+### Optional Dependencies
+* [FastAsyncWorldEdit](https://www.spigotmc.org/resources/fastasyncworldedit.13932/) 2.4.5 or newer (Note: Use either FAWE or WE, not both together) 
+  * AreaShop has a separate adapter for FAWE which leverages its support for asynchronous edit operations. This adapter is used for region saving and restoring. 
+  * Note that schematics created by the FAWE adapter are not compatible with normal WorldEdit; however, schematics created by the normal WorldEdit adapter are compatible with FAWE
+  * Due to a bug with FAWE, entities are not saved by the FAWE adapter but are saved in the normal WE adapter
 
 AreaShop allows you selling and renting regions to players. It could be used to let them rent a jail in your prison server, a shop in the market of the survival server or a plot on a creative server. The player interacts with signs, making it easy to use. It also has a lot of commands to check the status of all regions, manage the renting and buying of a region and also features for admins. A lot of messages send to the player can be clicked, for immediately performing actions (buying the region, selling the region, etc.) or getting more information (for example clicking region name for region information). To setup the renting and selling of the regions exactly as you want AreaShop has a lot of options to custimize it to your liking.

-* Java 7 or higher (latest recommended)
-* Bukkit/Spigot 1.7.9 or higher (modded servers often include Bukkit/Spigot support, so it should also work on that, but it is not specifically tested for it)
-* [WorldGuard](http://dev.bukkit.org/bukkit-plugins/worldguard/): 5.9 or higher (6.0+ recommended)

-### Metrics
-This plugin utilizes Hidendra's plugin metrics system, which means that the following information is collected and sent to mcstats.org:
-
-*A unique identifier, the server's version of Java, whether the server is in offline or online mode, the plugin's version, the server's version, the OS version/name and architecture, the core count for the CPU, the number of players online, the Metrics version.*
-
-This information will give me an indication how much the plugin is used and encourages me to continue development. Opting out of this service can be done by setting `sendStats` in the config of this plugin to `false`, if you want to disable Metrics for any plugin go to `plugins/Plugin Metrics/config.yml` and change `opt-out` to `true`. Check graphs of the statistics at this page: [mcstats.org/plugin/AreaShop](http://mcstats.org/plugin/AreaShop)
-
-### Do you want to translate AreaShop?
-Help translating the plugin into different languages and to keep the translations up to date. Go to [this page](https://github.com/NLthijs48/AreaShop/wiki/Language-support#translating-on-transifex) for more information. Translating goes through the [Transifex](https://www.transifex.com/projects/p/areashop/) website and is very easy, sending files back and forth is not needed, you can translate lines online and whenever you want. Every line you translate will be saved, no need to do it all at once (this also allows for easy collaboration).

+# Compiling
+
+## Clone the repo <br/>
+`git clone https://github.com/md5sha256/AreaShop.git`
+
+## Compile a Jar
+This task may take a while as the dev environment for platform adapters in `adapters/platform` take a while to set up 
+<br/>
+<strong>Compilation command:</strong> `./gradlew build` (UNIX) or `gradlew build` (Windows)
+<br/>
+The plugin jar can be found under the `AreaShop` module in `AreaShop/build/libs/`<br/>
+There are three jars, use the one which has no suffix. Ex: `AreaShop-VERSION.jar`
+
+## Gradle Tasks
+The following is a simple table describing commands which may be useful for building the plugin. <br>
+For more details about gradle please view their documentation [here](https://docs.gradle.org/current/userguide/userguide.html).

+A shorthand for the CLI [here](https://docs.gradle.org/current/userguide/command_line_interface.html).

+| `gradlew publishToMavenLocal` | Compiles and publishes all modules except the platform adapters to `.m2`                           |
+| `gradlew clean`               | Cleans the development workspace and clears caches. Note, you don't have to clean before you build |
