1. I have created a project called vsr-bas
2. Within the project I have created a Step Template called build. It has one parameter and works fine.
3. I have a child project atteched to vsr-bas: vsr-map
4. I now want to Import the Step Template from the parent project vsr-bas into its child vsr-map

So:

1. in vsr-map I modify the .onedev-buildspec.yml file > Imports tab
2. I click the Plus/+ button > the import interface is displayed
3. I select vsr-bas in the local menu
4. but as soon as I click into the Tag field, I get an error message:

Which is actually true (no properties were defined in vsr-bas) but I thought imports also encompassed Step Templates as explained in the help bubble:

Import build spec elements (jobs, services, step templates and properties) from other projects.

What am I doing wrong?

Also, could you direct me to a comprehensive documentation on Templates as I can't find it on the site.

Best, Stephen
