+  <Overview>Agate is a server for the Gemini network protocol, built with the Rust programming language. Agate has very few features, and can only serve static files. It uses async I/O, and should be quite efficient even when running on low-end hardware and serving many concurrent requests.</Overview>

+  <Requires>To get your server going you should:&#xD;
+- Mount your gemini content under /gmi (make a directory for each hostname if you specify more than one later)&#xD;
+- Mount your certificates directory under /certs (if this is empty then new ones will be generated)&#xD;
+- Change the Post Arguments to include your hostname(s) eg: `--hostname example.org`&#xD;
+  - Note: If you specify more than one hostname then your contents directory must have one directory for each&#xD;
+&#xD;
+There is more configuration information in the Github README: https://github.com/mbrubeck/agate . Add any additional config to the "Post Arguments" below.</Requires>
