 ## Standards
 Anyone is free to review and comment on any [open pull requests](https://github.com/prebid/prebid-server-java/pulls).
 
-All pull requests must be reviewed and approved by at least one [core member](https://github.com/orgs/prebid/teams/core/members) before merge.
-
-Very small pull requests may be merged with just one review if they:
-
-1. Do not change the public API.
-2. Have low risk of bugs, in the opinion of the reviewer.
-3. Introduce no new features, or impact the code architecture.
-
-Larger pull requests must meet at least one of the following two additional requirements.
-
-1. Have a second approval from a core member
-2. Be open for 5 business days with no new changes requested.
+1. PRs that touch only adapters and modules can be approved by one reviewer before merge.
+2. PRs that touch PBS-core must be reviewed and approved by at least two 'core' reviewers before merge.
 
 ## Process
 
-New pull requests should be [assigned](https://help.github.com/articles/assigning-issues-and-pull-requests-to-other-github-users/) 
-to a core member for review within 3 business days of being opened.
-That person should either approve the changes or request changes within 4 business days of being assigned.
-If they're too busy, they should assign it to someone else who can review it within that timeframe.
+New pull requests must be [assigned](https://help.github.com/articles/assigning-issues-and-pull-requests-to-other-github-users/) 
+to a reviewer within 5 business days of being opened. That person must either approve the changes or request changes within 5 business days of being assigned.
+
+If a reviewer is too busy, they should re-assign it to someone else as soon as possible so that person has enough time to take over the review and still meet the 5-day goal. Please tag the new reviewer in the PR. If you don't know who to assign it to, use the #prebid-server-java-dev Slack channel to ask for help in re-assigning.
 
-If the changes are small, that member can merge the PR once the changes are complete. Otherwise, they should
-assign the pull request to another member for a second review.
+If a reviewer is going to be unavailable for more than a few days, they should update the notes column of the duty spreadsheet or drop a note about their availability into the Slack channel.
 
-The pull request can then be merged whenever the second reviewer approves, or if 5 business days pass with no farther
-changes requested by anybody, whichever comes first.
+After the review, if the PR touches PBS-core, it must be assigned to a second reviewer.

 Code reviews should focus on things which cannot be validated by machines.

 - Does the code use any global, mutable state? [Inject dependencies](https://en.wikipedia.org/wiki/Dependency_injection) instead!
 - Can the code be organized into smaller, more modular pieces?
 - Is there dead code which can be deleted? Or TODO comments which should be resolved?

+- Look for code used by other adapters. Encourage adapter submitter to utilize common code.
+- Specific bid adapter rules:
+    - The email contact must work and be a group, not an individual.
+    - Host endpoints cannot be fully dynamic. i.e. they can utilize "https://REGION.example.com", but not "https://HOST".
+    - They cannot _require_ a "region" parameter. Region may be an optional parameter, but must have a default.
+    - No direct use of HTTP is prohibited - *implement an existing Bidder interface that will do all the job*
+    - If the ORTB is just forwarded to the endpoint, use the generic adapter - *define the new adapter as the alias of the generic adapter*
