+# Library *gfx.blockwraps*
+
+Library for working with *block wrappers*.
+
+Block wrappers are introduced to implement block destruction animation and can be used for other purposes.
+
+```lua
+-- Creates a wrapper at the specified position, with the specified texture.
+-- Returns the wrapper id.
+gfx.blockwraps.wrap(position: vec3, texture: str) --> int
+
+-- Removes the wrapper, if it exists.
+gfx.blockwraps.unwrap(id: int)
+
+-- Changes the position of the wrapper, if it exists.
+gfx.blockwraps.set_pos(id: int, position: vec3)
+
+-- Changes the texture of the wrapper, if it exists.
+gfx.blockwraps.set_texture(id: int, texture: str)
+```
+
+Wrappers are not automatically removed without calling `unwrap`.

+# *network* library
+
+A library for working with the network.
+
+## HTTP requests
+
+```lua
+-- Performs a GET request to the specified URL.
+-- After receiving the response, passes the text to the callback function.
+network.get(url: str, callback: function(str))
+
+-- Example:
+network.get("https://api.github.com/repos/MihailRis/VoxelEngine-Cpp/releases/latest", function (s)
+    print(json.parse(s).name) -- will output the name of the latest engine release
+end)
+
+-- A variant for binary files, with a byte array instead of a string in the response.
+network.get_binary(url: str, callback: function(table|ByteArray))
+```
+
+## TCP Connections
+
+```lua
+network.tcp_connect(
+    -- Address
+    address: str,
+    -- Port
+    port: int,
+    -- Function called upon successful connection
+    -- Sending will not work before connection
+    -- Socket is passed as the only argument
+    callback: function(Socket)
+) --> Socket
+```
+
+Initiates TCP connection.
+
+The Socket class has the following methods:
+
+```lua
+-- Sends a byte array
+socket:send(table|ByteArray)
+
+-- Reads the received data
+socket:recv(
+    -- Maximum size of the byte array to read
+    length: int,
+    -- Use table instead of Bytearray
+    [optional] usetable: bool=false
+) -> nil|table|Bytearray
+-- Returns nil on error (socket is closed or does not exist).
+-- If there is no data yet, returns an empty byte array.
+
+-- Closes the connection
+socket:close()
+
+-- Checks that the socket exists and is not closed.
+socket:is_alive() --> bool
+
+-- Checks if the connection is present (using socket:send(...) is available).
+socket:is_connected() --> bool
+```
+
+```lua
+-- Opens a TCP server.
+network.tcp_open(
+    -- Port
+    port: int,
+    -- Function called when connecting
+    -- The socket of the connected client is passed as the only argument
+    callback: function(Socket)
+) --> ServerSocket
+```
+
+The SocketServer class has the following methods:
+
+```lua
+-- Closes the server, breaking connections with clients.
+server:close()
+
+-- Checks if the TCP server exists and is open.
+server:is_open() --> bool
+```
+
+## Analytics
+
+```lua
+-- Returns the approximate amount of data sent (including connections to localhost)
+-- in bytes.
+network.get_total_upload() --> int
+-- Returns the approximate amount of data received (including connections to localhost)
+-- in bytes.
+network.get_total_download() --> int
