# ...a word of warning follows, not copy-pasted...
Aside from the nil in the config snippet which is easy to catch (but should still be fixed), I had a slight WTF actually pointing my web app to the generated self-signed certificates. They rest comfortably in my $UMBRELLA_ROOT/priv/cert/ directory and me copy-pasting the above snippet in apps/myapp_web/config/dev.exs is looking for them in $UMBRELLA_ROOT/_build/dev/lib/myapp_web/priv/cert/selfsigned_key.pem. OK, I just move them to apps/lib/myapp_web/priv/certs/ and recompile. The local SSL listener works.
The generator should probably be umbrella-aware when offering help. It was easy to fix the error but I imagine it would catch off-guard somebody who is in a rush.
