 ### Prerequisites
 
 1. **Install Llama Stack**:
-   ```bash
-   pip install llama-stack
-   ```
 
-2. **Install Provider Dependencies** (as needed):
-   ```bash
+    Using pip:
+    ```bash
+    pip install llama-stack
+    ```
 
-   # For vector operations
-   pip install faiss-cpu
+    Using uv (alternative):
+    ```bash
+    # Initialize a new project (if starting fresh)
+    uv init
 
-   # For database operations
-   pip install sqlalchemy aiosqlite asyncpg

+    # Add llama-stack as a dependency
+    uv add llama-stack
+
+    # Note: If using uv, prefix subsequent commands with 'uv run'

+#### Advanced: Custom Provider Selection (Step 1.a)
+
+If you know the specific providers you want to use, you can supply them directly on the command-line instead of using a pre-built distribution:
+
+```bash
+llama stack build --providers inference=remote::ollama,agents=inline::meta-reference,safety=inline::llama-guard,vector_io=inline::faiss,tool_runtime=inline::rag-runtime --image-type venv --image-name custom-stack
+```
+
+**Discover Available Options:**
+
+```bash
+# List all available APIs
+llama stack list-apis
+
+# List all available providers
+llama stack list-providers
+```
+
+This approach gives you complete control over which providers are included in your stack, allowing for highly customized configurations tailored to your specific needs.

 ### Select Available Distributions
 
-- **dell**: Dell's distribution for Llama Stack.
-- **open-benchmark**: Distribution for running open benchmarks.
-- **watsonx**: For IBM Watson integration.
-- **starter**: Basic distribution with essential providers.
+- **ci-tests**: CI tests for Llama Stack
+- **dell**: Dell's distribution of Llama Stack. TGI inference via Dell's custom container
+- **meta-reference-gpu**: Use Meta Reference for running LLM inference
+- **nvidia**: Use NVIDIA NIM for running LLM inference, evaluation and safety
+- **open-benchmark**: Distribution for running open benchmarks
+- **postgres-demo**: Quick start template for running Llama Stack with several popular providers
