Some of the key pages for developers are:

1. New CLDR Developers
   
2. Eclipse Setup
3. Eclipse (survey tool)
4. Handling Tickets (bugs/enhancements)
5. Updating DTDs
   
6. Editing CLDR Spec
7. CLDR: Big Red Switch (checklist for release)
8. Adding a new locale to CLDR

The subpages listed give more information on internal CLDR development. See also: Sitemap.

Note: when editing Sites pages it is often useful to clean up HTML in material pasted in from other sources, such as Word or Google Docs. Some useful regexes for that:

<(font|span|div)[^>]+>         <$1>

style="[^"]*"
