+## Shortr
+
+Single PHP URL Shorter
+
+Database and table needed, build on MariaDB / MySQL:
+
+	CREATE DATABASE IF NOT EXISTS `shortr` DEFAULT CHARACTER SET latin1 COLLATE latin1_swedish_ci;
+	USE `shortr`;
+
+	CREATE TABLE `urls` (
+	  `id` varchar(255) NOT NULL,
+	  `url` text DEFAULT NULL,
+	  `timestamp` timestamp NOT NULL DEFAULT current_timestamp(),
+	  `ip` varchar(255) DEFAULT NULL,
+	  `count` int(11) NOT NULL
+	) ENGINE=InnoDB DEFAULT CHARSET=latin1;
+
+
+Example OpenBSD httpd.conf
+
+	server "host.domain.tld" {
+		listen on $local_v4 port 80
+		tcp { nodelay, sack }
+		log style forwarded
+		root "/htdocs/host.domain.tld/shortr"
+		directory { index "index.php" }
+		location match "^/[%l%u%d]+$" {
+			request rewrite "/index.php?hash=%1"
+		}
+		location "/*.php*" {
+			fastcgi socket "/run/php-fpm.sock"
+		}
+	}
+
+Configuration file needs to be renamed to conf.php
+
+Configuration options:
+
+	define("SITE_TITLE", "NAME OF SITE");
+	define("BASE_URL", 'https://host.domain.tld/');
+	define("DB_HOST", 'localhost');
+	define("DB_USER", 'shortr');
+	define("DB_PASS", 'RandomStringOfChars');
+	define("DB_NAME", 'shortr');
+	define("DB_TABLE", 'urls');
