+Verify digital signatures
+-------------------------
+
+First you need to install GPG or another PGP implementation.
+On most Linux distributions it's installed by default because package managers use it to verify package signatures.
+On other systems you may need to find and install the package.
+
+You nee to import the key.
+
+``gpg --import maintainers.key``
+
+| get the key from here: https://pgp.mit.edu/pks/lookup?op=vindex&search=0xFD220285A0FE6D7E
+| or alternatively, you can import it by hand:
