Add tracing to /lp verbose, API updates/cleanup, add login process event, and utilise string interning for faster context/node comparisons

- Remove usage of Java 8 streams from frequently called methods
- Use LinkedLists where appropriate to improve Iterator#remove speed
- Cache immutable multimap conversion
- Rename some methods to make the intended use/behaviour clearer

 ## Useful Links
 * **Development Builds** - <https://ci.lucko.me/job/LuckPerms>
-* **Javadocs** - <https://jd.lucko.me/LuckPerms>
+* **Javadocs** - <https://luckperms.lucko.me/javadocs/>
 * **Wiki** - <https://github.com/lucko/LuckPerms/wiki>
 
 ## Building
 LuckPerms uses Maven to handle dependencies.
 
 #### Requirements
+* Java 8 JDK
 * Maven 3.3.x (the older versions will not work.)
 * Git
 
 #### Then run
 ```sh
 git clone https://github.com/lucko/LuckPerms.git
+cd LuckPerms/
 mvn clean package
 ```
 
+You can find the output jars in the `target` directories.
+
+## Contributing
+In order to contribute to and make changes to the plugin, you will need the dependencies listed above, plus the [Lombok plugin](https://projectlombok.org/download.html) for your IDE. 
+
+#### Pull Requests
+If you make any changes or improvements to the plugin which you think would be beneficial upstream, please consider making a Pull Request to merge your changes back into the upstream project. (especially if your changes are bug fixes!)
+
+LuckPerms loosely follows the [Google Java Style Guide](https://google.github.io/styleguide/javaguide.html), with a few minor changes here and there. Generally, try to copy the style of code found in the class you're editing. 
+
+#### Project Layout
+The project is split up into 5 seperate modules.
+
+* **API** - The public facing API classes used by other plugins when integrating with LuckPerms. This is basically just a collection of interfaces implemented inside of the plugin.
+* **Common** - This includes all of the classes shared by separate implementations of LuckPerms. This is where the bulk of the project is.
+* **Bukkit, BungeeCord & Sponge** - Includes all of the platform specific classes used to implement LuckPerms on each of the 3 supported platforms.
