+## Shell Alias
+
+To use `gnmi-eos` directly without installing it, add this alias to your shell config (`~/.bashrc`, `~/.zshrc`, etc.):
+
+```bash
+alias gnmi-eos='uvx --from git+https://gitea.arnodo.fr/Damien/gnmi-eos gnmi-eos'
+```
+
+Then reload your shell:
+
+```bash
+source ~/.zshrc  # or ~/.bashrc
+```
+
+You can now use `gnmi-eos` as if it were installed:
+
+```bash
+gnmi-eos --help
+gnmi-eos capabilities --target leaf1:6030
+gnmi-eos subscribe --target leaf1:6030 --path "/interfaces/interface/state/counters" --mode sample
+```
