 //! # Ecosystem
 //!
-//! The testcontainers ecosystem is split into multiple crates, however, the `testcontainers` crate itself is a meta-crate, re-exporting the others. Usually, depending on `testcontainers` should be sufficient for most users needs.
-//! However, ready-to-use images are supplied separately: [`testcontainers-modules`]
+//! `testcontainers` is the core crate that provides an API for working with containers in a test environment.
+//!  However, it does not provide ready-to-use modules, you can implement your [`Image`]s using the library directly or use community supported [`testcontainers-modules`].
