Document code thoroughly

Always include appropriate documentation in your code to improve readability, maintainability, and usability:

1. Document all public APIs with Go doc comments:

   // MetricsExporter provides functionality for exporting metrics to Prometheus
   // and managing metrics collection within the application.
   type MetricsExporter struct {
       // fields...
   }
      
   // IncRequestCounter increments the request counter for the specified kind.
   // It tracks API usage patterns for monitoring purposes.
   func IncRequestCounter(kind string) {
       // implementation...
   }
   

2. Explain complex logic with inline comments, especially when there are relationships between components or non-obvious behaviors:

   // Update the CR status based on the ContainerState of the container
   // that has the same name as the CR
   if len(pod.Status.ContainerStatuses) > 0 {
       // implementation...
   }
   

3. Document code modifications by adding TODOs with context for commented-out or temporary code:

   // TODO(user): This endpoint is temporarily disabled until issue #123 is resolved
   // which addresses the race condition in the deployment creation process.
   //
   //// GetLatestKfdef returns latest kfdef status.
   

Following these practices ensures code is understandable to new team members, facilitates easier maintenance, and helps API consumers use your code correctly. Run tools like go vet ./... regularly to catch missing documentation on public elements.
