Template Projects

Is there a proper way to add/change the default list of templates? How can I add additional ones

There is a table in the database called d_b_repository_white_list. You can change these entries there. See: https://github.com/gitpod-io/gitpod/blob/623d438ded025b5137344db915c4bb790eb4d826/components/gitpod-db/src/typeorm/migration/1612448906950-ExampleRepositories.ts
