-## How this crate differs from [`http-stream`][http-stream]
+## How this crate differs from [`http-cache`][http-cache]
+
+The [`http-cache`][http-cache] crate is a highly-configurable HTTP cache that
+supports different storage backends and middleware for many popular Rust HTTP
+client APIs.
+
+The `http-cache-stream` crate is inspired by the implementation provided by
+`http-cache`, but differs in significant ways:
+
+* `http-cache-stream` supports streaming of requests/responses and does not
+  read a response body into memory to store in the cache.
+* The default storage implementation for `http-cache-stream` uses advisory file
+  locking to coordinate access to storage across multiple processes and threads.
+* The default storage implementation is simple and provides no integrity of
+  cached bodies, but does provide some fault tolerance for writes to cache
+  storage (i.e. partially written cache entries are discarded).
+* The API for `http-cache-stream` is not nearly as configurable as `http-cache`.
+* Only a middleware implementation for `reqwest` will be made initially.
