Readers could have questions like this:

• I found a typo. How can I help to fix it?
• I have a proposal for the next version of the spec. How can I start a discussion?
• I have an idea but I am not sure if this was already discussed. Where can I find previous discussions?
• I have an idea but I am not sure if it should open an issue with datacite, schema, or schema-docs
• Are there formal requirements for proposals?
• Is participation even wanted?

All this could be answered in a paragraph somewhere in the introduction.
