 Public configuration files and environment for testing
 
 ## Operations
-`vagrang up` -- download sources, test
+
+### Dev
+`vagrang up` or `pxe_env=dev vagrang up` will download **whole** ubuntu image (~800mb) and netboot tarball if it aren't presented already.  
+Test server will be deployed with a PXE service, hosted preseed file and a http ubuntu mirror. This will provide a quite fast installation on test client.  
+A good choice to start of developing a new feature.
+
+### Stage
+`pxe_env=stage vagrang up` will download only netboot tarball if it isn't presented already.  
+Test server will be deployed with a PXE service but will use a global ubuntu mirror and preseed from [public gist](https://gist.github.com/b00men/40fb6781b8bc8b4d94ef15aa18c462c9). The speed of installation will depend on your connection speed.  
+A good choice to check changes before publishing in a repository.
+
+### Prod
+`pxe_env=prod vagrang up` will download only netboot tarball if it isn't presented already.  
+Test server will be deployed with a PXE service but will use a global ubuntu mirror and preseed from [repository](https://github.com/q2p-us/pxe/blob/master/preseed.txt). The speed of installation will depend on your connection speed.  
+A good choice to check current status on production.
 
 ## TODO
 - Prepare proper test's environment
-    + dev -- quick install, http based
-    + stage -- gist based (https)
-    + prod -- github based
     + emulation -- client will be connected to real server
 - Post configuration (ipmi, ssh), take from _ks_gist.cfg_
-- Move preseed to submodule
 - Add COM port configuration and testing
 - Default action -- boot from hdd
 - Simple remote trigger to install from pxe (variable for dhcp or tftpd)
