### Virtual environment

Follow the instructions to create and activate a [virtual environment](virtual-environments.md){.internal-link target=_blank} for the internal code of `fastapi`.

### Install requirements using pip

After activating the environment, install the required packages:

installed we may want to check the license and make users agree. We may also want to unpack the given plugin in a particular location.

We might want to separate between installation and activation, it might be nice to allow a user to activate/deactivate a plugin instead of having to uninstall and reinstall a plugin in particular cases. This would prevent having to reconfigure the plugin again. For example it might be nice to turn off LDAP authentication without having to uninstall the plugin....

## Install `SQLModel`

First, make sure you create your [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>
