-# UE4 Plugin: kd-tree
+# Unreal Engine Plugin: kd-tree
 
 This is a UE4 plugin to provide utility functions for building kd-tree as
 Blueprint Function Library.
 
-## Supported Environment
-
-This plugin is tested on the below environment.
-
-* UE4 Version: 4.22
-* OS: Windows/Mac
-
-## Installation
-
-### 1. Download source code
-
-Download whole project's source code from
-[GitHub](https://github.com/nutti/UE4-Kdtree/archive/master.zip) and unzip it.
-
-### 2. Move the plugin
-
-Move the plugin folder (`Kdtree` directory) into the "Plugins" directory in
-your UE4 project folder.
+## Features
 
-### 3. (re-) Generate project files
+* Build kd-tree.
+* Radius search by using kd-tree.
+* Support synchronous and asynchronous versions.
 
-Generate project files (for example with RMouseButton on the \*.uproject) for
-Visual Studio (Windows) or XCode (Mac).
-
-### 4. Build
-
-Build the project.
-
-### 5. Launch UE4 editor and enable the plugin
-
-Launch .uproject file and enable the plugin via *Settings* > *Plugins* >
-*Project* > *Other* > *kd-tree*.

-## Features / Tutorials
-
-### Build kdtree and radius search
+## Supported Environment
 
-1. `Build Kdtree` builds a kd-tree (`Kdtree` object in Blueprint) from `Vector`
-   objects.
-   * `Dump Kdtree to Console` outputs the internal information of `Kdtree`
-     object to the console for debugging.
-   * `Validate Kdtree` checks the `Kdtree` object and halts the game play if
-     there is a incorrect in it.
-2. `Collect from Kdtree` collects `Vector` objects in the sphere (center
-   location is `Center`, radius is `Radius`). `Collect from Kdtree` also
-   returns indicies of list that is input argument of `Build Kdtree`.
-3. If you don't use `Kdtree` any more, you can destroy `Kdtree` object and free
-   memories by `Clear Kdtree`.
+This plugin supports on the below environment.
 
-![kdtree](docs/images/kdtree.png)
+* Unreal Engine Version: 4.22-4.27, 5.0-
+* Development Platforms: Windows, macOS, Linux
+* Target Build Platforms: All platforms
 
-### Build kdtree and radius search (Async version)
+## Installation
 
-Async version is also provided by this plugin.
+See [the installation document](docs/installation.md).
 
-1. `Build Kdtree Async` is an asynchronous version of `Build Kdtree`.
-   * All synchronous versions (`Collect from Kdtree`, `Dump Kdtree to Console`,
-     `Validate Kdtree` and `Clear Kdtree`) can be applicatable to `Kdtree`
-     object after `Build Kdtree Async` is completed.
-2. `Collect from Kdtree Async` is an asynchronous version of
-   `Collect from Kdtree`.
