+# Changing the Default *keycloak-subsystem* Configuration
+
+If you need to make a change to the default keycloak-subsystem 
+configuration that is packaged with our distributions, you will need to edit this file:
+https://github.com/keycloak/keycloak/blob/master/wildfly/server-subsystem/src/main/config/default-server-subsys-config.properties
+
+This file contains a single multi-line property containing the subsystem 
+xml declaration.  Maven filtering is used to read this property and 
+inject it everywhere it needs to go.  Editing this file will also take 
+care of propagating it to the distributions like server-dist and demo-dist.
+
+Also, you need to create CLI commands for each change by editing this file:
+https://github.com/keycloak/keycloak/blob/master/wildfly/server-subsystem/src/main/resources/cli/default-keycloak-subsys-config.cli
+
+This CLI snippet is used in the scripts required by the overlay distribution.
+
+## Updating an SPI
+The changes you will likely make are when you need to add a new SPI, change an existing SPI, or add/change a provider within an SPI.
+
+All elements in an SPI declaration are optional, but a full SPI declaration
+  looks like this:
+````xml
+<spi name="dblock">
+     <default-provider>mongo</default-provider>
+     <provider name="jpa" enabled="true">
+         <properties>
+             <property name="lockWaitTimeout" value="800"/>
+         </properties>
+     </provider>
+     <provider name="mongo" enabled="true">
+         <properties>
+             <property name="lockRecheckTime" value="2"/>
+             <property name="lockWaitTimeout" value="600"/>
+         </properties>
+     </provider>
+</spi>
+````
+Here we have two providers defined for the SPI `dblock`.  The 
+`default-provider` is listed as `mongo`.  However it is up to the SPI to decide how it will 
+treat this setting.  Some SPIs allow more than one provider and some do not.  So
+`default-provider` can help the SPI to choose.
+
+Also notice that each provider defines its own set of configuration 
+properties.  The fact that both providers above have a property called 
+`lockWaitTimeout` is just a coincidence.
+
+## Values of type *List*
+The type of each property value is interpreted by the provider. However, 
+there is one exception.  Consider the `jpa` provider for the `eventStore` API:
+````xml
+<spi name="eventsStore">
+     <provider name="jpa" enabled="true">
+         <properties>
+             <property name="exclude-events" value="[&quot;EVENT1&quot;,&quot;EVENT2&quot;]"/>
+         </properties>
+     </provider>
+</spi>
+````
+We see that the value begins and ends with square brackets.  That means that
+the value will be passed to the provider as a list.  In this example, 
+the system will pass the
+provider a list with two element values `EVENT1` and `EVENT2`. To add 
+more values to the list, just separate each list element with a comma. Unfortunately,
+you do need to escape the quotes surrounding each list element with 
+`&quot;`.
