 ## Introduction

 HMCL is a Minecraft launcher which supports Mod management, game customizing, auto installing(Forge, LiteLoader and OptiFine), modpack creating, UI customizing and so on.

+## Downloads
+
+Binary version can be found here: https://ci.huangyuhui.net/job/HMCL
+
+Archives in GitHub releases are built by closed CIs, uploaded here for backup.
+
 ## Contribution
+
 If you want to submit a pull request, there're some requirements:
 * IDE: Intellij IDEA.
 * Compiler: Java 1.8.
 * Do NOT modify `gradle` files.

 ## HMCLCore
+
 Now HMCLCore is independent and you can use HMCLCore as a library to launch your game.

 ### GameRepository
+
 Create a game repository `repository` to manage a minecraft installation. Like this.
 ```java
 DefaultGameRepository repository = new DefaultGameRepository(new File(".minecraft").getAbsoluteFile());

 ### Downloading
 HMCLCore just owns a simple way to download a new game.
 ```java
-DefaultDependencyManager dependency = new DefaultDependencyManager(repository, MojangDownloadProvider.INSTANCE, proxy);
+DefaultDependencyManager dependency = new DefaultDependencyManager(repository, new MojangDownloadProvider(), proxy);
 ```
 `repository` is your `GameRepository`. `MojangDownloadProvider.INSTANCE` means that we download files from mojang servers. If you want BMCLAPI, `BMCLAPIDownloadProvider.INSTANCE` is just for you. `proxy` is `java.net.Proxy`, if you have a proxy, put it here, or `Proxy.NO_PROXY`.

 Now `GameBuilder` can build a game.
-```
+```java
 Task gameBuildingTask = dependency.gameBuilder()
                .name("test")
                .gameVersion("1.12") // Minecraft version
                .version("forge", "14.21.1.2426") // Forge version
                .version("liteloader", "1.12-SNAPSHOT-4") // LiteLoader version
                .version("optifine", "HD_U_C4") // OptiFine version
-                .buildAsync()
+                .buildAsync();
 ```

 Nowadays HMCLCore only supports Forge, LiteLoader and OptiFine auto-installing.
 `buildAsync` will return a `Task`, you can call `Task.executor()::start` or simply `Task::start` to start this task. If you want to monitor the execution of tasks, you should see `TaskExecutor` and `Task::executor`.

+### Modpack installing
+
+HMCLCore supports Curse, MultiMC modpack.
+
+```java
+// Installing curse modpack
+new CurseInstallTask(dependency, modpackZipFile, CurseManifest.readCurseForgeModpackManifest(modpackZipFile), "name of the new game");
+
+// Installing MultiMC modpack
+new MultiMCModpackInstallTask(dependency, modpackZipFile, MultiMCInstanceConfiguration.readMultiMCModpackManifest(modpackZipFile), "name of the new game");
+// ** IMPORTANT **: You should read game settings from MultiMCInstanceConfiguration
+```
+
 ## HMCL
-JavaFX version of HMCL does not support old APIs.
+
+No plugin API.
