+Installation information
+=======
+
+This template repository can be directly cloned to get you started with a new
+mod. Simply create a new repository cloned from this one, by following the
+instructions provided by [GitHub](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template).
+
+Once you have your clone, simply open the repository in the IDE of your choice. The usual recommendation for an IDE is either IntelliJ IDEA or Eclipse.
+
+If at any point you are missing libraries in your IDE, or you've run into problems you can
+run `gradlew --refresh-dependencies` to refresh the local cache. `gradlew clean` to reset everything 
+{this does not affect your code} and then start the process again.
+
+Mapping Names:
+============
+By default, the MDK is configured to use the official mapping names from Mojang for methods and fields 
+in the Minecraft codebase. These names are covered by a specific license. All modders should be aware of this
+license. For the latest license text, refer to the mapping file itself, or the reference copy here:
+https://github.com/NeoForged/NeoForm/blob/main/Mojang.md

+#   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
