#Using client certificate

Castor expects your certificates to be placed in your home directory and named after the gemini capsule domain. For example to water your plant on gemini://astrobotany.mozz.us/plant you will need to have astrobotany.mozz.us.crt and astrobotany.mozz.us.key available in your home.

#Mailing list

If you have questions, feature requests, bugs or you just want to keep up to date with Castor you can send a message to the mailing list
