+# Coverity Testing
+#
+# Coverity (https://scan.coverity.com) is a static code analysis software that analyzes sourcecode
+# and spots problems like null pointer dereferences or incorrect expressions. To execute Coverity on
+# your release, the release needs to be pushed to the branch coverity_scan. After pushing the release
+# to the branch, a GitHub action (https://github.com/timescale/timescaledb/blob/main/.github/workflows/coverity.yaml)
+# is triggered that starts the code analysis.
+
+# You can see the result of the Coverity scan under the URL (https://scan.coverity.com/projects/timescale-timescaledb?tab=overview).
+# A few minutes after you have pushed your changes to the coverity_scan branch, you should see that the
+# check of commit has been started. When the check is done, there should be no new errors reported (0 Newly detected).
+#
+# Note: Some rate limits (https://scan.coverity.com/faq#frequency) apply to the Coverity service. So,
+# don't push your branch too often to this service.
