To add any code documentation website as a loader, use the data_type as docs_site. Eg:

from embedchain import App

app = App()
app.add("", data_type="docs_site")
app.query("What is Embedchain?")
# Answer: Embedchain is a platform that utilizes various components, including paid/proprietary ones, to provide what is believed to be the best configuration available. It uses LLM (Language Model) providers such as OpenAI, Anthpropic, Vertex_AI, GPT4ALL, Azure_OpenAI, LLAMA2, JINA, Ollama, Together and COHERE. Embedchain allows users to import and utilize these LLM providers for their applications.'
