+This documentation repository consists mainly of content written in Markdown format. These files are converted into HTML for displaying on a website. Most Markdown files become a single article on the documentation site. Other files contain reusable content which is inserted into multiple articles. The repository also contains YAML files (e.g. for variable text), image files, JavaScript/TypeScript files, etc.
+
+### Using variables
+
+Within Markdown files, with the exception of the `title` field in the metadata at the start of a file, always use the Liquid syntax variables rather than text if a variable has been defined for that text. For example:
+
+| Use this variable | Don't use this text | File where variable is defined |
+| --- | --- | --- |
+| `{% data variables.product.prodname_dotcom %}` | GitHub | data/variables/product.yml |
+| `{% data variables.product.prodname_ghe_server %}` | GitHub Enterprise Server | data/variables/product.yml | 
+| `{% data variables.product.prodname_copilot_short %}` | Copilot | data/variables/product.yml |

+| `{% data variables.code-scanning.codeql_workflow %}` | CodeQL analysis workflow | data/variables/code-scanning.yml | 
+
+There are many more variables. These are stored in various YAML files within the `data/variables` directory.

 ## About knowledge bases
 
 Organization owners can create knowledge bases, bringing together Markdown documentation across one or more repositories. Organization members can then specify that knowledge base as the context for {% data variables.product.prodname_copilot_chat_dotcom_short %}, {% data variables.product.prodname_copilot_chat_short %} in {% data variables.product.prodname_vscode %}, and {% data variables.product.prodname_copilot_chat_short %} in {% data variables.product.prodname_vs %}.

+* Stay aligned on how a system works or what’s expected.
+* Learn from past work, documentation, and examples.
+* Get better help from {% data variables.product.prodname_copilot_short %} with grounded, team-curated context.
+
+## Use cases for team collaboration
+
+* **Onboarding**: Share a space with key code, docs, and checklists to help new developers get started faster.
+* **System knowledge**: Create a space for a complex system or workflow (like authentication or CI pipelines) that other people can reference.
+* **Style guides or review checklists**: Document standards and examples in a space that {% data variables.product.prodname_copilot_short %} can reference when suggesting changes.
+
+For example, a subject matter expert creates a space called “Accessibility Reviews” that includes your team’s internal accessibility checklist, product guidelines, and WCAG documentation. Developers can ask {% data variables.product.prodname_copilot_short %} questions directly in the space to ensure they're following the latest guidelines in their work.
+
+## Sharing {% data variables.product.prodname_copilot_spaces_short %}
+
+When you create a space, you can choose whether it’s owned by you or by one of your organizations. If you choose an organization:
+
+* You can share the space with others in the organization, giving read access to all organization members.
+* Other people with access can view the context, use {% data variables.product.prodname_copilot_short %} within the space, and ask questions.
+
+If you choose to create a personal space, **you can't share it with others**.
+
+To share a space with your organization:
+
+1. In the top right corner of the space, click **{% octicon "kebab-horizontal" aria-hidden="true" aria-label="kebab-horizontal" %}**, then click **{% octicon "share" aria-hidden="true" aria-label="share" %} Share**.
+1. Change the base role to "The entire organization can access".
+
+Other people in your organization can now view the space in the "Organizations" tab and use it to ask questions. Additionally, you can also click **{% octicon "link" aria-label="the link" %} Copy link** to copy the link to the space and share it with others.
+
+## Accessing shared {% data variables.product.prodname_copilot_spaces_short %}
+
+If you’re part of an organization that has shared spaces, you can access them in the **Organizations** tab on [https://github.com/copilot/spaces](https://github.com/copilot/spaces).

+1. Click **Create**.
+
+## Adding context to {% data variables.product.prodname_copilot_spaces_short %}
+
+You can add two types of context to your space:
+
+* **Instructions**: Free text that describes what {% data variables.product.prodname_copilot_short %} should focus on within this space. Include its areas of expertise, what kinds of tasks it should help with, and what it should avoid.

+
+   For example:
+
+   > You are a SQL generator. Your job is to take the sample queries and data schemas defined in the attached files and and generate SQL queries based on the user's goals.
+
+* **References**: You can add any code hosted in {% data variables.product.github %} repositories, including public and private repositories. You can also add free-text content, such as transcripts or notes.
+
+   >[!TIP] You don’t need formal docs to get value from {% data variables.product.prodname_copilot_spaces_short %}. Try pasting in a Slack thread, a video call summary, or even bullet-point notes.
+
+This context will be used to provide more relevant answers to your questions. Additionally, {% data variables.product.prodname_copilot_spaces_short %} will always refer to the latest version of the code on the `main` branch of the repository.
+
+## Using {% data variables.product.prodname_copilot_spaces_short %}
+
+Once you've added context to your space, you can ask {% data variables.product.prodname_copilot_short %} questions in the chat interface. Your chat will be grounded in the context you've added.
+
+You can also change the large language model (LLM) used for your space by selecting the **CURRENT-MODEL** {% octicon "chevron-down" aria-hidden="true" aria-label="chevron-down" %} dropdown menu, then clicking the AI model of your choice.

+
+If you're starting a new feature, trying to understand a system, or picking up a task in a codebase you’re still learning, {% data variables.product.prodname_copilot_spaces %} can help you:
+
+* Stay focused by organizing the context you need in one place.
+* Get better help from {% data variables.product.prodname_copilot_short %} by grounding it in relevant code and documentation.
+* Move faster without switching between tools or asking others for background information.
+
+To create a space, go to [https://github.com/copilot/spaces](https://github.com/copilot/spaces), and click **Create space**.
+
+Below are some examples of how to use {% data variables.product.prodname_copilot_spaces_short %} to help you with development work.
+
+## Developing a new feature
+
+When working on a specific feature, you can save time and produce higher-quality results by using a space. Add the relevant code, a product spec, and any supporting materials—like notes from a design review or image descriptions of mockups. {% data variables.product.prodname_copilot_short %} can help you:
+
+* Summarize how the current implementation works.
+* Suggest changes or additions based on the spec.
+* Draft a first implementation or outline next steps.
+* Flag missing elements or inconsistencies.
+
+**Instructions**:
+> This space contains the new user registration form for a healthcare nonprofit providing low-cost testing. It is built using React and Tailwind.
+
+**Suggested prompt**:
+> How should I add support for 2FA?
+
+## Defining the logic for a small, frequent task
+
+When working on repetitive tasks like tracking telemetry events or handling event emissions, it’s useful to document the logic once and share it with others through {% data variables.product.prodname_copilot_spaces_short %}. This allows everyone to stay consistent and saves time when performing the task. {% data variables.product.prodname_copilot_short %} can assist by:
+
+* Suggesting efficient patterns based on your previous work.
+* Helping write reusable functions or templates.
+* Reviewing the logic to ensure it aligns with project standards.
+* Providing examples of how similar tasks have been handled in the codebase.
+
+**Instructions**:
+> You help developers implement telemetry events. You should (1) validate what the user's goals are for the event, (2) propose a new event structure based on examples of existing events (and using the common telemetry schema), and (3) create a new version of the telemetry config file.
+
+**Suggested prompt**:
+> Help me log when a user clicks on an in-app notification.
+
+## Sharing knowledge with teammates
+
+In situations where people tend to ask similar questions, such as how authentication or search works in your project, {% data variables.product.prodname_copilot_short %} can help:
+
+* Explain how the code works.
+* Answer questions grounded in the latest documentation.
+* Guide new team members on the best practices.
+
+**Instructions**:
+> You contain the code and documentation associated with our authentication system.  
+
+**Suggested prompt**:
+> How does SSO work?
+
+## Next steps
+
+Once you’ve created a space to help with development tasks, consider sharing it with your team to reduce handoffs and repeated questions. See [AUTOTITLE](/copilot/using-github-copilot/copilot-spaces/collaborating-with-your-team-using-copilot-spaces).

+## Using {% data variables.product.prodname_copilot_spaces %} to improve test suggestions
+
+{% data variables.product.prodname_copilot_spaces %} is a feature that allows you to organize and share task-specific context with {% data variables.product.prodname_copilot_short %}. This can help improve the relevance of the suggestions you receive. By providing {% data variables.product.prodname_copilot_short %} with more context about your project, you can get better test suggestions.
+
+For example, you could create a space that includes:
+
+* The module you’re testing (like `payments.js`)
+* The current test suite (like `payments.test.js`)
+* A test coverage report or notes about what's missing
+
+In the space, you can ask {% data variables.product.prodname_copilot_short %} questions like:
+
+> What test cases are missing in `payments.test.js` based on the logic in `payments.js`?
+
+Or:
+
+> Write a unit test for the refund logic in `refund.js`, following the structure in the existing test suite.
+
+For more information about using {% data variables.product.prodname_copilot_spaces %}, see [AUTOTITLE](/copilot/using-github-copilot/copilot-spaces/about-organizing-and-sharing-context-with-copilot-spaces).
