fix for self signed ssl to work in browsers

roles/sslselfsigned/DESIGN.md

+# Design Description for SSL Self Signed
+
+This generates a Certificate Authority (CA) and then a signing request (CSR), which results in the certificate for this server after signing it with our CA.
+
+The CA cert is placed in the secret folder, you can install it eg. in Arch like this:
+
+    sudo trust anchor --store secret/DOMAIN/sovereign-self-signed-cert/DOMAIN/etc/letsencrypt/live/DOMAIN/chain.pem
+
+It will then automatically be picked up by browsers like Firefox and Chrome.
