+## Érico's gemini place
+
+### How to use
+
+Create certs in `certs/` using with `generate.sh`, which requires
+[x509cert(1)](https://x509cert.mforney.org/x509cert.1.html).
+
+Copy [lc19](https://sr.ht/~thededem/lc19/) executable to directory, install
+[s6-networking](https://skarnet.org/software/s6-networking/), and run
+`host.sh`.
+
+#### void-docs
+
+If you want to use `void-docs.erico.dev` domain, it's necessary to generate
+certs with `N=2` and `CN=void-docs.erico.dev`. Files should be generated from a
+[void-docs](https://github.com/void-linux/void-docs) repository and copied
+here:
+
+```sh
+$ cp -r book/gemini/* /path/to/ericonr-gemini/gemini/void-docs.erico.dev/1965/
