Ddeng mlynedd yn ôl, cyhoeddwyd y canllawiau gwreiddiol ar weithredu mesurau a siarteri meithrin cysylltiadau, 'Cymuned ar y Cyd', ar gyfer awdurdodau lleol a chynghorau cymuned a thref. Roedd y canllawiau hynny'n ffrwyth ymchwil a chydweithredu rhwng Llywodraeth y Cynulliad ar y pryd, Un Llais Cymru, Cymdeithas Llywodraeth Leol Cymru, Cymdeithas Clercod Cynghorau Lleol, a chynrychiolwyr o gynghorau cymuned a thref ac awdurdodau lleol.
The original guidance on relationship building measures and charters: ‘A Shared Community’ was issued ten years ago to both local authorities and community and town councils.  This guidance was the result of research and collaboration between the then Assembly Government, One Voice Wales, Welsh Local Government Association, Society of Local Council Clerks and representatives from community and town councils and local authorities.
