 ### OCI Container JSON Format:
 
-Below are sample `config.json` and `runtime.json` configuration files. It assumes that
-the file-system is found in a directory called `rootfs` and there is a
-user with uid and gid of `0` defined within that file-system.
+OCI container JSON format is based on OCI [specs](https://github.com/opencontainers/specs).
+You can generate JSON files by using `runc spec`, it'll generate `config.json`
+and `runtime.json`. It assumes that the file-system is found in a directory called
+`rootfs` and there is a user with uid and gid of `0` defined within that file-system.

+Below are sample `config.json` and `runtime.json` configuration files. Note that it
+could be outdated, please always create base JSON files by `runc spec`.
