The Noble Eightfold Path is one of the foundations of Buddhism. The path includes:

1. Right View
2. Right Intention
3. Right Speech
4. Right Action
5. Right Livelihood
6. Right Effort
7. Right Mindfulness
8. Right Concentration

There are a variety of online resources that might help your exploration of these items. Doing a Google seach for "Buddhism Noble Eightfold Path" returns  many references. Here are a few that seem worthwhile to me:
