1st vs. repeated run experience of `prisma generate`

When starting out with Prisma, it’s helpful to provide more context to the users in CLI output. That CLI output becomes superfluous after a while.

One example is the prisma generate command which has this output:

[✔ Created `./package.json`]
[✔ Installed the `@prisma/client` package in your project]
✔ Generated Prisma Client to ./node_modules/@prisma/client in 1.48s

You can now start using Prisma Client in your code:

```
import { PrismaClient } from '@prisma/client'
// or const { PrismaClient } = require('@prisma/client')

const prisma = new PrismaClient()
```

The helpful import snippet is probably not as valuable any more once you ran the command a few times. So we might want to think of a mechanism how to remove it for later invokations.

I think in the past, why we didn’t want to do that might be that prisma generate is called on postinstall so in this case you might never see this help message because the directory would already exists, before the user actually runs the generate command.

To check and decide if we consider this a problem or not.

What about displaying it only when the client generation output directory did not previously exist and had to be created?

In that case, the message would only be displayed on initial installation (possible new user), if the output directory setting gets changed (therefore imports need to be updated), or if someone has deleted everything and is starting from scratch (something possibly went wrong with their configuration).

If the directory does exist, it’s a very good sign that the user has already set things up. Plus the default client import location is described in multiple places in the docs.
