+### Application build and update
+
+For application deployment we are using faster [Mina](https://github.com/mina-deploy/mina) 
+instead of Capistrano.
+
+All deploy code locates at config/deploy.rb file.
+
+First add shortcuts to your local machine ssh config file, 
+
+```
+~/.ssh/config file:
+# staging
+Host registry-st
+  HostName YOUR-REGISTRY-STAGING-SERVER-IP
+  User registry
+
+# production
+Host registry
+  HostName YOUR-REGISTRY-SERVER-IP
+  User registry
+
+# staging
+Host eppweb-st
+  HostName YOUR-EPPWEB-STAGING-SERVER-IP
+  User registry
+
+# production
+Host eppweb
+  HostName YOUR-EPPWEB-SERVER-IP
+  User registry
+
+# staging
+Host whois-st
+  HostName YOUR-WHOIS-STAGING-SERVER-IP
+  User registry
+
+# production
+Host whois
+  HostName YOUR-WHOIS-SERVER-IP
+  User registry
+```
+
+Those shortcuts should be same as in config/deploy.rb script, 
+otherwise mina will not deploy.
+
+Mina help and all mina commands:
+
+    mina -h
+    mina -T
+
+Setup application directories for a new server:
+
+    mina setup     # staging
+    mina pr setup  # production 
+
+Deploy new code:
+
+    mina deploy    # staging
+    mina pr deploy # production
+
+Rollback to previous release:
+
+    mina rollback    # staging
+    mina pr rollback # production 
+
+General rake and mina tips:
+
+    rake -T     # list all rake commands
+    rake -T db  # list all database related commands
+    mina -T     # list all mina deploy commands
