# Instructions

VS Code commands must always define a `title`, independent of its category, visibility or location. We use a few patterns for each "kind" of command, with some characteristics, described below:

* Regular commands: By default, all commands should be accessible in the Command Palette, must define a `category`, and don't need an `icon`, unless the command will be used in the Side Bar.

* Side Bar commands: Its name follows a special pattern, starting with underscore (`_`) and suffixed with `#sideBar`, like `_extensionId.someCommand#sideBar` for instance. Must define an `icon`, and may or may not have some rule for `enablement`. Side Bar exclusive commands should not be visible in the Command Palette. Contributing it to the `view/title` or `view/item/context`, we must inform _order/position_ that it will be displayed, and we can use terms "relative to other command/button" in order to you identify the correct `group` to be used. Also, it's a good practice to define the condition (`when`) for the new command is visible.
