-#yaamp
+#yiimp - yaamp fork
+
+Required:
+
+	linux, mysql, php, memcached, a webserver (lighttpd or nginx recommended)
+
+
+Config for nginx:
+
+	location / {
+		try_files $uri @rewrite;
+	}
+
+	location @rewrite {
+		rewrite ^/(.*)$ /index.php?r=$1;
+	}
+
+	location ~ \.php$ {
+		fastcgi_pass unix:/var/run/php5-fpm.sock;
+		fastcgi_index index.php;
+		include fastcgi_params;
+	}
+
+
+If you use apache, it should be something like that (already set in web/.htaccess):
+
+	RewriteEngine on
+
+	RewriteCond %{REQUEST_FILENAME} !-f
+	RewriteRule ^(.*) index.php?r=$1 [QSA]
+
+
+If you use lighttpd, use the following config:
+
+	$HTTP["host"] =~ "yiimp.ccminer.org" {
+	        server.document-root = "/var/yaamp/web"
+	        url.rewrite-if-not-file = (
+			"^(.*)/([0-9]+)$" => "index.php?r=$1&id=$2",
+			"^(.*)\?(.*)" => "index.php?r=$1&$2",
+	                "^(.*)" => "index.php?r=$1",
+	                "." => "index.php"
+	        )
+
+		url.access-deny = ( "~", ".dat", ".log" )
+	}
+
+
+For the database, import the initial dump present in the sql/ folder
+
+Then, apply the migration scripts to be in sync with the current git, they are sorted by date of change.
+
+Your database need at least 2 users, one for the web site (php) and one for the stratum connections (password set in config/algo.conf).
+
+
+
+The recommended install folder for the stratum engine is /var/stratum. Copy all the .conf files, run.sh, the stratum binary and the blocknotify binary to this folder. 
+
+Some scripts are expecting the web folder to be /var/web. You can use directory symlinks...
+
+
+Add your exchange API public and secret keys in these two separated files:
+
+	/etc/yiimp/keys.php - fixed path in code
+	web/serverconfig.php - use sample as base...
+
+You can find sample config files in web/serverconfig.sample.php and web/keys.sample.php
+
+This web application includes some command line tools, add bin/ folder to your path and type "yiic" to list them, "yiic checkup" can help to test your initial setup.
+Future scripts and maybe the "cron" jobs will then use this yiic console interface.
+
+You need at least three backend shells (in screen) running these scripts:
+
+	web/main.sh
+	web/loop2.sh
+	web/block.sh
+
+Start one stratum per algo using the run.sh script with the algo as parameter. For example, for x11:
+
+	run.sh x11
+
+Edit each .conf file with proper values.
+
+Look at rc.local, it starts all three backend shells and all stratum processes. Copy it to the /etc folder so that all screen shells are started at boot up.
+
+All your coin's config files need to blocknotify their corresponding stratum using something like:
+
+	blocknotify=blocknotify yaamp.com:port coinid %s
+
+On the website, go to http://server.com/site/adminRights to login as admin. You have to change it to something different in the code (web/yaamp/modules/site/SiteController.php). A real admin login may be added later, but you can setup a password authentification with your web server, sample for lighttpd:
+
+	htpasswd -c /etc/yiimp/admin.htpasswd <adminuser>
+
+and in the lighttpd config file:
+
+	# Admin access
+	$HTTP["url"] =~ "^/site/adminRights" {
+	        auth.backend = "htpasswd"
+	        auth.backend.htpasswd.userfile = "/etc/yiimp/admin.htpasswd"
+	        auth.require = (
+	                "/" => (
+	                        "method" => "basic",
+	                        "realm" => "Yiimp Administration",
+	                        "require" => "valid-user"
+	                )
+	        )
+	}
+
+And finally remove the IP filter check in SiteController.php
+
+
+
+There are logs generated in the /var/stratum folder and /var/log/stratum/debug.log for the php log.
+
+More instructions coming as needed.
+
+
+There a lot of unused code in the php branch. Lot come from other projects I worked on and I've been lazy to clean it up before to integrate it to yaamp. It's mostly based on the Yii framework which implements a lightweight MVC.
