+## Local installation
+
+https://unofficial-builds.nodejs.org/download/ hosts compressed archives that may be downloaded and installed by end-users. Each downloadable archive contains bin/, include/, lib/, share/ directories. There are different ways to install nodejs from the compressed files. Choose one of these methods below.
+
+For frequent production use, please mirror the executables to your own servers.  
+
+1. Manually unzip the archive into /usr/local/, thereby creating the various directories such as bin/, lib/, etc. (Note that this will include extraneous files at the top-level, including CHANGELOG.md, README.md and LICENSE).  
+or  
+2. Github Actions example: https://github.com/dixyes/ghactionsplay/blob/main/.github/workflows/glibc217node20.yml  
+or  
+3. (experimental). Download install-node.sh from https://gist.github.com/rvagg/742f811be491a49ba0b9 . Examine and modify the script as needed. Contributions are welcome. The script could be added to this repository in the future.  
+or  
+4. (experimental). `nvm` method. The general idea with `nvm` is this will install the software:
+```
+NVM_NODEJS_ORG_MIRROR=https://unofficial-builds.nodejs.org/download/release nvm install 12
+```
+However, `nvm` is looking for an exactly named file which it may not always find.  
+`node-v20.9.0-linux-x64.tar.gz` instead of `node-v20.9.0-linux-x64-glibc-217.tar.gz`.
+Therefore a possible idea is to create a mirror of https://unofficial-builds.nodejs.org/download/release such as https://www.example.com/download/release, including files index.json and index.tab. Rename archives in the mirror so `nvm` will recognize them. For example, copy `node-v20.9.0-linux-x64-glibc-217.tar.gz` to `node-v20.9.0-linux-x64.tar.gz`. Then an installation would succeed:  
+```
+NVM_NODEJS_ORG_MIRROR=https://www.example.com/download/release nvm install v20.9.0 
+```
