+### HTTPS support
+
+This images are default configured with HTTPS enabled, and use a default certificate stored in defaults/freeworldKeystore. You should use your own certificated. In order to do it, you can proceed as follow.
+
+#### Self-signed certificate
+
+A self-signed certificate will provide encrypted communications with your YaCy server, but browsers will still complain about an invalid security certificate with the error "SEC_ERROR_UNKNOWN_ISSUER". If it is sufficient for you, you can add permanently add exception to your browser. 
+
+This kind of certificate can be generated and added to your YaCy Docker container with the following :
+
+	keytool -keystore /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacykeystore -genkey -keyalg RSA -alias yacycert
+	
+Then edit YaCy config file. For example with the nano text editor :
+
+	nano /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacy.conf
+
+And configure the keyStoreXXXX properties accordingly :
+
+	keyStore=/opt/yacy_search_server/DATA/SETTINGS/yacykeystore
+	keyStorePassword=yourpassword
+	
+#### Import an existing certificate:
+
+Importing a certificated validated by a certification authority (CA) will ensure you full HTTPS support with no security errors when accessing your YaCy peer. You can import an existing certificate in pkcs12 format.
+
+First copy it to the YaCy Docker container volume :
+
+	cp [yourStore].pkcs12 /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/[yourStore].pkcs12
+	
+Then edit YaCy config file. For example with the nano text editor :
+
+	nano /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacy.conf
+
+And configure the pkcs12XXX properties accordingly :
+
+	pkcs12ImportFile=/opt/yacy_search_server/DATA/SETTINGS/[yourStore].pkcs12
