-#### Task executed always
+#### Always executed tasks
 
 Sometimes it's convenient to define tasks which should be executed every time without explicit invocation. For example for setting the up the default environment, properties, etc. To achieve that one should specify the **always** property for a task:
 
 ```
+<?php
+namespace taskman;
+
 task('setup_env', ['always' => true], 
    function() {});
 ``` 
+
+### Build properties
+
+It's possible to specify miscellaneous build properties to setup a proper build environment conditions. There's a set of routines which provides taskman for properties manipulation.
+
+### Setting a property
+
+Use **set** built-in function:
+
+```
+<?php
+namespace taskman;
+
+task('setup_env', ['always' => true], 
+   function() {
+      set("IOS_APP_ID", "4242jfhFD");
+   });
+``` 
+
+### Getting a property
+
+Use **get** built-in function:
+
+```
+<?php
+namespace taskman;
+
+task('build_ios', 
+   function() {
+      shell("xcode build app " . get("IOS_APP_ID"));
+   });
+```
