## CR line breaks found [Windows]

This is due to the linebreak characters of Windows and the git configuration. Try running:
```
git config --global core.autocrlf false
```

Then delete the repository and clone it again.

## Extra yarn files are created

If you have extra files created by yarn  (`yarn.lock`, `.yarnrc.yml`, `.yarn`), you may have a yarn version issue.
Try installing [yarn classic](https://classic.yarnpkg.com/lang/en/)!

## Missing metadata schema

During Twenty installation, your postgres database needs to be provisioned with right schemas, extensions and users.
We provide [different ways](/contributor/local-setup/yarn-setup#step-2-set-up-postgresql-database) to set up your postgres instance.

If you sucessfully run this provisioning, you should have `default` and `metadata` schemas in your database.
If you don't, make sure you don't have multiple postgres instance running on your computer.
