 ## Advanced usage
 
+### Custom Inno Setup path
+
+By default, `fastforge` looks for Inno Setup 6 at `C:\Program Files (x86)\Inno Setup 6`. If you have installed Inno Setup in a different location, you can specify the custom path using the `inno_setup_path` option in your `make_config.yaml`:
+
+```yaml
+# Custom Inno Setup installation path
+inno_setup_path: "D:\Tools\Inno Setup 6"
+```
+
 ### Custom Inno Setup template
 
 By default, `fastforge` will generate an Inno Setup configuration (`.iss`) based on an internal template on build time, and populate it with the values provided in `make_config.yaml`. If you need more control over the Inno Setup configuration, you can provide a custom template using the `script_template` option.

 ## 高级用法
 
+### 自定义 Inno Setup 路径
+
+默认情况下，`fastforge` 在 `C:\Program Files (x86)\Inno Setup 6` 路径查找 Inno Setup 6。如果你将 Inno Setup 安装在其他位置，可以在 `make_config.yaml` 中使用 `inno_setup_path` 选项指定自定义路径：
+
+```yaml
+# 自定义 Inno Setup 安装路径
+inno_setup_path: "D:\Tools\Inno Setup 6"
+```
+
 ### 自定义 Inno Setup 模板
 
 默认情况下，`fastforge` 会在构建时基于内部模板生成一个 Inno Setup 配置（`.iss`），并将其填充到 `make_config.yaml` 中提供的值。如果你需要对 Inno Setup 配置进行更多控制，你可以使用 `script_template` 选项提供一个自定义模板。

+# Example: Using Custom Inno Setup Path
+
+This example demonstrates how to configure fastforge to use a custom Inno Setup installation path.
+
+## Configuration
+
+Add the following to your `windows/packaging/exe/make_config.yaml`:
+
+```yaml
+# Basic app information
+app_id: 5B599538-42B1-4826-A479-AF079F21A65D
+publisher: LeanFlutter
+publisher_url: https://github.com/fastforgedev/fastforge
+display_name: Hello 世界
+create_desktop_icon: true
+
+# Custom Inno Setup path
+inno_setup_path: "D:\Tools\Inno Setup 6"
+
+locales:
+  - en
+  - zh
+```
+
+## Use Cases
+
+This feature is useful when:
+
+1. **Non-standard Installation**: You installed Inno Setup in a custom directory
+2. **Portable Installation**: You're using a portable version of Inno Setup
+3. **Multiple Versions**: You have multiple versions of Inno Setup and want to use a specific one
+4. **CI/CD Environments**: You have Inno Setup installed in a specific location in your build agents
+
+## Fallback Behavior
+
+If `inno_setup_path` is not specified or is `null`, fastforge will use the default path:
+`C:\Program Files (x86)\Inno Setup 6`
+
+This ensures backward compatibility with existing configurations.
