 IntelliJ IDEA can be modified and adjusted for particular purposes by adding plugins.
 All the plugins which are already available for download can be found at [JetBrains Plugin Repository] (https://plugins.jetbrains.com/).
 Most commonly used types of plugins are:
------
+
 * Custom language support
 * Framework integration
 * Tools integration
 * User interface add-ons
 The majority of already existing plugins are complex, so they combine multiple function, but generally these types can be marked out

 #Custom language support
+
+Custom language support provides basic functionality for working with a particular programming language. This includes:
+
+* File type recognition
+* Lexical analysis and
+* Syntax highlighting
+* Formatting
+* Code insight and code completion
+* Inspections and quickfixes
+* Intention actions
+
+[Tutorial] (http://confluence.jetbrains.com/display/IntelliJIDEA/Custom+Language+Support) for a custom language support implementations

 #Framework integration
+Framework integrations consists of improved code insight features which are typical for a given framework and
+option to use specific functionality of a framework directly from the IDE. May include language support elements
+in case of a custom syntax or DSL.
+
+* Specific code insight
+* Direct access to the framework's functionality

 #Tools integration
+Tools integration makes possible to manipulate third-party tools and components directly from the IDE without making a context switch. This implies:
+
+* Implementation of additional actions 
+* Related UI components
+* Access to external resources
+
+[TeamCity integration] (https://plugins.jetbrains.com/plugin/1820?pr=idea) plugin as an example
+
 #User interface add-ons
+Plugins from these group apply different changes to the standard user interface of the IDE. Newly added components can either be interactive and provide new functionality, or be just a visual modification.
