I could add them to the codestart guide.

Here is the list of dynamic configs:

gen-info.time: time of generation (in millis)
input.selected-extensions[].name|description|guide: list of selected extensions with info
input.selected-extensions-ga: Set of String with the list of extensions groupId:artifactId, usefull for dynamic codestarts depending on selected extensions
input.provided-code[].name|tags|title|description|related-guide: list of selected codestarts with info

The list of static configs is here:
