+## Building
+To build you must have several versions of spigot built and inside your maven cache. Here's a list of commands to run to install all of the correct versions:
+```
+java -jar ./BuildTools.jar --rev 1.14.4
+java -jar ./BuildTools.jar --rev 1.15
+java -jar ./BuildTools.jar --rev 1.16.1
+java -jar ./BuildTools.jar --rev 1.16.3
+java -jar ./BuildTools.jar --rev 1.16.5
+java -jar ./BuildTools.jar --rev 1.17 --remapped remapped-mojang
+java -jar ./BuildTools.jar --rev 1.17.1 --remapped remapped-mojang
+java -jar ./BuildTools.jar --rev 1.18 --remapped remapped-mojang
+java -jar ./BuildTools.jar --rev 1.18.1 --remapped remapped-mojang
+```
+Yes it's a lot, yes it will likely take a while to build all of these spigot versions. Only versions after 1.17 use remapped jars.
