-## Activating the Module
+## Prerequisites
+Ensure you have at least JDK 11 installed.
+Your shell is located at the `quarkus` submodule. (`cd quarkus`)
 
-When build from the project root directory, this module is only enabled if the installed JDK is 11 or newer. 
+### Activating the Module from the root directory

-## Building
+## Building the project the first time
 
-Ensure you have JDK 11 (or newer) installed.
+To build this module and produce the artifacts to run a server, you first need to build the main codebase once. This step will put required modules of keycloak into your local maven cache in package `org.keycloak`:
-
-To build the module and produce the artifacts to run a server:
 
     mvn -f ../pom.xml clean install -DskipTestsuite -DskipExamples -DskipTests
 
-### Building the Distribution
+This build can take some time, usually around two to four minutes depending on your hardware, and even longer depending on the maven packages that need to be downloaded and installed to the cache.
 
-To build the module as well as the distribution packages:
+## Building the Keycloak Quarkus distribution
 
-    mvn -f ../pom.xml clean install -DskipTestsuite -DskipExamples -DskipTests -Pdistribution
+After the main codebase is built, you can build the quarkus distribution, including the zip and tar.gz files, by invoking the following command:
     
-The distribution packages (ZIP and TAR) should be available at [../distribution/server-x-dist](../distribution/server-x-dist/target).
+    mvn clean install -DskipTests
 
-Alternatively, you can also build the distribution directly by running the following command:
+This command produces the distribution artifacts as ZIP and TAR file. The artifacts for the quarkus distribution will be available at the `/dist/target` subdirectory afterwards.
 
-    mvn -f ../distribution/server-x-dist/pom.xml clean install
+As an alternative, you can build the distribution artifacts directly without a rebuild of the code by running the following command:
 
-## Running
+    mvn -f dist/pom.xml clean install
 
-By default, the HTTP port is disabled and you need to provide the key material to configure HTTPS. If you want to enable
+## Running in Keycloak development mode
-the HTTP port, run the server in development mode as follows:
+When you start Keycloak in production mode, the HTTP port is disabled by default, and you need to provide the key material to configure HTTPS, a hostname and other configuration suitable for production. 
+
+For development purposes, you can run the server in development mode instead using `start-dev`:
 
     java -jar server/target/lib/quarkus-run.jar start-dev
 
+This spins up Keycloak using a development database (h2-file) and with insecure HTTP enabled.
+
+### Running from your IDE
+Alternatively, you can run the server in development mode from your IDE. For that, run the `org.keycloak.quarkus._private.IDELauncher` main class in the `server` directory.
+
 ## Contributing
+Please make sure to read our [Contribution Guidelines](../CONTRIBUTING.md) before contributing.
 
-### Development Mode
+To run the server in Quarkus' development mode, invoke the following command:
-
-To run the server in development mode:
 
     mvn -f server/pom.xml compile quarkus:dev -Dquarkus.args="start-dev"
 
-You should be able to attach your debugger to port `5005`.
+You will be able to attach your debugger to port `5005`.

+For debugging the build steps right after start, you can suspend the JVM by running:
 
     mvn -f server/pom.xml -Dsuspend=true compile quarkus:dev -Dquarkus.args="start-dev"
 
-When running using `quarkus:dev` you should be able to do live coding whenever code changes within the `server` module. Changes you make to transient dependencies from the server extension (e.g: services, model, etc) won't be reflected into the running server. However, you can still leverage the hot swapping capabilities from your IDE to make changes at runtime.
+When running using `quarkus:dev` you are able to do live coding whenever you change / add code in the `server` module, for example when creating a new custom provider.

+There are currently limitations when running in development mode that block us to use all capabilities the Quarkus development mode has to offer. For instance, hot-reload of transient dependencies from keycloak (e.g.: keycloak-* dependencies) do not work.

-blocks us to leverage all the capabilities from Quarkus dev mode. For instance, hot-reload of transient dependencies from the server extension (e.g.: keycloak-* dependencies) does not work. More improvements should be expected to improve the experience.
 
-NOTE: When developing custom providers, you should be able to benefit from live coding as long as you keep changes within the `server` module. 
+## Running tests
+Keycloaks Quarkus distribution module uses a new testsuite more integrated into the quarkus platform.
 
-Alternatively, you can run the server in development mode from your IDE. For that, run the `org.keycloak.quarkus._private.IDELauncher` main class.
+### Running tests from your IDE
+The tests can also be run from an IDE GUI such as Intellij IDEA. There are different kinds of tests:
+* Unit tests: Located in the respective module (`deployment`, `runtime`)
+* Integration tests:
+  * `@CLITest` annotated: These tests have no prerequisites and are whitebox tests, so you can easily debug them.
+  * `@DistributionTest` annotated: These tests need a build of the distribution artifacts first to run. These are blackbox tests, so not as easily debuggable as `@CLITest` annotated tests. Mostly used for scenarios when a `build` is involved or build options need to change, as this invocation happens in a different JVM.
+
+### Running container-based tests
+The `@DistributionTest` annotated tests can use different runtimes, e.g. plain JVM or a docker container. Per default, they use the plain JVM mode. 
+
+To run them from a container image instead, you need to build the distribution first. Then you can use the flag `-Dkc.quarkus.tests.dist=docker`. This builds a docker image from the provided distribution archives and runs the `@DistributionTest` annotated tests for them.
+
+There are some tests annotated `@RawDistOnly` which prevents them from running in docker. You'll find a short reason in the respective annotation.
+
+The container based tests are using Testcontainers to spin up the container image and can be considered tech preview.
+
+### Running database tests
+There are also some container based tests to check if Keycloak starts using one of the supported database vendors. They are annotated with `@WithDatabase`. 
+
+These tests are disabled by default. They using Quarkus development mode predefined database containers by default and can be run in the `tests` subdirectory by using e.g. 
+
+    mvn clean install -Dkc.test.storage.database=true -Dtest=MariaDBStartDatabaseTest
+
+to spin up a MariaDB container and start Keycloak with it.
