+# Dependency Management
+This document describes the current status of our dependency management and dependency assessment.
+
+# Never ignore errors and warnings
+If `ỳarn` issues a `warning` or `error`then act on it and do an assessment.
+Our CI/CD pipeline will check if there are warnings or errors that are new and not yet assessed.
+
+# Assessment of warnings and errors
+If you spot yarn errors and warnings then fix it. If you think it is safe to ignore them, then add the warning or error 
+message to our [ignore list](./yarn_issues_assessed.txt) and put a comment line above it to inform other developers 
+why it is safe to ignore this message.
