You mean you'd like help on how to use PokeRNG? If you didn't abuse for your ID/SID, chances are your shiny spreads are not that good. That said, the next part is totally up to you:
1) Pick what IV range you want your capture to have. Since you didn't abuse for your ID/SID don't pick all 30/31 since chances are you won't find it. Be a bit open to your IV range, ie I'd pick 25 in all stats for example and then try to narrow it down.
To do this open PokeRNG:
Nature: Leave Blank and hit enter
Hidden power: Leave blank and hit enter
Search for Exact IV: N
On all subsequent stats, you can put 25 or whatever number you like. The number you input is the smallest number PokeRNG searches for. So if youput 25 in, it wll search for 25,26,27,28,29,30,and 31.
Open up the spreadsheet and enjoy, lol.
Congratulations on your success in breeding :)
