+# How to use failure
+
+This section of the documentation is about how the APIs exposed in failure can
+be used. It is organized around the major APIs of failure:
+
+- **[The Fail trait](./fail.md):** The primary abstraction provided by failure.
+- **[Deriving Fail](./derive-fail.md):** A custom derive for the Fail trait.
+- **[The Error type](./error.md):** A convenient wrapper around any Fail type.
