+Frequently-Asked Questions (FAQ)
+================================
+
+How do I update my changes?
+---------------------------
+
+Often it is necessary to update your patch set before it is merged. Refer to the
+`Gerrit Upload Patch Set documentation`_ on how to do so.
+
+If you need to modify an existing patch set with multiple commits, refer to the
+`Gerrit Replace Changes documentation`_.
+
+How long will my changes take to merge into ``integration``?
+------------------------------------------------------------
+
+This can vary a lot, depending on:
+
+* How important the patch set is considered by the TF maintainers. Where
+ possible, you should indicate the required timescales for merging the patch
+ set and the impact of any delay. Feel free to add a comment to your patch set
+ to get an estimate of when it will be merged.
+
+* The quality of the patch set. Patches are likely to be merged more quickly if
+ they follow the coding guidelines, have already had some code review, and have
+ been appropriately tested.
+
+* The impact of the patch set. For example, a patch that changes a key generic
+ API is likely to receive much greater scrutiny than a local change to a
+ specific platform port.
+
+* How much opportunity for external review is required. For example, the TF
+ maintainers may not wait for external review comments to merge trivial
+ bug-fixes but may wait up to a week to merge major changes, or ones requiring
+ feedback from specific parties.
+
+* How many other patch sets are waiting to be integrated and the risk of
+ conflict between the topics.
+
+* If there is a code freeze in place in preparation for the release. Please
+ refer the :ref:`Release Processes` document for more details.
+
+* The workload of the TF maintainers.
+
+How long will it take for my changes to go from ``integration`` to ``master``?
+------------------------------------------------------------------------------
+
+This depends on how many concurrent patches are being processed at the same
+time. In simple cases where all potential regressions have already been tested,
+the delay will be less than 1 day. If the TF maintainers are trying to merge
+several things over the course of a few days, it might take up to a week.
+Typically, it will be 1-2 days.
+
+The worst case is if the TF maintainers are trying to make a release while also
+receiving patches that will not be merged into the release. In this case, the
+patches will be merged onto ``integration``, which will temporarily diverge from
+the release branch. The ``integration`` branch will be rebased onto ``master``
+after the release, and then ``master`` will be fast-forwarded to ``integration``
+1-2 days later. This whole process could take up 4 weeks. Please refer to the
+:ref:`Release Processes` document for code freeze dates. The TF maintainers
+will inform the patch owner if this is going to happen.
+
+It is OK to create a patch based on commits that are only available in
+``integration`` or another patch set, rather than ``master``. There is a risk
+that the dependency commits will change (for example due to patch set rework or
+integration problems). If this happens, the dependent patch will need reworking.
+
+What are these strange comments in my changes?
+----------------------------------------------
+
+All the comments from ``ci-bot-user`` are associated with Continuous Integration
+infrastructure. The links published on the comment are not currently accessible,
+but would be after the CI has been transitioned to `trustedfirmware.org`_.
