+The website is deployed with a pipeline that goes through Jenkins, this is because we do not want an ssh key to the production server on github.
 Jenkins can be accessed on [jenkins.dsek.se](https://jenkins.dsek.se), those with access can log in using the same credentials as on [dsek.se](https://dsek.se). When logged in select the view `Dsek Web` and the pipeline `Deploy_web` is the one deploying the website.

+### Debugging production database
+
+An easy way to debug something in the production database is to use an ssh-tunnel which allows you to view the database with any database tool you want. Make sure to **never** run `pnpm seed` or similar destructive commands when having a tunnel open. You can open the tunnel with the following command:
+
+```bash
+ssh -N stil-id@web-beta -J [email protected] -L 5432:localhost:5432
+```
+
+or, if you have the config above:
+
+```bash
+ssh -N web-beta.blossom -L 5432:localhost:5432
+```
