# Installation and login

You can install the Pennylane-QI plugin using pip. In case you want to install the plugin using Conda and want to access the Quantum Inspire API, refer to the section below.

```bash
pip install pennylane-quantuminspire
```

For access to the Quantum Inspire API you can use the QI tool. Once installed (see [repository](https://github.com/QuTech-Delft/quantuminspire) for installation instructions), run the shell command below to log in to the production environment.

```bash
qi login
```

## Installation in Conda

You can easily create a Conda environment that automatically comes with `quantuminspire` and `pennylane-quantuminspire` installed by using an `environment.yml` file.

Check you Conda version with `conda --version`, then run the appropriate command:

Conda >= 26.3:

```bash
conda create --file https://conda.quantum-inspire.com/pennylane.yml
```

Conda < 26.3:

```bash
conda env create --file https://conda.quantum-inspire.com/pennylane.yml
```

By default, the environment that will be created will be named `pennylane-qi`; use the `-n/--name <CUSTOM-ENV-NAME>` option to overwrite this.

After creating the environment, you need to activate it (use your custom environment name if you have defined it):

```bash
conda activate pennylane-qi
```

> **Note:** Note that due to dependency conflicts, an older version of the plugin might be installed. You can check the version using `pip show pennylane-quantuminspire` from the Conda environment.
