# Development Considerations

The same development rules that apply for any programming environment apply to ColdFusion. You should also follow the same programming conventions that you would with any other language:

- Comment your code as you go.

  HTML comments use this syntax: `<!-- html comment -->`

  CFML comments add an extra dash: `<!--- cfml comment --->`

- File names should be all one word, begin with a letter and can contain only letters, numbers and the underscore.
- File names should not contain special characters.
