For more information, view the [Azure Quantum Documentation](https://learn.microsoft.com/en-us/azure/quantum/).
 
 This package supports submitting quantum programs or circuits written with Python. To submit quantum programs written with Q#, Microsoft's Domain-specific language for Quantum Programming, view [Submit Q# Jobs to Azure Quantum](https://learn.microsoft.com/azure/quantum/how-to-submit-jobs).
 
 ## Installation ##
 
 The package is released on PyPI and can be installed via `pip`:
 
-```bash
-pip install azure-quantum
-```
-
-To use `azure-quantum` for submitting quantum circuits expressed with [Qiskit](https://pypi.org/project/qiskit), install with optional dependencies:
-
-```bash
-pip install azure-quantum[qiskit]
-```
-
-To use `azure-quantum` for submitting quantum circuits expressed with [Cirq](https://pypi.org/project/cirq), install with optional dependencies:
-
-```bash
-pip install azure-quantum[cirq]
-```
+- For default installation - `pip install azure-quantum`
+- Submit quantum circuits written in [Q#](https://pypi.org/project/qsharp) - `pip install azure-quantum[qsharp]` 
+- Submit quantum circuits written in [Qiskit](https://pypi.org/project/qiskit) - `pip install azure-quantum[qiskit]`
+- Submit quantum circuits written in [Cirq](https://pypi.org/project/cirq) - `pip install azure-quantum[cirq]`

-## Development Setup ##
-
-For developers who want to contribute to this package or run tests locally, follow these steps:
-
-### Prerequisites
-
-- Python 3.9 or later
-- Git
-- Powershell
-
-### Setting up the development environment
-
-1. Clone the repository:
-   ```bash
-   git clone https://github.com/microsoft/qdk-python.git
-   cd qdk-python/azure-quantum
-   ```
-
-2. Set up a virtual environment and install development dependencies:
-   ```powershell
-   # On Windows (PowerShell)
-   .\eng\Setup-Dev-Env.ps1
-   ```
-
-3. Run the tests:
-   ```bash
-   pytest tests/unit/
-   ```
-
-4. (Optional) Install additional provider dependencies:
-   ```bash
-   # For specific providers
-   pip install -e .[pulser,quil]
-
-   # For all providers (requires Rust toolchain for PyQuil)
-   pip install -e .[all]
-   ```
-
-### Running Tests
-
-The development environment includes pytest for running unit tests. See [tests/README.md](tests/README.md) for detailed testing instructions.
+You can find example Python scripts that use the Azure Quantum Python API in the [samples](https://github.com/microsoft/azure-quantum-python/tree/main/samples) directory.

-- You're logged into your Azure Entra ID Tenant in the Azure CLI - `az login` (or `az login --tenant <tenantId>`).

+- The client app is configured with [certificate-based authentication](https://learn.microsoft.com/en-us/entra/identity/authentication/how-to-certificate-based-authentication)
+- The client app has "Contributor" permissions to your Azure Quantum Workspace
 - You have "Quantum Workspace Owner" or "Quantum Workspace Data Contributor" or "Contributor" role on the Azure Quantum Workspace against which you would like to capture the recordings.
 - You have all necessary Providers added to the Azure Quantum Workspace.
 - The following environment variables are set:
+  - `AZURE_CLIENT_ID` - application (client) ID from Microsoft Entra ID
+  - `AZURE_TENANT_ID` - directory (tenant) ID from Microsoft Entra ID
+  - `AZURE_CLIENT_CERTIFICATE_PATH` - path to PEM or PKCS12 certificate file (including the private key) that is configured for the client app
+  - `AZURE_CLIENT_SEND_CERTIFICATE_CHAIN=True` - prompts Azure.Identity to set X5C header (specifying certificate chain) required to support SNI authentication
