sure , most important every thing must be sterile if not beer will go bad , i assume its a can ? heat up some water in a pan remove from heat put can in water for 5 mins or more to make toffee like liquid(extract)in can runny , boil some more water about a litre or so and add about 1kg of sugar (on another brew after you've read up on this best to use dried malt extract instead of sugar but for now...sugar) to boiling water stir and dissolve boil for a few mins more then add to fermentation vessel (plastic bucket with lid and airlock) open can with a sterile can opener pour liquid into bucket also boil about another 4 litres of boiling water and refill can to swill remaining liquid put into bucket along with remaining water give it a good stir then add cold water upto 23 litres stir very well making bubbles check temp if around 20 ish degrees i you have 1 do a hydrometer reading (place into bucket and record what it says on hydrometer at water level)or less open yeast sprinkle into bucket fasten lid with air lock (add water into air lock to work) leave somewhere around 18oC for a least a week or more . this will do for now ask again when ready.hope this helps
