+## Small ICU
+
+Node.js binaries built by this project use the `small-icu` option to reduce the size of the binary. If you need a Node.js binary with full ICU support, you can build it yourself by setting the `--with-intl=full-icu` option. Small ICU is sufficient for most use cases, and it reduces the binary size by about 30 MB.
