-# ProtocolLib [![Travis Status](https://travis-ci.org/dmulloy2/ProtocolLib.svg?branch=master)](https://travis-ci.org/dmulloy2/ProtocolLib)
-
-Certain tasks are impossible to perform with the standard Bukkit API, and may require 
-working with and even modify Minecraft directly. A common technique is to modify incoming 
-and outgoing [packets](http://www.wiki.vg/Protocol), or inject custom packets into the
-stream. This is quite cumbersome to do, however, and most implementations will break 
-as soon as a new version of Minecraft has been released, mostly due to obfuscation.
-
-Critically, different plugins that use this approach may _hook_ into the same classes, 
-with unpredictable outcomes. More than often this causes plugins to crash, but it may also 
-lead to more subtle bugs.
-
-Currently maintained by dmulloy2 on behalf of [Spigot](http://www.spigotmc.org/).

-### Resources
-
-* [Resource Page](http://www.spigotmc.org/resources/protocollib.1997/)
-* [Dev Builds](http://ci.dmulloy2.net/job/ProtocolLib)
-* [JavaDoc](http://ci.dmulloy2.net/job/ProtocolLib/javadoc)
-
-### Compilation
-
-ProtocolLib is built with Maven and requires Spigot and SpigotAPI, which can be found [here](http://www.spigotmc.org/wiki/buildtools/).
-
-### A new API
-
-__ProtocolLib__ attempts to solve this problem by providing a event API, much like Bukkit, 
-that allows 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. 
-You no longer have to reference CraftBukkit!
-
-### Using ProtocolLib
-
-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:
-
-````yml
-depend: [ProtocolLib]
-````
-
-You can also add ProtocolLib as a Maven dependency:
-
-````xml
-<repositories>
-  <repository>
-    <id>dmulloy2-repo</id>
-    <url>http://repo.dmulloy2.net/content/groups/public/</url>
-  </repository>
-  ...
-</repositories>
-
-<dependencies>
-  <dependency>
-    <groupId>com.comphenix.protocol</groupId>
-    <artifactId>ProtocolLib</artifactId>
-    <version>3.6.5</version>
-  </dependency>
-</dependencies>
-````
-
-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:
-
-````java
-// Disable all sound effects
-protocolManager.addPacketListener(
-  new PacketAdapter(this, ListenerPriority.NORMAL, 
-          PacketType.Play.Server.NAMED_SOUND_EFFECT) {
-    @Override
-    public void onPacketSending(PacketEvent event) {
-        // Item packets (id: 0x29)
-        if (event.getPacketType() == 
-                PacketType.Play.Server.NAMED_SOUND_EFFECT) {
-            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:
-
-````java
-// Censor
-protocolManager.addPacketListener(new PacketAdapter(this,
-        ListenerPriority.NORMAL, 
-        PacketType.Play.Client.CHAT) {
-    @Override
-    public void onPacketReceiving(PacketEvent event) {
-        if (event.getPacketType() == PacketType.Play.Client.CHAT) {
-            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:
-
-````java
-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>();
-
-((CraftPlayer) player).getHandle().netServerHandler.sendPacket(fakeExplosion);
-````
-
-But with ProtocolLib, you can turn that into something more manageable. Notice that 
-you don't have to create an ArrayList with this version:
-
-````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);
-
-try {
-    protocolManager.sendServerPacket(player, fakeExplosion);
-} catch (InvocationTargetException e) {
-    throw new RuntimeException(
-        "Cannot send packet " + fakeExplosion, e);
-}
-````
-
-### Compatibility
-
-One of the main goals of this project was to achieve maximum compatibility with CraftBukkit. And the end
-result is quite flexible. Aside from netty package changes, it should be resilient against future changes.
-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 - 
-every field, method and class is deduced by looking at field types, package names or parameter
-types. It's remarkably consistent across different versions.
-
-
