+### schema(output_type)
+
+The `schema()` procedure generates the graph database schema in a **prompt-ready** or **raw** format. The prompt-ready format is optimized to describe the database schema in words best recognized by large language models (LLMs). The raw format offers all the necessary information about the graph schema in a format that can be customized for later use with LLMs.
+
+#### Input:
+
+* `output_type: str (default='prompt_ready')` ➡ By default, the graph schema will include additional context and it will be prompt-ready. If set to 'raw', it will produce a simpler version that can be adjusted for the prompt.
+
+#### Output:
+
+* `schema: mgp.Any` ➡ `str` containing prompt-ready graph schema description in a format suitable for large language models (LLMs), or `mgp.List` containing information on graph schema in raw format which can customized for LLMs. 
+
+#### Usage:
+Get **prompt-ready graph schema**:
+```cypher
+CALL llm_util.schema() YIELD schema RETURN schema;
+```
+or
+```cypher
+CALL llm_util.schema('prompt_ready') YIELD schema RETURN schema;
+```
+
+Get **raw graph schema**:
+```cypher
+CALL llm_util.schema('raw') YIELD schema RETURN schema;
+```
+
+:::note
+The `output_type` is case-insensitive.
