+## *json* library
+
+The library contains functions for serializing and deserializing tables:
+
+```python
+json.tostring(object: table, human_readable: bool=false) -> str
+```
+
+Serializes an object into a JSON string. If the second parameter is **true**, multi-line human-readable formatting will be used, rather than the compact format used by default.
+
+```python
+json.parse(code: str) -> table
+```
+
+Parses a JSON string into a table.
+
+## *toml* library
+
+The library contains functions for serializing and deserializing tables:
+
+```python
+toml.tostring(object: table) -> str
+```
+
+Serializes an object into a TOML string.
+
+```python
+toml.parse(code: str) -> table
+```
+
+Parses a TOML string into a table.
+
+## *bjson* library
+
+The library contains functions for working with the binary data exchange format [vcbjson](../../specs/binary_json_spec.md).
+
+```lua
+-- Encodes a table into a byte array
+bjson.tobytes(
+    -- encoded table
