+# How to:
+# First, `make yourhost.cnf` which creates a openssl config file.
+# Then edit this file and fill in the details you want it to have,
+# and add or change hosts and components it should cover.
+# Then `make yourhost.key` to create your private key, you can
+# include keysize=number to change the size of the key.
+# Then you can either `make yourhost.csr` to generate a certificate
+# signing request that you can submit to a CA, or `make yourhost.crt`
+# to generate a self signed certificate.
