Alright, I triggered a build:

Jenkins: https://ci.cfengine.com/job/fast-build-and-deploy-docs-master/144/

Documentation: http://buildcache.cfengine.com/packages/build-documentation-pr/jenkins-fast-build-and-deploy-docs-master-144/output/_site/

What issue is this fixing? I checked a few anchors and they looked OK and seemed to work.

What issue is this fixing? I checked a few anchors and they looked OK and seemed to work.

For example: https://docs.cfengine.com/docs/master/reference/promise-types/services/

the link takes you to the top of the page instead of to the anchor

This pr fixes the link to the anchor: http://buildcache.cfengine.com/packages/build-documentation-pr/jenkins-fast-build-and-deploy-docs-master-144/output/_site/reference/promise-types/services/

Notice that it links to reference/special-variables/this/#thispromiser instead of reference/special-variables/this#this-promiser
