A Gerrit how-to for those moments our brains fail us with the lovely error message.
 * See also: Gerrit/Tutorial.

Creating a patchset

 * 1) Ensure the repository is set up with git review -s (remember: s for setup). Only required if there's not a .gitreview file in the repository
 * 2) Prepare the repository:
 * 3) Pull the latest changes from the repository with git pull origin master
 * 4) Create a branch for your changes with git checkout -b BRANCHNAME-GOES-HERE origin/master . Remember to name it appropriately, such as T2001/SHORT-DESCRIPTION
 * 5) Make your changes
 * 6) Prepare to commit:
 * 7) Check if the commit meets the Pre-commit checklist
 * 8) Write the commit message, for the guidelines see Gerrit/Commit message guidelines
 * 9) Commit with git commit . Don't use the -m flag because it restricts you to only the commit summary
 * 10) Prepare for pushing:
 * 11) Update your local repository with git pull --rebase origin master . It isn't strictly mandatory, but on repositories with a high update rate, it can prevent trouble
 * 12) Push your changes with git review -R . If you did not use the step above, omit -R as it tells git-review not to perform a rebase
 * 13) (Optional, but recommended) Add some reviewers. See Developers/Maintainers
 * 14) After the patch is merged or abandoned, switch back to master with git checkout master and remove the branch with git branch -d BRANCHNAME-GOES-HERE

Existing

 * Your current branch is not the one from the patchset but does exist locally


 * 1) Run git checkout and follow the steps below:
 * Your current branch is the one of the patchset.


 * 1) Make your changes (see above)
 * 2) Commit with git commit --amend
 * 3) * Use --all only when you want all changes, regardless if they have been staged, to be amended.
 * 4) Run git review -R to push the changes to Gerrit

Other

 * You don't have the patch yet.


 * 1) Get the patch with git review -d GERRIT-CHANGE-NUMBER-GOES-HERE . Beware that this does destroy your local changes, so stash or/and commit first.
 * 2) Follow the steps above.

Creating a new branch
So far, I only know of one way to do this, using Gerrit's web interface:
 * 1) Find your project's Gerrit page and append ,branches : https://gerrit.wikimedia.org/r/#/admin/projects/PROJECTNAME/SUBPROJECTNAME,branches
 * 2) Create a new branch by specifying its name and the initial revision

UI
See https://review.gerrithub.io/Documentation/user-review-ui.html for an extensive guide that covers each part of the review interface.
