-# code-with-quarkus
+# Quarkus example
 
-This project uses Quarkus, the Supersonic Subatomic Java Framework.
+Dit project gebruikt Quarkus: <https://quarkus.io/>, een Java framework waarmee onder andere API's kunnen worden gebruikt.
 
-If you want to learn more about Quarkus, please visit its website: <https://quarkus.io/>.
-
-## Running the application in dev mode
-
-You can run your application in dev mode that enables live coding using:
-
-```shell script
-./mvnw quarkus:dev
-```
-
-> **_NOTE:_**  Quarkus now ships with a Dev UI, which is available in dev mode only at <http://localhost:8080/q/dev/>.
-
-## Packaging and running the application
-
-The application can be packaged using:
+Om het project te bouwen en een `openapi.json` te genereren, run het volgende:
 
 ```shell script
 ./mvnw package
 ```
 
-It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory.
-Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory.
-
-The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.
-
-If you want to build an _über-jar_, execute the following command:
-
-```shell script
-./mvnw package -Dquarkus.package.jar.type=uber-jar
-```
-
-The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.
-
-## Creating a native executable
-
-You can create a native executable using:
-
-```shell script
-./mvnw package -Dnative
-```
-
-Or, if you don't have GraalVM installed, you can run the native executable build in a container using:
-
-```shell script
-./mvnw package -Dnative -Dquarkus.native.container-build=true
-```
-
-You can then execute your native executable with: `./target/code-with-quarkus-1.0.0-SNAPSHOT-runner`
-
-If you want to learn more about building native executables, please consult <https://quarkus.io/guides/maven-tooling>.
-
-## Provided Code
-
-### REST
-
-Easily start your REST Web Services
+Dit genereert `target/generated/openapi/openapi.json` op basis van de classes in [`src/main/java/org/acme/`](src/main/java/org/acme/).
+Daar kun je de verscheidene annotations bekijken die gebruikt worden om API's te documenteren.
+Tevens is er enkele configuratie vereist in [`src/main/resources/application.properties`](src/main/resources/application.properties) om Quarkus goed in te stellen.
 
-[Related guide section...](https://quarkus.io/guides/getting-started-reactive#reactive-jax-rs-resources)
+Met deze annotations en configuratie voldoet het example aan alle regels van de API Design Rules.

-# This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode
-#
-# Before building the container image run:
-#
-# ./mvnw package
-#
-# Then, build the image with:
-#
-# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/code-with-quarkus-jvm .
-#
-# Then run the container using:
-#
-# docker run -i --rm -p 8080:8080 quarkus/code-with-quarkus-jvm
-#
-# If you want to include the debug port into your docker image
-# you will have to expose the debug port (default 5005 being the default) like this :  EXPOSE 8080 5005.
-# Additionally you will have to set -e JAVA_DEBUG=true and -e JAVA_DEBUG_PORT=*:5005
-# when running the container
-#
-# Then run the container using :
-#
-# docker run -i --rm -p 8080:8080 quarkus/code-with-quarkus-jvm
-#
-# This image uses the `run-java.sh` script to run the application.
-# This scripts computes the command line to execute your Java application, and
-# includes memory/GC tuning.
-# You can configure the behavior using the following environment properties:
-# - JAVA_OPTS: JVM options passed to the `java` command (example: "-verbose:class") - Be aware that this will override
-# the default JVM options, use `JAVA_OPTS_APPEND` to append options
-# - JAVA_OPTS_APPEND: User specified Java options to be appended to generated options
-#   in JAVA_OPTS (example: "-Dsome.property=foo")
-# - JAVA_MAX_MEM_RATIO: Is used when no `-Xmx` option is given in JAVA_OPTS. This is
-#   used to calculate a default maximal heap memory based on a containers restriction.
-#   If used in a container without any memory constraints for the container then this
-#   option has no effect. If there is a memory constraint then `-Xmx` is set to a ratio
-#   of the container available memory as set here. The default is `50` which means 50%
-#   of the available memory is used as an upper boundary. You can skip this mechanism by
-#   setting this value to `0` in which case no `-Xmx` option is added.
-# - JAVA_INITIAL_MEM_RATIO: Is used when no `-Xms` option is given in JAVA_OPTS. This
-#   is used to calculate a default initial heap memory based on the maximum heap memory.
-#   If used in a container without any memory constraints for the container then this
-#   option has no effect. If there is a memory constraint then `-Xms` is set to a ratio
-#   of the `-Xmx` memory as set here. The default is `25` which means 25% of the `-Xmx`
-#   is used as the initial heap size. You can skip this mechanism by setting this value
-#   to `0` in which case no `-Xms` option is added (example: "25")
-# - JAVA_MAX_INITIAL_MEM: Is used when no `-Xms` option is given in JAVA_OPTS.
-#   This is used to calculate the maximum value of the initial heap memory. If used in
-#   a container without any memory constraints for the container then this option has
-#   no effect. If there is a memory constraint then `-Xms` is limited to the value set
-#   here. The default is 4096MB which means the calculated value of `-Xms` never will
-#   be greater than 4096MB. The value of this variable is expressed in MB (example: "4096")
-# - JAVA_DIAGNOSTICS: Set this to get some diagnostics information to standard output
-#   when things are happening. This option, if set to true, will set
-#  `-XX:+UnlockDiagnosticVMOptions`. Disabled by default (example: "true").
-# - JAVA_DEBUG: If set remote debugging will be switched on. Disabled by default (example:
-#    true").
-# - JAVA_DEBUG_PORT: Port used for remote debugging. Defaults to 5005 (example: "8787").
-# - CONTAINER_CORE_LIMIT: A calculated core limit as described in
-#   https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt. (example: "2")
-# - CONTAINER_MAX_MEMORY: Memory limit given to the container (example: "1024").
-# - GC_MIN_HEAP_FREE_RATIO: Minimum percentage of heap free after GC to avoid expansion.
-#   (example: "20")
-# - GC_MAX_HEAP_FREE_RATIO: Maximum percentage of heap free after GC to avoid shrinking.
-#   (example: "40")
-# - GC_TIME_RATIO: Specifies the ratio of the time spent outside the garbage collection.
-#   (example: "4")
-# - GC_ADAPTIVE_SIZE_POLICY_WEIGHT: The weighting given to the current GC time versus
-#   previous GC times. (example: "90")
-# - GC_METASPACE_SIZE: The initial metaspace size. (example: "20")
-# - GC_MAX_METASPACE_SIZE: The maximum metaspace size. (example: "100")
-# - GC_CONTAINER_OPTIONS: Specify Java GC to use. The value of this variable should
-#   contain the necessary JRE command-line options to specify the required GC, which
-#   will override the default of `-XX:+UseParallelGC` (example: -XX:+UseG1GC).
-# - HTTPS_PROXY: The location of the https proxy. (example: "myuser@127.0.0.1:8080")
-# - HTTP_PROXY: The location of the http proxy. (example: "myuser@127.0.0.1:8080")
-# - NO_PROXY: A comma separated lists of hosts, IP addresses or domains that can be
-#   accessed directly. (example: "foo.example.com,bar.example.com")
