process: improve readme
## Introduction
-This plugin utilizes the pluginprocess library in order to execute arbitrary other
-plugins in an own process, acting as a proxy itself. Therefore it is not required
-to explicitly change a plugin's implementation if it shall be executed in an own
-process.
+The process plugin uses the `pluginprocess` library in order to execute other plugins inside an own process.
+This is useful for plugins which cause memory leaks to be isolated in an own process. Furthermore
+this is useful for runtimes or libraries that cannot be reinitialized in the same process after they
+have been used.
## Usage
-Mount this plugin and specify the plugin configuration parameter `plugin` to a plugin that exists on the system. The proxied plugin will then be executed in a separate process and this plugin handles the communication between the processes.
