 # gmnisrv
 
-WIP, come back later
+gmnisrv is a simple [Gemini](https://gemini.circumlunar.space) protocol server.
+
+## Installation
+
+```
+$ mkdir build
+$ cd build
+$ ../configure --prefix=/usr
+$ make
+# make install
+```
+
+## Configuration
+
+By default it reads from `/etc/gmnisrv.ini`, but this can be changed by passing
+the `-C` flag to the `gmnisrv` daemon. A sample config.ini is provided at
+`/usr/share/gmnisrv/gmnisrv.ini`:
+
+```
+# Space-separated list of hosts
+listen=0.0.0.0:1965 [::]:1965
+
+[:tls]
+# Path to store certificates on disk
+store=/var/lib/gemini/certs
+
+# Optional details for new certificates
+organization=gmnisrv user
+
+[localhost]
+root=/var/www
+```
+
+For full details on gmnisrv configuration, consult the *gmnisrv*(5) manual page.
+
+## Usage
+
+See *gmnisrv*(1).

+# NAME
+
+gmnisrv - serve clients over the gemini protocol

+# SYNPOSIS
+
+*gmnisrv* [-C _path_]
+
+# DESCRIPTION
+
+*gmnisrv* is a daemon which serves network clients over the gemini protocol. It
+requires a config file; by default this shall be read from /etc/gmnisrv.ini
+unless the installation was configured with a different SYSCONFDIR or the user
+provides the -C flag.
+
+# OPTIONS
+
+*-C* _path_
+	Specifies an alternate path to read the config file from.

+
+# NAME
+
+*gmnisrv.ini* - configuration file for *gmnisrv*(1)
+
+# SYNTAX
+
+*gmnisrv.ini* is an INI file. Each line is either a key/value pair, or a section
+heading. Key/value pairs are specified as key=value, and sections as [section].
+
+# CONFIGURATION KEYS
+
+The meaning of the key depends on the section. Anonymous keys (prior to the
+first [section] directive) are used to specify parameters for the daemon itself.
+Sections whose name is prefixed with ":", e.g. [:tls], are sub-categories of
+the daemon configuration. Otherwise, section names refer to the hostnames of
+domains serviced by the *gmnisrv* daemon.
+
+## ANONYMOUS KEYS
+
+*listen*
+	A space-separated list of addresses that the daemon shall bind to. Each
+	address shall take the format *address*:*port*. If :*port* is omitted,
+	1965 (the default Gemini port) is presumed. To specify an IPv6 address,
+	enclose it in *[]*, e.g. *[::]*.
+
+
+## TLS KEYS
+
+The following keys are accepted under the *[:tls]* section:
+
+*store*
+	Path to the certificate store on disk. This should be a persistent
+	directory writable by the daemon. The daemon manages its own
+	certificates - no user intervention is required, except in the case of
+	moving the daemon to another host, in which case the certificate store
+	must be copied to the new host.
+
+*organization*
+	An optional key used during certificate generation. Fill this in with
+	the name of the organization responsible for the host and it will be
+	filled in as the X.509 /O name.
+
+## HOST KEYS
+
+Hosts that *gmnisrv* is to serve shall be defined in *gmnisrv.ini* by
+introducing config sections named after each host to provide service for. The
+following keys apply:
+
+*root*
+	Configures the path on disk from which files shall be served for this
+	host.
+
+*index*
+	Configures the name of the index file which shall be served in the event
+	that a request for this host does not include the filename part.
+	Defaults to "index.gmi".
+
+*autoindex*
+	"on" to enable the auto-index feature, which presents clients with a
+	list of files in the requested directory when an index file cannot be
+	found. Off by default.
