Hadolint Rule Explainer is a free Chrome extension designed to assist developers by providing quick explanations of Hadolint rules. When users select specific text that includes rules such as DL3002 or SC2015, the extension activates a context menu option. This feature allows users to easily access detailed descriptions of the selected rules through a convenient popup interface.

The extension not only clarifies the meaning of each rule but also enhances the learning experience by linking directly to the official Hadolint and ShellCheck documentation. This makes it a valuable tool for developers looking to improve their coding practices and understand the implications of various rules in their projects.
