 Travis CI and {% data variables.product.prodname_actions %} both include default environment variables that you can use in your YAML files. For {% data variables.product.prodname_actions %}, you can see these listed in "[Default environment variables](/actions/reference/environment-variables#default-environment-variables)."
 
+To help you get started, this table maps some of the common Travis CI variables to {% data variables.product.prodname_actions %} variables with similar functionality:
+
+| Travis CI | {% data variables.product.prodname_actions %}| {% data variables.product.prodname_actions %} description |
+| ---------------------|------------ |------------ |
+| `CI` | [`CI`](/actions/reference/environment-variables#default-environment-variables) | Allows your software to identify that it is running within a CI workflow. Always set to `true`.|
+| `TRAVIS` | [`GITHUB_ACTIONS`](/actions/reference/environment-variables#default-environment-variables) | Use `GITHUB_ACTIONS` to identify whether tests are being run locally or by {% data variables.product.prodname_actions %}. Always set to `true` when {% data variables.product.prodname_actions %} is running the workflow.|
+| `TRAVIS_BRANCH` | [`github.head_ref`](/actions/reference/context-and-expression-syntax-for-github-actions#github-context) or [`github.ref`](/actions/reference/context-and-expression-syntax-for-github-actions#github-context) | Use `github.ref` to identify the branch or tag ref that triggered the workflow run. For example, `refs/heads/<branch_name>` or `refs/tags/<tag_name>`. Alternatvely, `github.head_ref` is the source branch of the pull request in a workflow run; this property is only available when the workflow event trigger is a `pull_request`.  |
+| `TRAVIS_BUILD_DIR` | [`github.workspace`](/actions/reference/context-and-expression-syntax-for-github-actions#github-context) | Returns the default working directory for steps, and the default location of your repository when using the [`checkout`](https://github.com/actions/checkout) action. |
+| `TRAVIS_BUILD_NUMBER` | [`GITHUB_RUN_NUMBER`](/actions/reference/environment-variables#default-environment-variables) | {% data reusables.github-actions.run_number_description %} |
+| `TRAVIS_COMMIT` | [`GITHUB_SHA`](/actions/reference/environment-variables#default-environment-variables) | Returns the SHA of the commit that triggered the workflow. |
+| `TRAVIS_EVENT_TYPE` | [`github.event_name`](/actions/reference/context-and-expression-syntax-for-github-actions#github-context) |  The name of the webhook event that triggered the workflow. For example, `pull_request` or `push`. |
+| `TRAVIS_JOB_ID` | [`github.job`](/actions/reference/context-and-expression-syntax-for-github-actions#github-context) | The [`job_id`](/actions/reference/workflow-syntax-for-github-actions#jobsjob_id) of the current job. |
+| `TRAVIS_OS_NAME` | [`runner.os`](/actions/reference/context-and-expression-syntax-for-github-actions#runner-context) | The operating system of the runner executing the job. Possible values are `Linux`, `Windows`, or `macOS`. |
+| `TRAVIS_PULL_REQUEST` | [`github.event.pull_request.number`](/developers/webhooks-and-events/webhook-events-and-payloads#pull_request) | The pull request number. This property is only available when the workflow event trigger is a `pull_request`. |
+| `TRAVIS_REPO_SLUG` | [`GITHUB_REPOSITORY`](/actions/reference/environment-variables#default-environment-variables) | The owner and repository name. For example, `octocat/Hello-World`. |
+| `TRAVIS_TEST_RESULT` | [`job.status`](/actions/reference/context-and-expression-syntax-for-github-actions#job-context) | The current status of the job. Possible values are `success`, `failure`, or `cancelled`. |
+| `USER` | [`GITHUB_ACTOR`](/actions/reference/environment-variables#default-environment-variables) | The name of the person or app that initiated the workflow. For example, `octocat`. |

 ### Parallel job processing
 
 Travis CI can use `stages` to run jobs in parallel. Similarly, {% data variables.product.prodname_actions %} runs `jobs` in parallel. For more information, see "[Creating dependent jobs](/actions/learn-github-actions/managing-complex-workflows#creating-dependent-jobs)."
