+## Jenkins CI notes
+- The repo includes a declarative Jenkinsfile that builds on the `mcr.microsoft.com/dotnet/sdk:9.0` container image and expects Jenkins parameters for `GIT_REPO_URL`, `GIT_CREDENTIALS_ID`, `SONARQUBE_SERVER`, and `SONAR_TOKEN_ID`. Create the credentials in **Manage Jenkins › Credentials** before running the job.
+- Update the Sonar project key or organization by editing `SONAR_PROJECT_KEY` / `SONAR_ORG` in the Jenkins parameter defaults or overriding them per-run; the pipeline passes these values to `dotnet-sonarscanner`.
+- The pipeline publishes unit-test results, OpenCover XML, and HTML coverage reports; open the “Code Coverage” HTML report in the Jenkins build sidebar or download the archived artifacts `artifacts/AS400API-<build>-<commit>/reports/coverage-html/index.html`.
+- SCA results (`security-reports/nuget-vulnerabilities.txt` and optional Dependency-Check HTML) and application logs from `Logs/` are archived automatically so you can review findings without re-running the build.
+
 ## SonarQube analysis
 - Install or provision a SonarQube/SonarCloud server and generate a project token.
 - Set environment variables (`SONAR_HOST_URL`, `SONAR_TOKEN`, optionally `SONAR_PROJECT_KEY`, `SONAR_PROJECT_NAME`; defaults are `as400api` / `AS400API`, plus `SONAR_ORGANIZATION` for SonarCloud).
