+Contributing to ProtocolLib
+===========================
+This page will detail specific things that must be done if you intend to contribute to this project.
+
+## Updating ProtocolLib to a New Protocol Version
+#### Before we get started:
+1. **When do we need to update the protocol version?**
+    _A Minecraft protocol version is a number for each specification of the Minecraft protocol.
+    This means it is incremented when there is a change to the [Protocol Specification](http://wiki.vg/Protocol),
+    but not necessarily for each Minecraft version update. If the latest Minecraft version contains a protocol change,
+    that means ProtocolLib needs to be updated._
+2. **When do we need to update other parts of ProtocolLib?**
+    _When the package version guard changes. The package version guard is the version string inserted
+    into the package identifier for CraftBukkit and net.minecraft.server (e.g. v1_9_R2). It is incremented
+    by Spigot if there is a major breaking change in the internal server code. This is to encourage plugins
+    that interact directly with CraftBukkit/nms code to update more specifically. However, since most of
+    ProtocolLib uses reflection, and the structure of packet classes is generally static, one will have
+    to go through the code and change imports from nms/CraftBukkit._
+
+#### Ready? Let's get started!
+1. Read the [Protocol Changes](http://wiki.vg/Protocol_History). Always make sure the list is both
+complete and correct. If you're unsure, don't hesitate to ask in #mcdevs (the people who maintain wiki.vg) on [libera.chat](http://libera.chat)
+or #spigot on [irc.spi.gt](http://irc.spi.gt) ([webchat](https://irc.spi.gt/iris/?channels=spigot)).
+2. Search for usages of the now-defunct NMS package guard and change them.
+3. The class `com.comphenix.protocol.PacketType` contains a list of all the packets. If any packets were added or removed
+(or had their ID changed), make sure to update this list. If a packet was removed
+in favor of usage of another packet, instead of removing it, move it to the bottom of the list
+in its section, add a deprecation warning to it, and redirect it to the packet that replaced it.
+4. `mvn` in the root directory to build the project.
+5. If tests fail in the maven build, go through the tests to make sure you removed references to any removed packets
+and changed the NMS version guards.
+6. Increment the package version in `com.comphenix.protocol.utility.Constants`.
+7. `com.comphenix.protocol.ProtocolLibrary` contains several constants that must be updated, including the Minecraft version
+and the release date.
+8. `com.comphenix.protocol.utility.MinecraftProtocolVersion` contains a map of all the protocol version integers.
+If the protocol version has been incremented, add a new line to the map.
+9. `mvn` in root directory again. If it builds successfully, test on the appropriate version of a Spigot server. If
+the build fails, debug!

---------
-You can compile this project yourself by using the latest version of Maven.
+ProtocolLib is built with [Maven](https://maven.apache.org/). If you have it installed, just run
+`mvn package` in the root project folder.
 
+### A new API
 
-A new API
----------
-
-__ProtocolLib__ attempts to solve this problem by providing a event API, much like Bukkit, 
-that allow plugins to monitor, modify or cancel packets sent and received. But more importantly, 
-the API also hides all the gritty, obfuscated classes with a simple index based read/write system.

+the API also hides all the gritty, obfuscated classes with a simple index based read/write system.
 You no longer have to reference CraftBukkit!

 ### Using ProtocolLib
 
-To use the library, first add ProtocolLib.jar to your Java build path. Then, add ProtocolLib
-as a dependency (or soft-dependency, if you can live without it) to your plugin.yml file:
+To use this library, first add ProtocolLib.jar to your Java build path. Then, add ProtocolLib
+as a dependency or soft dependency to your plugin.yml file like any other plugin:
 
-    depends: [ProtocolLib]
+````yml
+depend: [ ProtocolLib ]
+````
 
-Future versions will be available in a public Maven repository, possibly on Maven central. But it
-will always be possible to reference ProtocolLib manually.
+You can also add ProtocolLib as a Maven dependency:
 
-Then get a reference to ProtocolManager in onLoad() and you're good to go.
+````xml
+<repositories>
+  <repository>
+    <id>dmulloy2-repo</id>
+    <url>https://repo.dmulloy2.net/repository/public/</url>
+  </repository>
+</repositories>
 
-    private ProtocolManager protocolManager;
-    
-    public void onLoad() {
-        protocolManager = ProtocolLibrary.getProtocolManager();
-    }
+<dependencies>
+  <dependency>
+    <groupId>com.comphenix.protocol</groupId>
+    <artifactId>ProtocolLib</artifactId>
+    <version>4.7.0</version>
+    <scope>provided</scope>
+  </dependency>
+</dependencies>
+````
+
+Or use the maven dependency with gradle:
+
+```gradle
+repositories {
+    maven { url "https://repo.dmulloy2.net/repository/public/" }
+}
+
+dependencies {
+    compileOnly group: "com.comphenix.protocol", name: "ProtocolLib", version: "4.7.0";
+}
+```
+
+Then get a reference to ProtocolManager in onLoad() or onEnable() and you're good to go.
+
+````java
+private ProtocolManager protocolManager;
+
+public void onLoad() {
+    protocolManager = ProtocolLibrary.getProtocolManager();
+}
+````
 
 To listen for packets sent by the server to a client, add a server-side listener:
 
-    // Disable all sound effects
-    protocolManager.addPacketListener(
-      new PacketAdapter(this, ConnectionSide.SERVER_SIDE, ListenerPriority.NORMAL, 0x3E) {
-        @Override
-        public void onPacketSending(PacketEvent event) {
-            // Item packets
-            switch (event.getPacketID()) {
-            case 0x3E: // Sound effect
-                event.setCancelled(true);
-                break;
-            }
-        }
-    });
-
+````java
+// Disable all sound effects
+protocolManager.addPacketListener(new PacketAdapter(
+    this,
+    ListenerPriority.NORMAL,
+    PacketType.Play.Server.NAMED_SOUND_EFFECT
+) {
+    @Override
+    public void onPacketSending(PacketEvent event) {
+        event.setCancelled(true);
+    }
+});
+````
 
 It's also possible to read and modify the content of these packets. For instance, you can create a global
 censor by listening for Packet3Chat events:
 
-    // Censor
-    protocolManager.addPacketListener(
-      new PacketAdapter(this, ConnectionSide.CLIENT_SIDE, ListenerPriority.NORMAL, 0x03) {
-        @Override
-        public void onPacketReceiving(PacketEvent event) {
-            if (event.getPacketID() == 0x03) {
-                try {
-                    PacketContainer packet = event.getPacket();
-                    String message = packet.getSpecificModifier(String.class).read(0);
-                    
-                    if (message.contains("shit") || message.contains("damn")) {
-                        event.setCancelled(true);
-                        event.getPlayer().sendMessage("Bad manners!");
-                    }
-                    		
-                } catch (FieldAccessException e) {
-                    getLogger().log(Level.SEVERE, "Couldn't access field.", e);
-                }
-            }
-        }
-    });
+````java
+// Censor
+protocolManager.addPacketListener(new PacketAdapter(
+    this,
+    ListenerPriority.NORMAL,
+    PacketType.Play.Client.CHAT
+) {
+    @Override
+    public void onPacketReceiving(PacketEvent event) {
+        PacketContainer packet = event.getPacket();
+        String message = packet.getStrings().read(0);
 
+        if (message.contains("shit") || message.contains("damn")) {
+            event.setCancelled(true);
+            event.getPlayer().sendMessage("Bad manners!");
+        }
+    }
+});
+````
 
 ### Sending packets
 
 Normally, you might have to do something ugly like the following:
 
-    Packet60Explosion fakeExplosion = new Packet60Explosion();
-    	
-    fakeExplosion.a = player.getLocation().getX();
-    fakeExplosion.b = player.getLocation().getY();
-    fakeExplosion.c = player.getLocation().getZ();
-    fakeExplosion.d = 3.0F;
-    fakeExplosion.e = new ArrayList<Object>();
+````java
+PacketPlayOutExplosion fakeExplosion = new PacketPlayOutExplosion(
+    player.getLocation().getX(),
+    player.getLocation().getY(),
+    player.getLocation().getZ(),
+    3.0F,
+    new ArrayList<>(),
+    new Vec3D(
+        player.getVelocity().getX() + 1,
+        player.getVelocity().getY() + 1,
+        player.getVelocity().getZ() + 1
+    )
+);
 
-    ((CraftPlayer) player).getHandle().netServerHandler.sendPacket(fakeExplosion);
+((CraftPlayer) player).getHandle().b.a(fakeExplosion);
+````
 
-But with ProtocolLib, you can turn that into something more manageable. Notice that 
-you don't have to create an ArrayList this version:
+But with ProtocolLib, you can turn that into something more manageable:
 
-    PacketContainer fakeExplosion = protocolManager.createPacket(60);
-    
-    fakeExplosion.getSpecificModifier(double.class).
-        write(0, player.getLocation().getX()).
-        write(1, player.getLocation().getY()).
-        write(2, player.getLocation().getZ());
-    fakeExplosion.getSpecificModifier(float.class).
-        write(0, 3.0F);
-    
-    protocolManager.sendServerPacket(player, fakeExplosion);
+````java
+PacketContainer fakeExplosion = new PacketContainer(PacketType.Play.Server.EXPLOSION);
+fakeExplosion.getDoubles()
+    .write(0, player.getLocation().getX())
+    .write(1, player.getLocation().getY())
+    .write(2, player.getLocation().getZ());
+fakeExplosion.getFloat().write(0, 3.0F);
+fakeExplosion.getBlockPositionCollectionModifier().write(0, new ArrayList<>());
+fakeExplosion.getVectors().write(0, player.getVelocity().add(new Vector(1, 1, 1)));
 
+protocolManager.sendServerPacket(player, fakeExplosion);
+````
 
-Compatiblity
-------------
+### Compatibility
 
 One of the main goals of this project was to achieve maximum compatibility with CraftBukkit. And the end
-result is quite flexible - in tests I successfully ran an unmodified ProtocolLib on CraftBukkit 1.8.0, and
-it should be resiliant against future changes. It's likely that I won't have to update ProtocolLib for
-anything but bug and performance fixes. 
+result is quite flexible. It's likely that I won't have to update ProtocolLib for anything but bug fixes
+and new features.
 
-How is this possible? It all comes down to reflection in the end. Essentially, no name is hard coded - 
+How is this possible? It all comes down to reflection in the end. Essentially, no name is hard coded -
 every field, method and class is deduced by looking at field types, package names or parameter
 types. It's remarkably consistent across different versions.
