Discourse markers

Discourse markers link one idea to another in speech or writing. They clarify the relationship between these ideas for listeners or readers: structuring and sequencing (e.g. first of all),adding information (e.g. moreover), showing your attitude (e.g.frankly), pointing out a contrast (e.g.Despite, however) concluding (e.g.In conclusion, to sum up). Would anyone have an extensive list of discourse markers?
