| |
| ## ICU User Guide |
| |
| The [ICU User Guide](./userguide) 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 Site |
| |
| The official ICU Site is located at https://icu.unicode.org/. |
| It is the official landing page for the ICU project. |
| |
| Some of the pages from the ICU Site have been migrated here. |
| The migrated sections and pages from the ICU Site are visible in the navigation bar of this site below the "ICU Site" section heading. |
| |
| ## Downloading ICU |
| |
| The [Downloading ICU](download) page has been migrated here. |
