Analyze the following repository files and directory structure to generate GitHub Actions workflow steps for environment setup and dependency installation.

**Repository Files:**
{repo_files}

**Directory Structure (2 levels):**
{directory_structure}

**Codeflash Configuration (if available):**
{codeflash_config}

Based on this information, generate the `steps:` section of a GitHub Actions workflow that will:
1. Checkout the repository
2. Set up the language runtime with the appropriate version
3. Set up the dependency/package manager
4. Install dependencies
5. Install any required system packages

Return ONLY the YAML steps section, no additional text or markdown formatting.
