+## ~~:plugins:symbol-processor~~
+
+This module holds the KSP plugin, published as the library "symbol-processor-all" that can generate data schemas from 
+a data sample using the `@file:ImportDataSchema` annotation. This annotation can be used as an alternative to
+the `dataframes {}` syntax of the [Gradle plugin](../dataframe-gradle-plugin) that's declared closer to the source code.
+It is also used to detect (both manually written- or generated) `@DataSchema` annotated classes/interfaces to generate
+column accessors for in the form of extension properties.
+
+If you use the [Gradle plugin](../dataframe-gradle-plugin), this module and KSP are added as a dependency automatically.
+
+Read more about how to use this at
+[Data Schemas in Gradle projects](https://kotlin.github.io/dataframe/schemasgradle.html) and 
+[Extension Properties API](https://kotlin.github.io/dataframe/extensionpropertiesapi.html).
+
+### DISABLED!
+
+This plugin is disabled as KSP1 is no longer compatible with Kotlin 2.3+.
+See https://kotlin.github.io/dataframe/gradle-plugin.html.
+The recommended alternative is to use the [Compiler Plugin](https://kotlin.github.io/dataframe/compiler-plugin.html)
+and [generating schemas manually from dataframes in runtime](https://kotlin.github.io/dataframe/dataschemagenerationmethods.html).
