look on youtube... they have lots of vids that show step by step... i have nvr tried using oil.. i always use butter.. nvr use margrine!!! it doesnt work... boil water in a pot then add a stick of butter... reduce heat to a simmer and add ur weed when the butters melted.. use at least a 1/2 oz per stick... (i use straight trim but alot.. maybe a shoppin bag per stick.... it comes out really good none the less) boil the mixture for 45 mins, minimum... then strain the mixture(mesh strainer, dollar store) into a pot big enuff to hold the mixture... squeeze juice outta the weed threw the strainer(careful, its hot) and throw the weed away... let the water, butter mixture cool on the counter for an hr atleast so the butter can start to rise b4 it sets otherwise ur gonna have lil pieces floatin in the water.... put it in the fridge over night and then cut the butter off the top and throw the water away.. if theres chunck in the water still u can fish them out.. rinse with cold water and enjoy!!!
