 > **Auto-download:** On install, the binary for your platform is downloaded automatically. Use `--foreground-scripts` to see the progress bar.
 
-### Global Install (Recommended)
+### 🪟 Windows — Global Install
 
 ```bash
 npm install -g @chahuadev/chahuadev-hub-app --foreground-scripts --force
 ```
 
-### Launch
+### 🐧 Linux — Global Install
+
+Linux requires `sudo` for global npm packages:
+
+```bash
+sudo npm install -g @chahuadev/chahuadev-hub-app --foreground-scripts --force
+```
+
+> **Alternative (no sudo required):** Set npm prefix to your home folder first:
+> ```bash
+> mkdir -p ~/.npm-global
+> npm config set prefix '~/.npm-global'
+> echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
+> source ~/.bashrc
+> ```
+> Then install without sudo:
+> ```bash
+> npm install -g @chahuadev/chahuadev-hub-app --foreground-scripts --force
+> ```
+
+### 🚀 Launch
+
+```bash
+chahuadev-hub
+```
+

+
+## �️ Troubleshooting
+
+### ENOTEMPTY error on Linux (directory not empty)
+
+If you see `ENOTEMPTY` during install, a previous failed install left files behind. Clear them first:
+
+```bash
+# If installed with npm-global prefix
+rm -rf ~/.npm-global/lib/node_modules/@chahuadev/chahuadev-hub-app
+npm install -g @chahuadev/chahuadev-hub-app --foreground-scripts --force
+
+# If installed with sudo
+sudo rm -rf /usr/lib/node_modules/@chahuadev/chahuadev-hub-app
+sudo npm install -g @chahuadev/chahuadev-hub-app --foreground-scripts --force
+```
+
+### Executable not found after install
+
+If `chahuadev-hub` command is not found after install, make sure `~/.npm-global/bin` is in your PATH:
 
 ```bash
+echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
+source ~/.bashrc
 chahuadev-hub
 ```
