+# Code Generator Evaluator
+
+## Getting Started
+1. Move to the evaluator directory
+
+```bash
+cd dify/evaluate/code-generator
+```
+
+2. Set up your `.env` file with required variables
+```bash
+cp .env.example .env
+```
+
+3. Add your test cases to `testdata/testcases.json`
+
+
+4. Execute the evaluator
+
+```bash
+# For Linux
+./bin/evaluate-code-linux
+
+# For macOS (Intel)
+./bin/evaluate-code-mac
+
+# For macOS (Apple Silicon)
+./bin/evaluate-code-mac-arm64
+
+# For Windows
+./bin/evaluate-code.exe
+```
+
+
+## Build Instructions
+
+### 1. Prepare Build Script
+First, grant execution permissions to the build script:
+```bash
+chmod +x build.sh
+```
+
+### 2. Prerequisites
+- Go 1.20 or higher
+- Properly configured `GOPATH`
+
+### 3. Build Process
+Run the cross-platform build with the following command:
+```bash
+./build.sh
+```
+
+## Running the Evaluator
+Execute the Code Generator evaluation on your platform using:
+
+```bash
+# For Linux
+./bin/evaluate-code-linux
+
+# For macOS (Intel)
+./bin/evaluate-code-mac
+
+# For macOS (Apple Silicon)
+./bin/evaluate-code-mac-arm64
+
+# For Windows
+./bin/evaluate-code.exe
+```
