 # Container Configuration file
 
 The container's top-level directory MUST contain a configuration file called `config.json`.
-The canonical schema is defined in this document, but there is a JSON Schema in [`schema/schema.json`](schema/schema.json) and Go bindings in [`specs-go/config.go`](specs-go/config.go).
+The canonical schema is defined in this document, but there is a JSON Schema in [`schema/config-schema.json`](schema/config-schema.json) and Go bindings in [`specs-go/config.go`](specs-go/config.go).

 This includes the process to run, environment variables to inject, sandboxing features to use, etc.
