 ## 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`, `recent` (last 2 major Minecraft versions), 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

+      <artifactId>openinvapi</artifactId>
+      <version>${openinv.version}</version>
+    </dependency>
+  </dependencies>
 ```
+
+### Compilation
+To compile, the relevant Spigot jars must be installed in your local repository using the `install` plugin:
+```shell
+mvn install:install-file -Dpackaging=jar -Dfile=spigot-1.8-R0.1-SNAPSHOT.jar \
+    -DgroupId=org.spigotmc -DartifactId=spigot -Dversion=1.8-R0.1-SNAPSHOT
+```
+Note that BuildTools automatically installs produced files. If you use BuildTools to compile Spigot locally, you don't need to install it manually.  
+If you want to use Paper as a dependency, you can install it by executing PaperClip with the property `paperclip.install` set to true:
+```shell
+wget -O paperclip.jar https://papermc.io/api/v1/paper/1.16.5/latest/download
+java -jar -Dpaperclip.install=true paperclip.jar
+```
+
+To compile for a single version, specify the NMS revision you are targeting: `mvn -pl <NMS module> -am clean install`
+
+To compile for a set of versions, you'll need to use a profile. The only provided profile is `all`. Select a profile using the `-P` argument: `mvn clean package -am -P all`
+
+For more information, check out the [official Maven guide](http://maven.apache.org/guides/introduction/introduction-to-profiles.html).
+
+The final file is `target/OpenInv.jar`
