+# 2. Development
+
+Some tests cannot be run in CI becasue they test system specifics that
+simply do not exist in a CI environment. An example is the `isatty` function
+Which cannot be set to return a truthy value in CI.
+
+The tests concerned are all labelled with `#manual`. And in CI they will
+be skipped because `--exclude-tags=manual` is being passed to the
+`busted` command line.
+
+Hence if tests like this are being added, then please ensure the tests
+pass locally, and do not rely on CI only.
