+>Start the a1-interface container without specifing external certificates:<br>
+```docker run --rm -it -p 3905:3905 -p 3906:3906 mrstub```
+
+It will listen to http 3905 port and https 3906 port(using default certificates) at the same time.
+
+This certificates/key can be overriden by mounting a volume when using "docker run" or "docker-compose"
+In 'docker run', use field:<br>
+>```-v "$PWD/certificate:/usr/src/app/cert"```<br>
+
+eg:<br>
+>```docker run --rm -it -p 3905:3905 -p 3906:3906 -v "/PATH_TO_CERT/cert:/usr/src/app/cert" mrstub```<br>
