Improve documentation please

[jsapede]

the tool seems extremely powerful but, as a non specialist neither in python nor in LLM/RAG, documention is quite opbscure and imcomplete.

for example :

• been struggling to setup ollama URL but even using env variables it always point to localhost.
• trying to run example and got error with leann.settings but explained nowher in the doc.

documentation merges leann CLI commands with some python prebuilt scripts without explanation
even installation process is obscure with so many options mixed with no eplanation

would it be possible to have a clear CLI reference page ans how to articulate it through mcp ?
