 Similar to `yarn create` and `npm create`, PDM also supports initializing or creating a project from a template.
 The template is given as a positional argument of `pdm init`, in one of the following forms:
 
-- `pdm init flask` - Initialize the project from the template `https://github.com/pdm-project/template-django`
+- `pdm init django` - Initialize the project from the template `https://github.com/pdm-project/template-django`
 - `pdm init https://github.com/frostming/pdm-template-django` - Initialize the project from a Git URL. Both HTTPS and SSH URL are acceptable.
 - `pdm init django@v2` - To check out the specific branch or tag. Full Git URL also supports it.
 - `pdm init /path/to/template` - Initialize the project from a template directory on local filesystem.
