+
+If you want to change the database platform of your Part-DB installation (e.g. from SQLite to MySQL/MariaDB or PostgreSQL, or vice versa), there is the `partdb:migrations:convert-db-platform` console command, which can help you with that:
+
+1. Make a backup of your current database to be safe if something goes wrong (see the backup documentation).
+2. Ensure that your database is at the latest schema by running the migrations: `php bin/console doctrine:migrations:migrate`
+3. Change the `DATABASE_URL` environment variable to the new database platform and connection information. Copy the old `DATABASE_URL` as you will need it later.
+4. Run `php bin/console doctrine:migrations:migrate` again to create the database schema in the new database. You will not need the admin password, that is shown when running the migrations.
+5. Run the conversion command, where you have to provide the old `DATABASE_URL` as parameter: `php bin/console partdb:migrations:convert-db-platform <OLD_DATABASE_URL>`

+   ```bash

docs/installation/email.md

@@ -15,13 +15,75 @@ To make emails work you have to properly configure a mail provider in Part-DB.
 ## Configuration
 
 Part-DB uses [Symfony Mailer](https://symfony.com/doc/current/mailer.html) to send emails, which supports multiple
-automatic mail providers (like MailChimp or SendGrid). If you want to use one of these providers, check the Symfony
+mail providers (like Mailgun, SendGrid, or Brevo). If you want to use one of these providers, check the Symfony
 Mailer documentation for more information.
 
 We will only cover the configuration of an SMTP provider here, which is sufficient for most use-cases.
 You will need an email account, which you can use to send emails from via password-based SMTP authentication, this account
 should be dedicated to Part-DB.
 
+### Using specialized mail providers (Mailgun, SendGrid, etc.)
+
+If you want to use a specialized mail provider like Mailgun, SendGrid, Brevo (formerly Sendinblue), Amazon SES, or 
+Postmark instead of SMTP, you need to install the corresponding Symfony mailer package first.
+
+#### Docker installation
+
+If you are using Part-DB in Docker, you can install additional mailer packages by setting the `COMPOSER_EXTRA_PACKAGES` 
+environment variable in your `docker-compose.yaml`:
+
+```yaml
+environment:
+  - COMPOSER_EXTRA_PACKAGES=symfony/mailgun-mailer
+  - MAILER_DSN=mailgun+api://API_KEY:DOMAIN@default
+  - EMAIL_SENDER_EMAIL=noreply@yourdomain.com
+  - EMAIL_SENDER_NAME=Part-DB
+  - ALLOW_EMAIL_PW_RESET=1
+```
+
+You can install multiple packages by separating them with spaces:
+
+```yaml
+environment:
+  - COMPOSER_EXTRA_PACKAGES=symfony/mailgun-mailer symfony/sendgrid-mailer
+```
+
+The packages will be installed automatically when the container starts.
+
+Common mailer packages:
+- `symfony/mailgun-mailer` - For [Mailgun](https://www.mailgun.com/)
+- `symfony/sendgrid-mailer` - For [SendGrid](https://sendgrid.com/)
+- `symfony/brevo-mailer` - For [Brevo](https://www.brevo.com/) (formerly Sendinblue)
+- `symfony/amazon-mailer` - For [Amazon SES](https://aws.amazon.com/ses/)
+- `symfony/postmark-mailer` - For [Postmark](https://postmarkapp.com/)
+
+#### Direct installation (non-Docker)
+
+If you have installed Part-DB directly on your server (not in Docker), you need to manually install the required 
+mailer package using composer.
+
+Navigate to your Part-DB installation directory and run:
+
+```bash
+# Install the package as the web server user
+sudo -u www-data composer require symfony/mailgun-mailer
+
+# Clear the cache
+sudo -u www-data php bin/console cache:clear
+```
+
+Replace `symfony/mailgun-mailer` with the package you need. You can install multiple packages at once:
+
+```bash
+sudo -u www-data composer require symfony/mailgun-mailer symfony/sendgrid-mailer
+```
+
+After installing the package, configure the `MAILER_DSN` in your `.env.local` file according to the provider's 
+documentation (see [Symfony Mailer documentation](https://symfony.com/doc/current/mailer.html) for DSN format for 
+each provider).

+
+### "API responded with error code: 0: Unknown"
+
+If you get this error when trying to connect KiCad to Part-DB, it is most likely caused by KiCad not trusting your SSL/TLS certificate.
+
+**Cause:** KiCad does not trust self-signed SSL/TLS certificates.
+
+**Solutions:**
+- Use HTTP instead of HTTPS for the `root_url` in your KiCad library configuration (only recommended for local networks)
+- Use a certificate from a trusted Certificate Authority (CA) like [Let's Encrypt](https://letsencrypt.org/)
+- Add your self-signed certificate to the system's trusted certificate store on the computer running KiCad (the exact steps depend on your operating system)
+
+For more information about KiCad integration, see the [EDA / KiCad integration](../usage/eda_integration.md) documentation.

+The Buerklin provider uses the [Buerklin API](https://www.buerklin.com/en/services/eprocurement/) to search for parts and get information.
+To use it you have to request access to the API.
+You will get an e-mail with the client ID and client secret, which you have to put in the Part-DB configuration (see below).
+
+Please note that the Buerklin API is limited to 100 requests/minute per IP address and 
+access to the Authentication server is limited to 10 requests/minute per IP address
