+# Implementation Coverage
+This document attempts to describe the implementation status of Crypto APIs/Interfaces from Node.js in the `react-native-quick-crypto` library.
+
+# `Crypto`
+> TODO
+
+# `SubtleCrypto`
+
+> Note: A lot of isomorphic packages check the availability of `crypto.subtle` and use it instead of `crypto`. Until `crypto.subtle` is feature-complete, you might want to set it to `undefined` so that `crypto` gets used instead for transitive dependencies.
