 ### Virtual schema http/FileSystem
 
-The `oci-image-tool` uses a virtual [http/FileSystem](https://golang.org/pkg/net/http/#FileSystem) to load the JSON schema files for validating OCI images and/or manifests. The virtual file system is generated using the `esc` tool and compiled into the `oci-image-tool` binary so the JSON schema files don't have to be distributed along with the binary.
