+# Offline Node.js 22 setup for Ubuntu 20.04
+
+This folder contains scripts to prepare and install fresh Node.js 22 without internet on target host.
+
+## Files
+
+- `prepare-online.sh` - run on internet-connected Linux machine
+- `install-offline.sh` - run on offline Ubuntu 20.04 machine
+
+## 1) On online machine
+
+```bash
+cd nodejs-offline-ubuntu2004
+chmod +x prepare-online.sh install-offline.sh
+
+# x64, latest v22
+./prepare-online.sh x64
+
+# OR arm64, latest v22
+./prepare-online.sh arm64
+
+# Optional: pin exact version
+./prepare-online.sh x64 22.15.0
+```
+
+You will get directory like:
+- `bundle-node-v22.15.0-linux-x64`
+
+Copy this directory **and** `install-offline.sh` to offline machine.
+
+## 2) On offline Ubuntu 20.04
+
+```bash
+chmod +x install-offline.sh
+sudo ./install-offline.sh ./bundle-node-v22.15.0-linux-x64
+source /etc/profile.d/nodejs.sh
+node -v
+npm -v
+```
+
+## Notes
+
+- Default install path: `/opt/nodejs`
+- Active symlink: `/opt/nodejs/current`
+- To install into custom path:
+
+```bash
+sudo INSTALL_PREFIX=/srv/nodejs ./install-offline.sh ./bundle-node-v22.15.0-linux-x64
+```
