+#### Installing Trusted SSL Server Certificates
+If your GitLab CI server is using self-signed SSL certificates then you should make sure the GitLab CI server certificate is trusted on the GitLab server for them to be able to talk to each other.
+
+The default path image is configured to look for the trusted SSL certificates is at /home/git/data/certs/ca.crt, this can however be changed using the CA_CERTIFICATES_PATH configuration option.
+
+Copy the ca.crt file into the certs directory on the [datastore](#data-store). The ca.crt file should contain the root certificates of all the servers you want to trust. With respect to GitLab CI, this will be the contents of the gitlab_ci.crt file as described in the [README](https://github.com/sameersbn/docker-gitlab-ci/blob/master/README.md#ssl) of the [docker-gitlab-ci](https://github.com/sameersbn/docker-gitlab-ci) container.
+
+By default, our own server certificate [gitlab.crt](#generation-of-self-signed-certificates) is added to the trusted certificates list.
