
 
-The APIs could change during development phase.
+It does not use `pickle` so you don't need to have the same run-time environment
+when you load the dump. It's also safer to open an arbitrary dump without the
+unsafe pickling process.
+
+That being said, most of the objects will not be "restored" as they were when
+being dumped. You are in an observer mode where you can inspect attributes of
+all objects. None of the methods of the objects would work, nor would any
+dymanic features.
