+## Component
+
+Primarily, this command is used to generate lists of components that are included in a CycloneDX SBOM.
+
+### Component `list` command
+
+This command is used to extract, filter and list CycloneDX BOM `Component` data.
+
+#### Component list supported formats
+
+This command supports the `--format` flag with any of the following values:
+
+- `txt` (default), `csv`, `md`
+
+#### Component list flags
+
+##### Component list `--summary` flag
+
+Use the `--summary` flag on the `component list` command to produce a summary report with reduced column information.
+
+#### Component list examples
+
+##### Example: `component list`
+
+This example shows the component list with all column information display. Since CycloneDX component data can be very extensive, many columns simply indicate the component `has` more data available which can be extracted using the `query` command if needed.
+
+```bash
+./sbom-utility component list -i test/cyclonedx/1.6/specification/valid-bom-1.6.json -q
+```
+

+##### Example: `component list` summary in markdown format
+
+The same BOM component information as in the previous example; however, with output produced in markdown table format and using the summary flag to reduce the number of columns.
+
+```bash
+./sbom-utility component list -i test/cyclonedx/1.6/specification/valid-bom-1.6.json --summary --format=md -q
+```
