+= Fawe annotations explained
+
+If we have modified parts of the WorldEdit codebase, we considered annotating it with different styles of comments, which
+are explained in this document.
+
+== In-line annotations
+
+[source,java]
+-----------------
+public static Player adapt(com.sk89q.worldedit.entity.Player player) {
+        //FAWE start - Get player from PlayerProxy instead of BukkitPlayer if null
+        player = PlayerProxy.unwrap(player);
+        return player == null ? null : ((BukkitPlayer) player).getPlayer();
+        //FAWE end
+}
+-----------------
+The `-sources` jar retains comments, if you add the FAWE API to your maven or gradle project, you can view differences between the projects with ease.
+Behind the `//FAWE start - ` you can find a comment what has been changed and why it has been changed.
+
+== Block annotations
+
+[source,java]
+-----------------
+//FAWE start
+    @Override
+    public void setPermission(String permission, boolean value) {
+    }
+//FAWE end
+-----------------
+Annotations can cover whole methods or go beyond the method and wrap around several added methods.
+
+== Package annotations
+Class additions are added under the `com.fastasyncworldedit` namespace, but sometimes classes need to be added in package private.
+If that is done, you can find a `package-info.java` file within the package affected that outlines FAWE added classes:
+[source,java]
+-----------------
+/**
+* The following classes are FAWE additions:
+*
+* @see com.sk89q.worldedit.world.block.BlockTypesCache
+*/
+package com.sk89q.worldedit.world.block;
+-----------------
+
+== Undocumented annotations
+Specific changes are not annotated:
+
+* `com.fastasyncworldedit.core.configuration.Caption` in `com.sk89q.worldedit` packages have been changed from
+`com.sk89q.worldedit.util.formatting.text.Text` to allow the usage of color codes for messages.
+
+* Certain Log4J loggers have been adjusted to use the proper format of placeholders.

+= Compiling
+
+You can compile FastAsyncWorldEdit as long as you have some version of Java greater than or equal to 17 installed. Gradle will download JDK 17 specifically if needed,
+but it needs some version of Java to bootstrap from.
+
+Note that if you have JRE 8 installed, Gradle will currently attempt to use that to compile, which will not work. It is easiest to uninstall JRE 8 and replace it with JDK 17.
+
+You can get the JDK 17 link:https://adoptium.net/[here] from Adoptium.
+
+The build process uses Gradle, which you do *not* need to download. FastAsyncWorldEdit is a multi-module project with three active modules:
+
+* `worldedit-core` contains the FastAsyncWorldEdit API
+* `worldedit-bukkit` is the Bukkit plugin
+* `worldedit-cli` is the command line interface
+
+== To compile...
+
+=== On Windows
+
+1. Shift + right-click the folder with FastAsyncWorldEdit's files and click "Open command prompt".
+2. `gradlew clean build`
+
+=== On Linux, BSD, or Mac OS X
+
+1. In your terminal, navigate to the folder with FastAsyncWorldEdit's files (`cd /folder/of/fawe/files`)
+2. `./gradlew clean build`
+
+== Then you will find...
+
+You will find:
+
+* The core FastAsyncWorldEdit API in **worldedit-core/build/libs**
+* FastAsyncWorldEdit for Bukkit in **worldedit-bukkit/build/libs**
+* the CLI version in **worldedit-cli/build/libs**
+
+If you want to use FastAsyncWorldEdit, use the `FastAsyncWorldEdit-<identifier>` version obtained in **worldedit-bukkit/build/libs**.
+
+(The `-#` version includes FastAsyncWorldEdit + necessary libraries.)
+
+== Other commands

+* `gradlew idea` will generate an link:https://www.jetbrains.com/idea/[IntelliJ IDEA] module for each folder.
+

-You can compile FastAsyncWorldEdit as long as you have the [Java Development Kit (JDK)](http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html) for Java 8.
-Newer versions of the JDK may not compile. 
-You only need one version of the JDK installed.

-Contributing
-============
-
-Thank you for your interest in contributing to FastAsyncWorldEdit! We appreciate your 
-effort, but to make sure that the inclusion of your patch is a smooth process, we
-ask that you make note of the following guidelines.
-
-* **Follow the [Oracle coding conventions](http://www.oracle.com/technetwork/java/codeconv-138413.html).**
-  We can't stress this enough; if your code has notable issues, it may delay
-  the process significantly.
-* **Target Java 8 for source and compilation.** Make sure to mark methods with
-  ` @Override` that override methods of parent classes, or that implement
-  methods of interfaces.
-* **Use only spaces for indentation.** Our indents are 4-spaces long, and tabs
-  are unacceptable.
-* **Wrap code to a 120 column limit.** We do this to make side by side diffs
-  and other such tasks easier. Ignore this guideline if it makes the code
-  too unreadable.
-* **Write complete Javadocs.** Do so only for public methods, and make sure
-  that your `@param` and `@return` fields are not just blank.
-* **Don't tag classes with @author.** Some legacy classes may have this tag,
-  but we are phasing it out.
-* **Make sure the code is efficient.** One way you can achieve this is to spend
-  around ten minutes to think about what the code is doing and whether it
-  seems awfully roundabout. If you had to copy the same large piece of
-  code in several places, that's bad.
-* **Keep commit summaries under 70 characters.** For more details, place two
-  new lines after the summary line and write away!
-* **Test your code.** We're not interested in broken code, for the obvious reasons.
-* **Write unit tests.** While this is strictly optional, we recommend it for
-  complicated algorithms.
-
-
-Checklist
----------
-
-Ready to submit? Perform the checklist below:
-
-1. Have all tabs been replaced into four spaces? Are indentations 4-space wide?
-2. Have I written proper Javadocs for my public methods? Are the @param and
-   @return fields actually filled out?
-3. Have I `git rebase`d my pull request to the latest commit of the target
-   branch?
-4. Have I combined my commits into a reasonably small number (if not one)
-   commit using `git rebase`?
-5. Have I made my pull request too large? Pull requests should introduce
-   small sets of changes at a time. Major changes should be discussed with
-   the team prior to starting work.
-6. Are my commit messages descriptive?
-
-You should be aware of [`git rebase`](http://learn.github.com/p/rebasing.html).
-It allows you to modify existing commit messages, and combine, break apart, or
-adjust past changes.
-
-Example
--------
-
-This is **GOOD:**
-
-    if (var.func(param1, param2)) {
-        // do things
-    }
-
-This is **EXTREMELY BAD:**
-
-    if(var.func( param1, param2 ))
-    {
-        // do things
-    }

-
-## Building
-FAWE uses gradle to build  
-You can safely ignore `gradlew setupDecompWorkspace` if you are not planning to work on the forge side of FAWE.
-
-```
-$ gradlew setupDecompWorkspace
-$ gradlew build
-```
-
-The jar is located in `worldedit-bukkit/build/libs/FastAsyncWorldEdit-1.16-###.jar`

+
+## What is FAWE and why should I use it?
+
+FAWE is designed for efficient world editing.
+* Simple to set up and use
+* Extremely configurable
+* Uses minimal CPU/Memory
+* Safe for many players to use
+* Insanely fast, when using the slowest mode
+
+FastAsyncWorldEdit is a fork of WorldEdit that has huge speed and memory improvements and considerably more features.  
+If you use other plugins which depend on WorldEdit, simply having FAWE installed will boost their performance.
+
+## Downloads
+
+Downloads are available either on SpigotMC, Modrinth or on CurseForge.
+- [SpigotMC](https://www.spigotmc.org/resources/13932/)
+- [Modrinth](https://modrinth.com/plugin/fastasyncworldedit/)
+- [CurseForge](https://dev.bukkit.org/projects/fawe)
+
+Snapshots are available on [Jenkins](https://ci.athion.net/job/FastAsyncWorldEdit/).
+
+## Features
+
+* Over 200 Commands
+* Style and translate messages and commands
+* (No setup required) Clipboard web integration (Clipboard)
+* Unlimited //undo, per world history, instant lookups/rollback and cross server clipboards
+* Advanced per player limits (entity, tiles, memory, changes, iterations, regions, inventory)
+* Visualization, targeting modes/masks and scroll actions
+* Adds lots of powerful new //brushes and //tools.
+* Adds a lot more mask functionality. (new mask syntax, patterns, expressions, source masks)
+* Adds a lot more pattern functionality. (a lot of new pattern syntax and patterns)
+* Adds edit transforms (apply transforms to a source, e.g. on //paste)
+* Adds support for new formats (e.g. Structure Blocks)
+* Instant copying of arbitrary size with `//lazycopy`
+* Auto repair partially corrupt schematic files
+* Biome mixing, in-game world painting, dynamic view distance, vanilla cui, off axis rotation, image importing, cave generation,
+  multi-clipboards, interactive messages, schematic visualization, lag prevention, persistent brushes + A LOT MORE
+
+### Performance
+
+There are several placement modes, each supporting higher throughput than the previous. All editing is processed
+asynchronously, with
+certain tasks being broken up on the main thread. The default mode is chunk placement.
+* Blocks (Bukkit-API) - Only used if chunk placement isn't supported. Still faster than any other plugin on spigot.
+* Chunks (NMS) - Places entire chunk sections
+* World (CFI) - Used to generate new worlds / regions
+
+### Protection Plugins
+
+The following plugins are supported with Bukkit:
+* [WorldGuard](https://dev.bukkit.org/projects/worldguard)
+* [PlotSquared](https://www.spigotmc.org/resources/77506/)
+
+### Logging and Rollback
+
+By default you can use `//inspect` and `//history rollback` to search and restore changes. To reduce disk usage, increase the
+compression level and buffer size. To bypass logging use `//fast`.
+
+### Developer API
+
+FAWE maintains API compatibility with WorldEdit, so you can use the normal WorldEdit API asynchronously.
+FAWE also has some asynchronously wrappers for the Bukkit API.
+The wiki has examples for various things like reading NBT, modifying world files, pasting schematics, splitting up tasks, lighting etc.
+If you need help with anything, hop on discord (link on the left bar).

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
