+## Running gui-tests in docker
+
+The easiest way to run the gui-tests in a stable environment setup as they
+expect is by spinning up a temporary web service with the correct data in
+docker.
+
+This is supported by the `in-docker` script. It has three phases that can be
+run, to allow quicker feedback when editing the gui-tests themselves.
+
+```console
+# initialize a temporary database and web service and builds some crates in it
+> gui-tests/in-docker init
+...
+ ✔ Container docsrs-db-1             Healthy
+ ✔ Container docsrs-s3-1             Healthy
+ ✔ Container docsrs-gui-tests-web-1  Healthy
+
+# while you have changes to make
+# do
+  # edit your tests
+  > vim gui-tests/basic.goml
+
+  # run the tests against the temporary web service
+  > gui-tests/in-docker run
+  ...
+  Running 2 docs.rs GUI (2 concurrently) ...
+  ..         (2/2)
+# done
+
+# tear down the temporary database and web service
+> gui-tests/in-docker cleanup
+...
+Removed `local/gui-tests` successfully.
+```
+
+Running with `all` or without an argument will run all steps in sequence,
+skipping the cleanup if it fails so you can inspect the failure. Useful if
+you've done some other changes and want to run the gui-tests but aren't
+expecting them to fail.
+
+If you are changing the web service or doc builder, take a look in the script at
+the steps that `init` takes, you can likely run just one of these steps manually
+within your edit-test loop rather than having to fully reinit the setup
+(remember to use `--build` to ensure docker-compose rebuilds the image from your
+updated source).
+
+```console
+# e.g. after editing the doc builder
+docker compose run --build --rm gui-tests-builder build crate sysinfo 0.23.4
+docker compose run --build --rm gui-tests-builder build crate sysinfo 0.23.5
+
+# or after editing the web service
+docker compose up --build --wait --wait-timeout 10 gui-tests-web
+```
+
+The web service is also bound onto `localhost:3001` so that you can manually
+inspect the pages if necessary.
