+`ckormanyos/gcc-v850-unknown-elf` provides shell and YAML scripts to build a modern `gcc-v850-unknown-elf`.
 
 Design goals:
-  - Use shell and YAML scripts to build `gcc-v850-unknown-elf` from up-to-date [gcc-release(s)](https://gcc.gnu.org/pub/gcc/releases).
+  - Use shell and YAML scripts to build modern `gcc-v850-unknown-elf` on-the-fly.
+  - Build `gcc-v850-unknown-elf` from up-to-date [gcc-releases](https://ftp.gnu.org/gnu/gcc).
   - Provide a non-trivial test of the newly-built toolchain(s) based on a real-world project.
-  - Publish the build artifacts directly from the Workflow-Run(s) on GHA.
-  - Support cyclic monthly build of modern, evolving [gcc-release(s)](https://gcc.gnu.org/pub/gcc/releases).
+  - Publish the build artifacts directly from the GHA Workflow-Run(s).
+  - Occasionally create and publish versioned releases.
+
+## Releases and Build Artifacts
+
+Using released or CI-built artifacts can be convenient when you
+do not actually want to nor need to manually build
+`gcc-v850-unknown-elf` toolchain.
+
+Releases and build artifacts consisting of the
+fully-built `gcc-v850-unknown-elf` toolchain are occasionally created
+and published for `x86_64-linux-gnu` (Linux) and
+`x86_64-w64-mingw32` (Windows). These can be readily found
+on the repo front page and in CI workflow-run download-areas
+for immediate client use. The releases are permanent, whereby
+the built artifacts are limited to three days after the
+Workflow-Run(s).
 
 ## Workflow-Run
 
 Workflow:
-  - The Workflow-Run [gcc-v850-unknown-elf-build-msys2.yml](./.github/workflows/gcc-v850-unknown-elf-build-msys2.yml) and its associated shell script [gcc-v850-unknown-elf-100-my_ver_x86_64-w64-mingw32.sh](./gcc-v850-unknown-elf-100-my_ver_x86_64-w64-mingw32.sh) build `gcc-v850-unknown-elf` for the _host_ `x86_64-w64-mingw32`. These run on a GHA `windows-latest` runner using `msys2`.
-  - When building for `x86_64-w64-mingw32` on `msys2`, use a pre-built, dependency-free, statically linked `mingw` and host-compiler (see notes below). This separate `mingw` package is unpacked in a directory parallel to the runner workspace and its `bin` directory is added to the `PATH` variable.
+  - Use the shell script [avr-gcc-100.sh](./avr-gcc-100.sh) consistently in each of the Workflow-Run(s).
+  - The Workflow-Run [build-ubuntu.yml](./.github/workflows/build-ubuntu.yml) builds `avr-gcc` for the _host_ `x86_64-linux-gnu`. The script is executed on a GHA `ubuntu-latest` runner.
+  - The Workflow-Run [build-msys64.yml](./.github/workflows/build-msys64.yml) builds `avr-gcc` for the _host_ `x86_64-w64-mingw32`. The script is executed on a GHA `windows-latest` runner using `msys64`.
+  - When building for `x86_64-w64-mingw32` on `msys64`, use a pre-built, dependency-free, statically linked `mingw` and host-compiler (see notes below). This separate `mingw` package is unpacked in a directory parallel to the runner workspace and its `bin` directory is added to the `PATH` variable.
   - GCC prerequisites including [GMP](https://gmplib.org), [MPFR](https://www.mpfr.org), [MPC](https://www.multiprecision.org), etc. are built on-the-fly in the Workflow-Run.
   - Build [`binutils`](https://www.gnu.org/software/binutils) and partially verify the build artifacts.
-  - Then build `gcc-v850-unknown-elf` (use [newlib](https://sourceware.org/newlib) and the `--with-newlib` configuration flag) and partially verify the build artifacts.
+  - Then build `gcc-v850-unknown-elf` and partially verify the build artifacts. Use [newlib](https://sourceware.org/newlib) and the `--with-newlib` configuration flag.
   - Test the complete, newly built `gcc-v850-unknown-elf` toolchain with a non-trivial compiler test. In the compiler test, we build `ref_app` (the reference application) from [`ckormanyos/real-time-cpp`](https://github.com/ckormanyos). Verify the creation of key build results from `ref_app` including ELF-file, HEX-file, map files, etc.
 
-## Distribution
-
-Build artifacts are compressed and stored as ZIP-archive(s)
-directly from the Workflow-Run on GHA.
-The [`actions/upload-artifact`](https://github.com/actions/upload-artifact) action
-is used for archiving build artifacts.
