 * **[Repository custom instructions](#about-repository-custom-instructions)** apply to conversations within the context of a specific repository. They are useful for defining project-specific coding standards, frameworks, or tools. For example, you can specify that a repository uses TypeScript and a particular library, ensuring consistent responses for all contributors.
 * **[Organization custom instructions](#about-organization-custom-instructions)** (public preview) apply to conversations within the context of an organization on the {% data variables.product.github %} website. They are ideal for enforcing organization-wide preferences, such as a common language or security guidelines. Organization custom instructions can only be set by organization owners for organizations with a {% data variables.copilot.copilot_enterprise_short %} subscription.

 Custom instructions consist of natural language instructions and are most effective when they are short, self-contained statements. Consider the scope over which you want the instruction to apply when choosing whether to add an instruction on the personal, repository, or organization level.
