 # CodeX Editor API
+
+Each Block instance provided API by default. Plugin and Tune Developers 
+can use Editor API as they want.
+
+Example:
+
+1) Developing Tunes: 
+
+Create Class that implements block-tune.ts
+
+Your Tune's constructor gets two arguments: 
+ - {Object} api - object contains public methods from modules 
+ - {Object} settings - settings contains block default state. 
+ This object could have information about cover, anchor and so on.

 # CodeX Editor Toolbar Settings Module
+
+Toolbar Module has space for Block settings. Settings divided into:
+ - space for plugin's settings, that is described by «Plugin»'s Developer
+ - space for default settings. This option is also can be implemented end expanded
+
+They difference between zones is that the first option is specified by plugin
+and each Block may have different options, when second option is for every Block
+regardless to the plugin's option.
+
+### Let's look the examples:
+
+«Plugin»'s Developers need to expand «makeSettings» method that returns HTML. 
+Every user action will be handled by itself. So, you can easily write
+callbacks that switches your content or makes better. For more information
+read [Tools](tools.md).
+
+«Tune»'s Developers need to implement core-provided interface to develop
+tunes that will be appeared in Toolbar-settings zone.
+
+Tunes must expand two important methods:
+ - `render()` - returns HTML and it is appended to the default settings zone
+ - `save()` - extracts important information to be saved
+ 
+No restrictions. Handle user action by yourself
