| 2 So you want to add more samples: | |
| 3 1 - Create a new pre element below containing the code you want to show. | |
| 4 2 - Give it a unique id of the form "sample-name" | |
| 5 3 - In the main page, add a new option to the select element and make sure value
matches | |
| 6 the name from step #2. | |
| 7 | |
| 8 TODO: These samples are just place holders and should be replaced with something
real. | |
