+```bash
+pip install git+https://github.com/ai-cfia/llamaindex-db.git@main#subdirectory=ailab-llama-search
+```
 
-## Configuration
+## Usage
 
-TODO
+```python
+from ailab_llama_search import create_index_object, search
 
-## Usage
+# adapt these parameters to your needs

 ## Exceptions
 
-TODO
+- `AilabLlamaSearchError`: Triggered if the search query string is empty or
+  `None`.
 
 ## Functions
 
-TODO
+- `search`: Executes search queries against a LlamaIndex `VectorStoreIndex`.
+- `create_index_object`: Generates a `VectorStoreIndex` object needed to use the
+  `search` function.
+- `transform`: Modifies search result data based on predefined mappings.
