+
+## 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).
