+# Chat commands
+
+There are not many chat commands provided by this modpack since it's primarily a mapgen mod. Only one is available to non-server-admins:
+
+`mute_df_ambience`: Mutes or unmutes ambient sounds in deep caverns. This muted state is saved per-player, so players that are bothered by ambient sounds can disable them for themselves.
+
+The following are only available for server admins:
+
+`find_pit`: Finds the nearest glowing pit in the Underworld layer.
+
+`mapgen_helper_loc` and `mapgen_helper_tour`: only available if the `mapgen_helper_log_locations` setting has been set to true. mapgen_helper will then record the locations of various types of mapgen feature as they are generated, and these commands will teleport the server admin to them.
+
+`find_pit_caves`: Lists the locations of nearby vertical shaft caverns, including the top and bottom elevations.
+	
+# APIs
+
+Not all APIs are listed here, this list focuses on APIs that modders may wish to use in sub-mods that modify DF Caverns' functionality in the existing context of this modpack.
+
+## bones_loot
+
+This mod populates the bones in the underworld with loot.
+
+`bones_loot.register_loot`
+
+Uses same table format as dungeon_loot from the default minetest_game. eg, {{name = "bucket:bucket_water", chance = 0.45, types = {"sandstone", "desert"}},
+
+if dungeon_loot is installed it uses dungeon_loot's registration function directly.
+
+## chasms
+
+`chasms.register_ignore(node_name)`: Use this to set node types to be left alone by chasm-carving
+
+`chasms.is_in_chasm(pos)`: returns true if pos is inside a chasm.
+
+## df_ambience
+
+`df_ambience.add_set(def)`: adds a sound set to the ambience mod. See soundsets.lua for a bunch of examples of what can go in the `def` table.
+
+This mod has a lot of similarities to the [https://notabug.org/TenPlus1/ambience](ambience) mod, but after struggling to get that mod to "play nice" with df_caverns' needs it turned out to be easier to just re-implement the specific parts of the mod that were needed here.
+
+## df_caverns
+
+`df_caverns.get_biome(pos)`: returns the string name of the df_cavern biome that pos is located in, or nil if it's outside of any of df_caverns' cavern layers. df_caverns uses a homebrew biome system rather than the built-in biome registration system.
+
+`df_caverns.is_ground_content(node_id)`: used by subterrane's mapgen to avoid removing nodes placed by df_caverns' mapgen. If you're adding new map features inside dfcavern's hollow spaces and they're being chopped in half at mapblock boundaries then you may be able to solve this by overriding this method with one that recognizes the nodes you're adding.
+
+This was never really expected to be something that someone would need to do, though, so this is a little clunky. If you're having trouble with this please file an issue.
+
+`df_caverns.populate_puzzle_chest(pos)`: When a "puzzle chest" is generated in the Underworld ruins this method gets called to populate its contents. If you wish to override the contents of the puzzle chest then you can override this method. Place items in the "main" inventory at the pos parameter's location.
+
+## looped_node_sound
+
+`looped_node_sound.register(def)`: A simple mod for making nodes emit a looped sound when the player is nearby.
+
+  def = {
+    node_list = {"df_trees:torchspine_1_lit"},
+    sound = "dfcaverns_torchspine_loop",
+    max_gain = 0.5,
+    gain_per_node = 0.05,
+  }

 At the very foundation of the world lies an ancient impenetrable realm. There are signs that life once existed here but it is now long gone. Its dead hollows rest on a layer of Slade, a dense material impervious to conventional mining efforts.
 
+Unconventional methods of penetrating the Slade do exist, however. And should it be breached, the exotic Primordial cavern layer can be found beneath.

 ## Other Features
 
 The giant caverns generated by this mod differ slightly from the default giant caverns found in some mapgens, they use an additional source of noise to generate more ledges and horizontal floors. They also contain stalactites and stalagmites of various sizes - from single-node spikes decorating the default twisty tunnels to mountainous behemoths in the main caverns that can reach tens of meters in diameter and hundreds of meters in height.

+This mod provides a framework for adding "lore" collectibles, entries that are either a block of text or an image. Players unlock these collectibles by finding stone cairns, and view them by using a "satchel" object. Note that players are not literally carrying these collectibles, whether they've been unlocked is recorded globally and any satchel will allow them to view their collection.
+
+This is intended as a somewhat similar concept to achievements, but to reward exploration in general and to provide information about the world the player finds themself in.
+
+An example:
+
+	collectible_lore.register_lorebook({
+		id = "banks tunnels",
+		title = S("Twisting Tunnels"),
+		text = S([[Today's exploration took us deep into the caverns beneath the surface world. As we progressed, I was reminded of the intricate network of passages that make up the bedrock of this world.
+
+	It is fascinating to see how these passages have been carved by a combination of ancient streams and other mysterious processes that have yet to be fully understood. They twist and turn, making navigation a challenging task. Although it is possible to reach almost any location by following these existing passages, they can be so convoluted that it sometimes makes more sense to simply mine a direct route to your destination.
+
+	The significance of these passages cannot be overstated. They provide a glimpse into the geological history of the world and the forces that shaped it. The passages also hold the promise of valuable mineral deposits and other resources, making them a crucial area of exploration for anyone seeking to unlock the secrets of the earth.
+
+	Signed,
+	Dr. Theodore Banks]]),
+		sort = 101,
+	})
+
+The id should be a unique string, this is the key that will be recorded when a player unlocks a collectible. The title is shown in the list of collectibles when it is unlocked. The sort value is used to sort items in the collectible list in increasing order; it doesn't have to be unique, items with the same sort number will fall back to sorting by id.
+
+Instead of text, an image can be shown:
+
+	collectible_lore.register_lorebook({
+		id = "rose watercolor chasm wall",
+		title = S("Chasm Wall, By Amelia Rose"),
+		image = "df_lorebooks_chasm_wall.jpg",
+		sort = 201,
+	})
+
+Note that currently images and text are mutually exclusive, and images should have a square aspect ratio.
+
+This mod by itself currently only provides a framework and defines the cairn and satchel nodes, you'll need to provide a mapgen to insert them into your world. The ``collectible_lore.place_cairn`` method checks to see if there are nearby cairns before it goes ahead and places a cairn, preventing them from being bunched too closely together, and should prove useful.
