Create a package to import the repository.
Importing the project with abapGit (documentation) will generate the corresponding services, which you need to activate with Maintain Service transaction (/IWFND/MAINT_SERVICE) and assign the alias.
Import also creates a BC Set ZTT_CONFIG, importing it will generates the semantic object entry in /UI2/V_SEMOBJC and creates the Fiori catalog and group ZTASKS_TRACKER with corresponding tiles and target mappings.
