### 无限制的“插件” { #unlimited-plug-ins }

或者说，导入并使用你需要的代码，而不需要它们。

任何集成都被设计得被易于使用（用依赖关系），你可以用和*路径操作*相同的结构和语法，在两行代码中为你的应用创建一个“插件”。

## 4. Install Certificates from Third-party CAs

MinIO can connect to other servers, including MinIO nodes or other server types such as NATs and Redis. If these servers use certificates that were not registered with a known CA, add trust for these certificates to MinIO Server by placing these certificates under one of the following MinIO configuration paths:

* **Linux:** `~/.minio/certs/CAs/`
* **Windows**: `C:\Users\<Username>\.minio\certs\CAs`
