+# ViaLegacy
+ViaVersion addon to add support for EVERY minecraft server version (Classic, Alpha, Beta, Release, April Fools).
+
+## Supported Server versions
+- Classic (c0.0.15 - c0.30 including [CPE](https://wiki.vg/Classic_Protocol_Extension))
+- Alpha (a1.0.15 - a1.2.6)
+- Beta (b1.0 - b1.8.1)
+- Release (1.0.0 - 1.7.10)
+- April Fools (3D Shareware, 20w14infinite)
+- Combat Snapshots (Combat Test 8c)
+
+## Releases
+### Gradle/Maven
+To use ViaLegacy with Gradle/Maven you can use this [Maven server](https://maven.lenni0451.net/#/releases/net/raphimc/ViaLegacy) or [Jitpack](https://jitpack.io/#RaphiMC/ViaLegacy).  
+You can also find instructions how to implement it into your build script there.
+
+### Jar File
+If you just want the latest jar file you can download it from this [Jenkins](https://build.lenni0451.net/job/ViaLegacy/).
+
+## Usage
+TODO

+#
+#   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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
