 You can also run:
 
 ```bash
-git node release -S --prepare --security=../vulnerabilities.json --filterLabel vX.x
+git node release -S --prepare --security=../security-release
 ```
 
+The `--security` flag takes the path to your clone of the `security-release`
+repository (or directly to a `vulnerabilities.json` file). The reports and
+dependency updates to cherry-pick are selected automatically from each entry's
+`affectedVersions` mapping for the release line you are on, and the matching
+`CVE-ID` trailers are added from the same file.
+
 Example:
 
 ```bash
 git checkout v20.x
-git node release -S --prepare --security=../vulnerabilities.json --filterLabel v20.x
+git node release -S --prepare --security=../security-release
 ```
 
 to automate the remaining steps until step 6 or you can perform it manually
 following the below steps. For semver-minors, you can pass the new version
 explicitly with `--newVersion` arg:
 
 ```bash
-git node release -S --prepare --security=../vulnerabilities.json --filterLabel v20.x --newVersion 20.20.0
+git node release -S --prepare --security=../security-release --newVersion 20.20.0
 ```
