<recommendations>
<recommendation>Start with understanding basic OS concepts before diving into implementation</recommendation>
<recommendation>Focus on one platform initially (e.g., Linux) before expanding to others</recommendation>
<recommendation>Study the platform-specific APIs and documentation thoroughly</recommendation>
<recommendation>Practice with FFI and unsafe Rust in isolated examples first</recommendation>
<recommendation>Use the sandboxed test environment for development</recommendation>
<recommendation>Begin with small contributions to platform-specific modules</recommendation>
