 2. For consistent ordering **create all folders in lowercase**.
 3. Include a **README.md** file that explains the sample. A good description helps other community members to understand your sample. The README.md uses [Github Flavored Markdown](https://guides.github.com/features/mastering-markdown/) for formatting text. If you want to add images to your README.md file, store the images in the **images** folder. Reference the images in the README.md with a relative path (e.g. `![alt text](images/sampleImage.png "Sample Image Text")`). This ensures the link will reference the target repository if the source repository is forked.
