 **unofficial-builds** attempts to provide basic Node.js binaries for some platforms that either not supported or only partially supported by Node.js. This project **does not provide any guarantees** and its results are not rigorously tested. Builds made available at nodejs.org have very high quality standards for code quality, support on the relevant platforms and for timing and methods of delivery. Builds made available by unofficial-builds have minimal or no testing; the platforms may have no inclusion in the official Node.js test infrastructure. These builds are made available for the convenience of their user community but those communities are expected to assist in their maintenance.
 
+## Run
+
+Execute the following commands to cross compile riscv64 node binaries. Select the node version on the `bin/build.sh` call.
+
+```sh
+./bin/prepare-images.sh "fetch-source riscv64"
+mkdir -p build/download
+mkdir -p build/logs
+mkdir -p build/staging
+mkdir -p build/.ccache
+workdir=$PWD/build/ bin/build.sh v18.16.0 riscv64
+```
+
 ## Builds
 
  * **linux-x64-musl**: Linux x64 binaries compiled against [musl libc](https://www.musl-libc.org/) version 1.1.20. Primarily useful for users of Alpine Linux 3.9 and later. Linux x64 with musl is considered "Experimental" by Node.js but the Node.js test infrastructure includes some Alpine test servers so support is generally good. These Node.js builds require the `libstdc++` package to be installed on Alpine Linux, which is not installed by default. You can add this by running `apk add libstdc++`.
+* **linux-x64-glibc-217**: Linux x64, compiled with glibc 2.17 to support [older Linux distros](https://en.wikipedia.org/wiki/Glibc#Version_history), QNAP QTS 4.x and 5.x, and Synology DSM 7, and other environments where a newer glibc is unavailable.
  * **linux-x86**: Linux x86 (32-bit) binaries compiled against libc 2.17, similar to the way the official [linux-x64 binaries are produced](https://github.com/nodejs/node/blob/master/BUILDING.md#official-binary-platforms-and-toolchains). 32-bit Linux binaries were dropped for Node.js 10 and 32-bit support is now considered "Experimental".
  * **linux-armv6l**: Linux ARMv6 binaries, cross-compiled on Ubuntu 16.04 with a [custom GCC 6 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js versions earlier than 16) or Ubuntu 18.04 with a [custom GCC 8 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js 16 and later) in a similar manner to the official linux-armv7l binaries. Binaries are optimized for `armv6zk` which is suitable for Raspberry Pi devices (1, 1+ and Zero in particular). ARMv6 binaries were dropped from Node.js 12 and ARMv6 support is now considered "Experimental".
- * **riscv64**: Linux riscv64 (RISC-V), cross compiled on Ubuntu 20.04 with the toolchain which the Adoptium project uses (for  now...). Built with --openssl-no-asm (Should be with --with-intl=none but that gets overriden)
+ * **riscv64**: Linux riscv64 (RISC-V), cross compiled on Ubuntu 22.04 with the ubuntu toolchain. Built with --openssl-no-asm (Should be with --with-intl=none but that gets overriden)
 
 "Experimental" status for Node.js is defined as:
 > Experimental: May not compile or test suite may not pass. The core team does not create releases for these platforms. Test failures on experimental platforms do not block releases. Contributions to improve support for these platforms are welcome.

 1. This repository is cloned onto the unofficial-builds server whenever it is updated (triggered via [github-webhook](https://github.com/rvagg/github-webhook)) and Docker images contained within the [`/recipes`](/recipes) directory are built by means of the [`/bin/deploy.sh`](/bin/deploy.sh) script which in turn calls the [`/bin/prepare-images.sh`](/bin/prepare-images.sh) script.
 2. A periodic service runs every 5 minutes via systemd on the server which calls [`/bin/periodic.sh`](/bin/periodic.sh) script.
-3. `periodic.sh` calls [`/bin/check-releases.sh`](/bin/check-releases.sh) for each release line being checked ("release", "rc", etc.). Any new versions that check-releases.sh finds are added to the build queue via [`/bin/queue-push.sh`](/bin/queue-push.sh) (the build queue uses a locking mechanism to prevent concurrent changes). 
+3. `periodic.sh` calls [`/bin/check-releases.sh`](/bin/check-releases.sh) for each release line being checked ("release", "rc", etc.). Any new versions that check-releases.sh finds are added to the build queue via [`/bin/queue-push.sh`](/bin/queue-push.sh) (the build queue uses a locking mechanism to prevent concurrent changes).
 4. `periodic.sh` calls [`/bin/build-if-queued.sh`](/bin/build-if-queued.sh) which will execute a build if there is at least one build in the queue and no builds are currently running. [`/bin/queue-pop.sh`](/bin/queue-pop.sh) is used to atomically remove the next build from the queue. Note that only zero or one build per periodic run is executed. If the queue has more than one build, these will be deferred until later periodic runs.
 5. When `build-if-queued.sh` encounters a build in the queue that it can execute, it calls [`/bin/build.sh`](/bin/build.sh) to perform the build. This script iterates through the images that have been pre-built from the [`/recipes`](/recipes) directory, starting with the [`/recipes/fetch-source`](/recipes/fetch-source) recipe that fetches the source file for the given version and validates official releases using GPG keys. Optionally, a recipe might have a `should-build` file which is used to determine if the recipe should run for a specific Node.js version. Each recipe is passed this source and is given a staging directory to place its binaries in. After all recipes are finished, builds are promoted to the <https://unofficial-builds.nodejs.org/download/> directory along with a SHASUMS256.txt file and the index.tab and index.json files for that release type are updated.
