# The `stack templates` command ~~~text stack templates ~~~ `stack templates` provides information about project templates used with the [`stack new` command](new_command.md). Project templates are specified in `.hsfiles` files. The format of those files is documented at the [`commercialhaskell/stack-templates`](https://github.com/commercialhaskell/stack-templates#project-template-format) repository on GitHub. Any GitHub, GitLab or Bitbucket repository named `stack-templates` can provide project template files. For example, a template file `username/stack-templates/my-template.hsfiles` on GitHub can be identified as `username/my-template` when using `stack new`. The relevant service can be specified by a prefix: `github:` for [GitHub](https://github.com/) (the default service), `gitlab:` for [GitLab](https://gitlab.com), or `bitbucket:` for [Bitbucket](https://bitbucket.com). [`commercialhaskell/stack-templates`](https://github.com/commercialhaskell/stack-templates#project-template-format) on GitHub is the default repository for project templates. Its username (`commercialhaskell`) does not need to be specified when using `stack new`. The project template that `stack new` uses by default is named `new-template` and provided at the default repository. The default repository provides 24 other project templates. Its Wiki provides a description of some of those templates and information about the location of other templates.
