 ## For Developers
-To compile, the relevant Craftbukkit/Spigot jars must be installed in your local repository using the install plugin.  
-Ex: `mvn install:install-file -Dpackaging=jar -Dfile=spigot-1.11-R0.1-SNAPSHOT.jar -DgroupId=org.spigotmc -DartifactId=spigot -Dversion=1.11-R0.1-SNAPSHOT`
 
-To compile for a specific version or set of versions, you'll need to use a profile. Provided profiles are `latest`, `modern` (versions 1.8+), and `all`. Select an existing profile using the `-P` argument (ex: `mvn clean package -am -P all`) or make your own. For more information, check out the [official guide](http://maven.apache.org/guides/introduction/introduction-to-profiles.html).
-
-The final file is target/OpenInv.jar

+To compile, the relevant Spigot jars must be installed in the local repository.
+As OpenInv is compiled against Mojang's mappings, you must run BuildTools with the `--remapped` argument:  
+`java -jar BuildTools.jar --remapped --rev $serverVersion`  
+`$serverVersion` is the version of the server, i.e. `1.18.1`
