+Check the xref:user-guide/index.adoc[User guide] for more information about writing Camel Quarkus applications.
+
+== 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 https://tika.apache.org/1.24.1/formats.html[Tika parsers] in JVM mode,
+only some of those are supported in native mode - see the https://quarkus.io/guides/tika[Quarkus Tika guide].
+
+Use of the Tika parser without any configuration will initialize all available parsers. Unfortunately as some of them
+don't work in the native mode, the whole execution will fail.
+
+In order to make the Tika parser work in the native mode, selection of parsers for initialization should be used.
+
+* `quarkus.tika.parsers` Comma separated list of parsers (abbreviations). There are two predefined parsers:
+`pdf` and `odf`.
+* `quarkus.tika.parser.*` Adds new parser abbreviation to be used with previous property. Value is the full class of
+the parser.
+
+Example of `application.properties`:
+[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 the https://quarkus.io/guides/tika[Quarkus Tika guide].
