+## Custom configuration schema
+
+EMQX 5.7.0 introduced the Avro configuration schema feature which allows plugins to define their own config schema to be used and managed.  In order to use this feature:
+
+- Be sure to use EMQX 5.7.0 or newer;
+- Rename and edit the following files:
+  - `priv/config.hocon.example` -> `priv/config.hocon`
+  - `priv/config_i18n.json.example` -> `priv/config_i18n.json`
+  - `priv/config_schema.avsc.example` -> `priv/config_schema.avsc`
+    - Refer to `priv/config_schema.avsc.enterprise.example` if using EMQX Enterprise
+      Edition.
+- Set `:with_config_schema?` to `true` under the `emqx_plugin_opts` release config in
+  `mix.exs`.
+- Add `:emqx_plugins` as a dependency by uncommenting the line containing `emqx_dep.(:emqx_plugins)` in `mix.exs`'s dependencies.
