+
+== Camel Quarkus limitations
+
+Parameters `tikaConfig` and `tikaConfigUri` are not available in quarkus camel tika extension. Configuration
+can be changed only via `application.properties`.
+
+While you can use any of the available Tika parsers in JVM mode (https://tika.apache.org/[Apache Tika]),
+only several Tika parses are supported in native mode. See https://quarkus.io/guides/tika[QUARKUS - USING APACHE TIKA].
+
+In order to work in native mode, some properties should be set:
+
+* `quarkus.tika.parsers`
+* optionally `quarkus.tika.parser.*`
+
+Example of `application.properties` follows :
+[source,properties]
+----
+quarkus.tika.parsers = pdf,odf,office
+quarkus.tika.parser.office = org.apache.tika.parser.microsoft.OfficeParser
+----
+
+For more information about selecting parsers see https://quarkus.io/guides/tika[QUARKUS - USING APACHE TIKA]
