ICU User Guide

The ICU User Guide provides information on i18n topics for which ICU has services, and includes details that go beyond the C, C++, and Java API docs (and avoids some duplication between them).

This is the new home of the User Guide (since 2020 August).

ICU team member pages

Other documentation pages here are written by and for team members.
