 demonstration. Please ensure you know what your risk is to use the sample keys
 in your product, because they are completely public.
 
+If sample keys are used, the private IMA key is installed as /etc/keys/x509_ima.key.
+
+A typical signing command is as following:
+
+    # evmctl ima_sign --hashalgo sha256 --key /etc/keys/x509_ima.key --pass=<passowrd> /path/to/file
+or
+
+    # evmctl ima_sign --hashalgo sha256 --key /etc/keys/x509_ima.key --pass=<passowrd> -r /path/to/directory
+
+The following command can be used to verify a file's IMA signature with specified certificate:
+
+    # evmctl ima_verify --key /etc/keys/x509_ima.der /path/to/file
+
 ### RPM File Signing
 The payloads in a RPM are signed by the private key during the build, and each
 IMA signatures for the corresponding  payload file will be eventually written
