+## Mix tasks
+
+A separate mix task to register a specific schema or all found schemas in
+schemas folder (see [configuration](#configuration) section) is available
+since [v0.12.0](https://github.com/Strech/avrora/releases/tag/v0.12.0).
+
+For instance if you configure Avrora schemas folder to be at `./priv/schemas`
+and you want to register a schema `io/confluent/Payment.avsc` then you can use
+this command
+
+```console
+$ mix avrora.reg.schema --name io.confluent.Payment
+schema `io.confluent.Payment` will be registered
+```
+
+**NOTE:** It will search for schema `./priv/schemas/io/confluent/Payment.avsc`
+
+If you would like to register all schemas found under `./priv/schemas` then you
+can simply execute this command
+
+```console
+$ mix avrora.reg.schema --all
+schema `io.confluent.Payment` will be registered
+schema `io.confluent.Wrong' will be skipped due to an error `argument error'
+```
