Steps
Call FindOrCreateLeaderboard (v2) with appid, name, sortmethod, and displaytype to obtain or create a leaderboardid
Set onlytrustedwrites=true when creating the leaderboard if scores must only ever be written server-side
Use SetLeaderboardScore with scoremethod set to KeepBest or ForceUpdate to post a score for a given steamid
Query GetLeaderboardEntries with rangestart/rangeend and datarequest (RequestGlobal, RequestAroundUser, or RequestFriends) to read entries
Use DeleteLeaderboardScore or ResetLeaderboard for moderation and season-reset workflows
Known gotchas
Every ISteamLeaderboards method requires a Steamworks Web API publisher key and must be called from a secure server; none of these calls are safe to expose to a game client
GetLeaderboardsForGame and FindOrCreateLeaderboard have superseded v1 versions retained only for compatibility — use v2
