 ### Security Notice
 
-This script relies on external binaries in order to complete the performance tests. The network (iperf3) and disk (fio) tests use binaries that are compiled by myself utilizing a [Holy Build Box](https://github.com/phusion/holy-build-box) compilation environment to ensure binary portability. The reasons for doing this include ensuring standardized (parsable) output, allowing support of both 32-bit and 64-bit architectures, bypassing the need for prerequisites to be compiled and/or installed, among other reasons. For the system test, a Geekbench tarball is downloaded, extracted, and the resulting binary is run. Use this script at your own risk as you would with any script publicly available on the net. Additional information regarding the binaries, including compilation notes and steps, can be found in the bin directory's [README page](bin/README.md).

 ## YABS Pre-Compiled Binaries
 
-This directory contains all of the binaries required to run the benchmarking tests. Naturally, there is a security risk to your machine and its contents by running this script since, after all, this is just a script on the internet. You'll simply have to have confidence that I don't have malicious intent and am semi-competent at writing a bash script. The script is made public so you can look at the code yourself. The binaries were compiled using a [Holy Build Box](https://github.com/phusion/holy-build-box) compilation environment in order to ensure the most portability. The compiled binary version numbers and compilations steps are noted below. Please open an issue if the compiled version is out of date and lacking any security-related and/or performance updates.

-Note: ARM compatibility is considered experimental. Static binaries for 32-bit and ARM-based machines are cross-compiled within a Holy Build Box container using the [musl toolchain](https://musl.cc/).
+At runtime, yabs.sh auto-detects the latest `fio-*`/`iperf3-*` release via the
+repository's releases feed and downloads the appropriate binary for the host
+architecture. If the lookup fails, it falls back to a pinned release tag.
 
-### Compile Notes
+Naturally, there is a security risk to your machine and its contents by running
+this script since, after all, this is just a script on the internet. You'll
+simply have to have confidence that I don't have malicious intent and am
+semi-competent at writing a bash script. The script and the workflows that build
+the binaries are public so you can look at the code yourself. The binaries are
+compiled using a [Holy Build Box](https://github.com/phusion/holy-build-box)
+compilation environment in order to ensure the most portability. Please open an
+issue if the binaries are out of date and lacking any security-related and/or
+performance updates - the daily scheduled workflows should pick up new upstream
+releases automatically.
+
+Note: RISC-V compatibility is considered experimental.
+
+### Compile Notes (manual builds)

+The workflows above are the canonical build path. To build manually, the same
+scripts can be run inside a Holy Build Box container:

 ### Cross-compiling Notes
 
-Compilation of ARM-compatible binaries requires additional environment variables to identify the proper musl toolchain and architecture to target for cross-compilation.
+Compilation of 32-bit and ARM-compatible binaries requires additional
