+# ForgeWrapper
+
+Allow MultiMC to launch Minecraft 1.13+ with Forge.
+
+## How to use
+
+1. Download Forge installer for Minecraft 1.13+ at [https://files.minecraftforge.net/].
+2. Download ForgeWrapper jar file at the [release](https://github.com/ZekerZhayard/ForgeWrapper/releases) page.
+3. Run the below command in terminal:
+  ```
+  java -jar <ForgeWrapper.jar> [--installer] <forge-installer.jar> [--instance <instance-path>]
+  ```
+  *Notice: If you don't specify a MultiMC instance path, ForgeWrapper will create the instance folder in current working space.*
+4. If the instance folder which just created is not in `MultiMC/instances` folder, you just need to move to the `MultiMC/instances` folder.
+5. Run MultiMC, and you will see a new instance named `forge-<mcVersion>-<forgeVersion>`.
