+	// the game phase should be a section of gameplay that is usually between 10 minutes and a few hours in length, and should be the
+	// main way a user would think to divide up the game. These are presented to the user in a UI that shows the date the game was played,
+	// with one row per game slice. Game phases should be used to mark sections of gameplay that the user might be interested in watching.
+	//
+	//	Examples could include:
+	//		* A single match in a multiplayer PvP game
+	//		* A chapter of a story-based singleplayer game
+	//		* A single run in a roguelike
+	//
+	// Game phases are started with StartGamePhase, and while a phase is still happening, they can have tags and attributes added to them.
+	//
+	// Phase attributes represent generic text fields that can be updated throughout the duration of the phase. They are meant
+	// to be used for phase metadata that is not part of a well defined set of options. For example, a KDA attribute that starts
+	// with the value "0/0/0" and updates as the phase progresses, or something like a played-entered character name. Attributes
+	// can be set as many times as the game likes with SetGamePhaseAttribute, and only the last value will be shown to the user.
+	//
+	// Phase tags represent data with a well defined set of options, which could be data such as match resolution, hero played,
+	// game mode, etc. Tags can have an icon in addition to a text name. Multiple tags within the same group may be added per phase
+	// and all will be remembered. For example, AddGamePhaseTag may be called multiple times for a "Bosses Defeated" group, with
+	// different names and icons for each boss defeated during the phase, all of which will be shown to the user.
+	//
+	// The phase will continue until the game exits, until the game calls EndGamePhase, or until the game calls
+	// StartGamePhase to start a new phase.
+	//
+	// The game phase functions take these parameters:
+	// - pchTagIcon: The name of a game provided timeline icon or builtin "steam_" icon.
+	// - pchPhaseID: A game-provided persistent ID for a game phase. This could be a the match ID in a multiplayer game, a chapter name in a
+	//   single player game, the ID of a character, etc.
+	// - pchTagName: The localized name of the tag in the language returned by SteamUtils()->GetSteamUILanguage().
+	// - pchTagGroup: The localized name of the tag group.
+	// - pchAttributeValue: The localized name of the attribute.
+	// - pchAttributeGroup: The localized name of the attribute group.
