-- Scan an image:
+- Scan a Docker image for vulnerabilities and exposed secrets:
 
 `trivy image {{image:tag}}`
 
+- Scan a Docker image filtering the output by severity:
+
+`trivy image --severity {{HIGH,CRITICAL}} {{alpine:3.15}}`
+
+- Scan a Docker image ignoring any unfixed/unpatched vulnerabilities:
+
+`trivy image --ignore-unfixed {{alpine:3.15}}`
+
 - Scan the filesystem for vulnerabilities and misconfigurations:
 
 `trivy fs --security-checks {{vuln,config}} {{path/to/project_directory}}`
 
-- Scan a directory for misconfigurations:
+- Scan a IaC (Terraform, CloudFormation, ARM, Helm and Dockerfile) directory for misconfigurations:
 
 `trivy config {{path/to/iac_directory}}`
 
+- Scan a local or remote Git repository for vulnerabilities:
+
+`trivy repo {{path/to/local_repository_directory|remote_repository_URL}}`
+
+- Scan a Git repository up to a specific commit hash:
+
+`trivy repo --commit {{commit_hash}} {{repository}}`
+
 - Generate output with a SARIF template:
 
 `trivy image --format {{template}} --template {{"@sarif.tpl"}} -o {{path/to/report.sarif}} {{image:tag}}`
