+## Building & Running
+
+To build or run the project, use one of the following tasks:
+
+| Task                                    | Description                                                          |
+| -----------------------------------------|---------------------------------------------------------------------- |
+| `./gradlew test`                        | Run the tests                                                        |
+| `./gradlew build`                       | Build everything                                                     |
+| `./gradlew buildFatJar`                 | Build an executable JAR of the server with all dependencies included |
+| `./gradlew buildImage`                  | Build the docker image to use with the fat JAR                       |
+| `./gradlew publishImageToLocalRegistry` | Publish the docker image locally                                     |
+| `./gradlew run`                         | Run the server                                                       |
+| `./gradlew runDocker`                   | Run using the local docker image                                     |
+
+If the server starts successfully, you'll see the following output:
+
+```
+2024-12-04 14:32:45.584 [main] INFO  Application - Application started in 0.303 seconds.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
