For each config-projects, add a peer faq file like

```
src/config-projects/chatopera.faqs.yml
```

Which would be configured as FAQs for ```src/config-projects/chatopera.ts``` .


```src/config-projects/chatopera.faqs.yml``` would be in a format like

```
- chatopera/*
- {{Question1}}
- categories: x / y / z
- answers:
- {{A1}}

- {{E3}}
...
```

Everytime OSSChat restart or start, reload these FAQs and import into Chatopera BOT, updates, deleltion, creation should be under considered.
