-* __Temporary upper bounds__ Most common technique, just prevent a new version of a library from being included immediately
-* __Skipping tests and benchmarks__ If the upper bound is only in a test suite or benchmark, you can add the relevant package to skipped-tests or skipped-benchmarks. For example, if conduit had an upper bound on criterion for a benchmark, you could added conduit as a skipped benchmark.
-* __Excluding packages__ In an extreme case of a non-responsive maintainer, you can remove the package entirely from Stackage. We try to avoid that whenever possible
+### Temporary upper bounds
+
+Most common technique, just prevent a new version of a library from
+being included immediately. This also applies to when only benchmarks
+and tests are affected.
+
+* Copy the stackage-curator output and create a new issue, see e.g
+https://github.com/fpco/stackage/issues/2108
+
+* Add a new entry under the "stackage upper bounds" section of `build-constraints.yaml`. For the above example it would be
+
+```yaml
+    "Stackage upper bounds":
+        # https://github.com/fpco/stackage/issues/2108
+        - pipes < 4.3.0
+```
+
+* Commit (message e.g. "Upper bound for #2108")
+* Optionally: Verify with `stackage-curator check` locally
+* Push
+* Verify that everything works on the build server (you can restart the build or wait for it to to run again)
+
+Sometimes releases for different packages are tightly coupled. Then it
+can make sense to combine them into one issue, as in
+https://github.com/fpco/stackage/issues/2143.
+
+If a dependency that is not explicitly in stackage is causing test or
+benchmark failures you can skip or expect them to fail (see "Skipping
+tests and benchmarks" and "Expecting test/benchmark/haddock
+failures"). Bonus points for reporting this upstream to that packages'
+maintainer.
+
+### Lifting upper bounds
+
+You can try this when you notice that a package has been updated. You
+can also periodically try to lift bounds (I think it's good to do this
+at the start of your week /@bergmark)
+
+If not all packages have been updated check if any of them are missing
+from the original issue and if so add a new comment mentioning them. A
+new package may appear if its dependencies were part of this issue but
+have been updated since the last time we checked. We want to give
+these new packages ample time to be upgraded.
+
+If stackage-curator is happy commit the change ("Remove upper bounds
+and close #X"). After doing this the next nightly build may fail
+because some packages didn't have an upper bound in place, but
+compilation failed. In this case revert the previous commit so any
+disabled packages are enabled again, re-open the issue, and add a new
+comment with the failing packages. This is to give all maintainers
+enough time to upgrade for this case as well.
+
+### Amending upper bounds
+
+With the `pipes` example above there was later a new release of
+`pipes-safe` that required the **newer** version of `pipes`. You can
+add that package to the same upper bounds section,
+(e.g. https://github.com/fpco/stackage/commit/6429b1eb14db3f2a0779813ef2927085fa4ad673)
+as we want to lift them simultaneously.
+
+### Skipping tests and benchmarks
+
+Sometimes tests and benchmark dependencies are forgotten or not cared
+for. To disable compilation for them add them to `skipped-tests` or
+`skipped-benchmarks`. If a package is added to these sections they
+won't be compiled, and their dependencies won't be taken into account.
+
+There are sub sections under these headers that is used to group types
+of failures together, and also to document what type of failures
+exist.
+
+### Expecting test/benchmark/haddock failures
+
+The difference from the `skipped` sections is that items listed here
+are compiled and their dependencies are taken into account. These
+sections also have sub sections with groups and descriptions.
+
+One big category of test suites in this section are those requiring
+running services. We don't want to run those, but we do want to check
+dependencies and compile them.
+
+If there are no version bounds that would fix the issue or if you
+can't figure it out, file it
+(e.g. https://github.com/fpco/stackage/issues/2133) to ask the
+maintainer for help.
+
+### Waiting for new releases
+
+Sometimes there is a failure reported on a (now possibly closed) issue
+on an external tracker. If an issue gets resolved but there is no
+hackage release yet we'd like to get notified when it's uploaded.
+
+Add the package with its current version to the
+`tell-me-when-its-released` section. This will cause the build to stop
+when the new version is out.
+
+### Excluding packages
+
+In an extreme case of a non-responsive maintainer, you can remove the
+package entirely from Stackage. We try to avoid that whenever
+possible.
+
+This typically happens when we move to a new major GHC release or when
+there are only a few packages waiting for updates on an upper bounds
+issue.
+
+Comment out the offending packages from the "packages" section and add
+a comment saying why it was disabled:
+
+```
+        # - swagger # bounds: aeson 1.0
+```
+
+If this causes reverse dependencies to be disabled we should notify
+the maintainers of those packages.
+
 
 ## Updating the content of the Docker image used for building

 Additional (non-Haskell) system libraries or tools should be added to `stackage/debian-bootstrap.sh`.

+## Local curator setup
+
+We do not run the full stackage build locally as that might take too
+much time. However, some steps on the other hand are much faster to do
+yourself, e.g. verifying constraints without building anything.
+
+To get started, install `stackage-curator` via Git, or [the Linux binary]:
+
+```
+$ git clone git@github.com:fpco/stackage-curator.git
+$ cd stackage-curator && stack install
+```
+
+It is a good idea to upgrade `stackage-curator` at the start of your week.
+Then, clone the stackage repo, get the latest packages and run dependency
+resolution:
+
+```
+$ git clone git@github.com:fpco/stackage.git
+$ stack update && stackage-curator check
+```
+
+This can be used to make sure all version bounds are in place, including for
+test suites and benchmarks, to check whether bounds can be lifted, and to get
+[tell-me-when-its-released] notifications.
+
+`stackage-curator` does not build anything, so you wont see any compilation
+errors for builds, tests and benchmarks.
+
+[the Linux binary]: https://s3.amazonaws.com/stackage-travis/stackage-curator/stackage-curator.bz2
+[tell-me-when-its-released]: https://github.com/fpco/stackage/blob/master/CURATORS.md#waiting-for-new-releases
