+## Preparation
+
+* Build as class library.
+* Add reference to ```VAR.Toolbox``` for interface declarations and utilities.
+* Use the interfaces to extend functionality:
+  * ```IToolForm```: Tool window.
+  * ```IToolPanel```: Tool panels in the main window. Try to fit all on 200px width.
+  * ```ITextCoder```: Text codification clases.
+  * ```IProxyCmdExecutor```: Proxy command executors, mainly for remote executions.
+
+## Usage
+
+Put the generated assembly near ```VAR.Toolbox.exe``` it will load as plug-ins any assembly that starts with ```VAR.Toolbox```
