+## Most artifacts are now built in the GitHub CI. Work in Progress!!!
+
+Many of the tasks that used to be done before "by hand" are now at least
+partially done by GitHub Actions.
+
+The release requires (for now) triggering the actions "by hand".
+
+First go to [Github - unicode-org/icu](https://github.com/unicode-org/icu).
+
+Create a release, give it a tag (something like `release-76` or `release-74-2`) \
+Make sure the release is **DRAFT**.
+
+See [Release & Milestone Tasks - Tagging](index.md#tagging) for details.
+
+That tag will need to be passed to several of the actions below.
+
+Go to [Github - unicode-org/icu](https://github.com/unicode-org/icu) -- Actions
+and select the action to run from the left side.
+
+Select an action and (from the right side) select "Run workflow".
+
+Some actions will have an "Run the tests." option. \
+**KEEP IT ON!** It is there for development, but you MUST run the tests for release.
+
+Most will have a "Release tag to upload to." option. \
+Here you should use the release tag.
+
+1. **GHA ICU4C** \
+   This will create and add to release: \
+   * The Windows binaries (`icu4c-{icuver}-Win32-MSVC20??.zip`,
+   `icu4c-{icuver}-Win64-MSVC20??.zip`, `icu4c-{icuver}-WinARM64-MSVC20??.zip`)
+   * The packaged data for ICU4X (`icuexportdata_tag-goes-here.zip`)
+
+1. **Release - ICU4C artifacts on Fedora** (`release-icu4c-fedora.yml`) \
+   This will create and add to release:
+   * `icu4c-{icuver}-Fedora_Linux??-x64.tgz`.
+
+1. **Release - ICU4C artifacts on Ubuntu** (`release-icu4c-ubuntu.yml`) \
+   This will create and add to release:
+   * The `icu4c-{icuver}-Ubuntu??.04-x64.tgz` file
+   * The icu4c data files (`icu4c-{icuver}-data.zip`,
+     `icu4c-{icuver}-data-bin-b.zip`, `icu4c-{icuver}-data-bin-l.zip`)
+   * The icu4c source archives (`icu4c-{icuver}-src.tgz` and `icu4c-{icuver}-src.zip`)
+   * The ICU4C documentation (`icu4c-76_1-docs.zip`) \
+   **WARNING:** this is also the one to be published (unpacked) for web access
+
+1. **Release - ICU4J publish to Maven Central** (`release-icu4j-maven.yml`) \
+   This will create, publish to Maven Cental (using Sonatype), and add to release:
+   * All the official Maven artifacts, including sources and javadoc. \
+     The Maven Central artifacts have checksums and are digitally signed. \
+     Someone with access to Sonatype Nexus should still login there and authorize
+     the promotion to Maven Central.
+   * The unified Java documentation, (`icu4j-76.1-fulljavadoc.jar`) \
+     **WARNING:** this is also the one to be published (unpacked) for web access
+
+1. **Release - Create checksums and GPG sign** (`release-check-sign.yml`) \
+   THIS SHOULD BE THE LAST ACTION YOU RUN. \
+   After all the artifacts from the previous steps are posted to the release. \
+   The action will download all the artifacts from release,
+   create checksum files (`SHASUM512.txt` and `*.md5`),
+   and digital signature files (`*.asc`)
