Added a few notes and tips.

First commit here, am I doing this right?
This is fine, but please use the standard content block that's translated into all languages:

```
      - type: say
        content:
          - lang: en
            str: 'Contains dirty edits: Do not clean. "Dirty" edits are intentional and required for the mod to function.'
          - lang: ru
            str: '''Грязные'' правки: Не очищать. ''Грязные'' правки оставлены специально и требуются для функционирования мода.'
          - lang: es
            str: 'Contiene ediciones sucia: Do not clean. "Dirty" edits are intentional and required for the mod to function.'
```
