+### Generate TLS assets
+
+Running Dex with HTTPS enabled requires a valid SSL certificate, and the API server needs to trust the certificate of the signing CA using the `--oidc-ca-file` flag.
+
+For our example use case, the TLS assets can be created using the following command:
+
+```
+$ ./examples/k8s/gencert.sh 
+```
+
+This will generate several files under the `ssl` directory, the important ones being `cert.pem` ,`key.pem` and `ca.pem`. The generated SSL certificate is for 'dex.example.com', although you could change this by editing `gencert.sh` if required.

+Dex operates like most other OAuth2 providers. Users are redirected from a client app to dex to login. Dex ships with an example client app (built with the `make examples` command), for testing and demos.
 
 By default, the example client is configured with the same OAuth2 credentials defined in `examples/config-dev.yaml` to talk to dex. Running the example app will cause it to query dex's [discovery endpoint][oidc-discovery] and determine the OAuth2 endpoints.
