**Product Help:** [Run/Debug Configuration](https://www.jetbrains.com/idea/help/run-debug-configuration.html)
</microformat>
These series of steps show how to register and implement a simple Run Configuration.
Run Configurations are used to run internal and external processes from within IntelliJ Platform based products.
Consider the **runConfiguration** sample plugin available in the [code samples](%gh-sdk-samples%/run_configuration).
See [Code Samples](code_samples.md) on how to set up and run the plugin.
## Pre-Requirements
Create an empty plugin project.
See the [](creating_plugin_project.md) section for details.
## Register a New ConfigurationType
Add new `com.intellij.configurationType` extension to the [plugin.xml](%gh-sdk-samples%/run_configuration/src/main/resources/META-INF/plugin.xml)
```xml
<extensions defaultExtensionNs="com.intellij">
<configurationType
implementation="org.jetbrains.sdk.runConfiguration.DemoRunConfigurationType"/>
</extensions>
```
## Implement ConfigurationType
Implement [`ConfigurationType`](%gh-ic%/platform/execution/src/com/intellij/execution/configurations/ConfigurationType.java) interface registered in the Step 1.
```java
```
{src="run_configuration/src/main/java/org/jetbrains/sdk/runConfiguration/DemoRunConfigurationType.java"}
## Implement a ConfigurationFactory
Implement a new [`ConfigurationFactory`](%gh-ic%/platform/execution/src/com/intellij/execution/configurations/ConfigurationFactory.java) through which custom run configurations will be created.
```java
```
{src="run_configuration/src/main/java/org/jetbrains/sdk/runConfiguration/DemoConfigurationFactory.java"}
Implement corresponding configuration options class extending [`RunConfigurationOptions`](%gh-ic%/platform/execution/src/com/intellij/execution/configurations/RunConfigurationOptions.kt) to store settings.
```java
```
{src="run_configuration/src/main/java/org/jetbrains/sdk/runConfiguration/DemoRunConfigurationOptions.java"}
## Implement a Run Configuration
To make your changes visible from the UI, implement a new Run Configuration.
**Note:** In most of the cases you can derive a custom Run Configuration class from the [`RunConfigurationBase`](%gh-ic%/platform/execution/src/com/intellij/execution/configurations/RunConfigurationBase.java).
If you need to implement specific settings externalization rules and I/O behaviour, use [`RunConfiguration`](%gh-ic%/platform/execution/src/com/intellij/execution/configurations/RunConfiguration.java) interface.
```java
```
{src="run_configuration/src/main/java/org/jetbrains/sdk/runConfiguration/DemoRunConfiguration.java"}
## Create and Implement Run Configuration UI Form
Make sure _UI Designer_ plugin is [enabled](https://www.jetbrains.com/help/idea/managing-plugins.html).
Create a new [UI form](https://www.jetbrains.com/help/idea/designing-gui-major-steps.html) that defines, how an inner part of the new Run Configuration should look like.
Default Run Configuration will be looking like this:

## Bind the UI Form
The UI Form should be bound with a Java class responsible for handling UI components logic.
```java
```
{src="run_configuration/src/main/java/org/jetbrains/sdk/runConfiguration/DemoSettingsEditor.java"}
## Compile and Run the Plugin
Refer to [Running and Debugging a Plugin](creating_plugin_project.md#executing-the-plugin).
After going through the steps described above you can create a custom Run Configuration from your plugin.
