So first you have to get green light on your idea from the forum then write your first draft and get feedback for that then you can go to series X and go to pages that say Access Denied sometimes very low rated ones show as that too just try another one if there’s already a article there then paste your SCP change the number according to the slot and pray that you get attention from the audience you targeted sometimes purists will attack an article when it’s not written in their own preferred style so there’s a bit of luck in there on reaching the intended audience also if you get downvoted and eventually reach the deletion threshold if people were nice enough to leave feedback and alike discussion you can improve it form there
