+# Generating SSL certificates
+
+Typical usage:
+
+```shell
+make FILE=client
+make FILE=server
+```
+
+Will generate CA certificate and signed client and server certificates.
+
+More "low-level" usage:
+
+```shell
+make generate-ca-certificate
+make generate-private-key FILE=client 
+make sign FILE=client
+```
+
+# Connecting to a server
+
+First generate *client* and *server* certificates. Then start a server with it's cert and make ca.crt a trusted certification authority.
+
+After that you can:
+
+```shell
+./connect.sh client localhost:8600 < file_with_a_data_to_be_sent.dat
+```
