Jack,
The requirements to amend should be found within the documents themselves. Typically it's a high percentage of owners (usually 2/3 or more).
The typical procedure would be simple:
Publish the proposed amendment to the membership
Hold a general membership meeting
Take a vote
If the amendment passes, have it recorded and publish the adopted amendment to all members.
Of course, the draft amendment should likely be reviewed by an attorney for comments and suggestions
prior to proposing it to the membership. Otherwise you may adopt an amendment that might not be legally enforceable.
Here is a link to the davis-stirling site's webpage on amendments:

We actually formed a committee of homeowners (no board members) to review and propose changes to the governing docs.
Once the committee made a recommendation the Board reviewed it and made changes as they saw were needed.
The draft amendments were then sent to the membership for review and comment at an informational meeting on the topic.
The Board then made changes based on those comments.
The revised draft then went to the attorney for review and comment.
The Board made changes based on the attorney's comments and created the proposed amendment.
This proposed amendment then went to the membership along with the notice of a meeting to adopt.
The Board then hit the pavement and began knocking on doors encouraging members to attend or assign a proxy so the any vote could meet the requirements to amend outlined within the governing docs.
