 Your Python code goes through several stages:
 
-1. **AST Parsing** - Python code is parsed into an Abstract Syntax Tree
-2. **IR Generation** - The AST is transformed into LLVM IR using llvmlite
-3. **BPF Compilation** - LLVM IR is compiled to BPF bytecode using `llc`
-4. **Loading** - The BPF object is loaded into the kernel using libbpf
-5. **Attachment** - Programs are attached to kernel hooks (tracepoints, kprobes, etc.)

 ## Code Organization
 
 When writing BPF programs with PythonBPF, we recommend:
 
-1. **Keep BPF code in separate files** - Easier to manage and test
-2. **Use type hints** - Required for proper code generation
-3. **Follow naming conventions** - Use descriptive names for maps and functions
-4. **Document your code** - Add comments explaining BPF-specific logic
-5. **Test incrementally** - Verify each component works before adding complexity
