+# Adapter SPI
+
+This module is primarily used for custom adapters in the testsuite.
+
+## Undertow
+Modules related to Undertow:
+* Keycloak Undertow Adapter SPI (`undertow-adapter-spi-jakarta`)
+* Keycloak Undertow OIDC adapter (`undertow-adapter-jakarta`)
+* Keycloak Undertow SAML adapter (`undertow-adapter-saml-jakarta`)
+
+These modules are automatically generated from the Keycloak adapters module (`/adapters`) and converted to adapters supporting JakartaEE.
+
+You can override files from the original module by putting the class with the same name into the `src` directory.
+Do not forget to edit `.gitignore` file for changes, which should be kept in the module.
+
+You can check the behavior in `undertow-adapter-spi-jakarta` module and class `UndertowHttpServletRequest`.
