+# Using TGI CLI
+
+You can use TGI command-line interface (CLI) to download weights, serve and quantize models, or get information on serving parameters. To install the CLI, please refer to [the installation section](./installation#install-cli).
+
+`text-generation-server` lets you download the model with `download-weights` command like below 👇 
+
+```bash
+text-generation-server download-weights MODEL_HUB_ID
+```
+
+You can also use it to quantize models like below 👇 
+
+```bash
+text-generation-server quantize MODEL_HUB_ID OUTPUT_DIR 
+```
+
+You can use `text-generation-launcher` to serve models. 
+
+```bash
+text-generation-launcher --model-id MODEL_HUB_ID --port 8080
+```
+
+There are many options and parameters you can pass to `text-generation-launcher`. The documentation for CLI is kept minimal and intended to rely on self-generating documentation, which can be found by running 
+
+```bash
+text-generation-launcher --help
+``` 
+
+You can also find it hosted in this [Swagger UI](https://huggingface.github.io/text-generation-inference/).
+
+Same documentation can be found for `text-generation-server`.
+
+```bash
+text-generation-server --help
