 You can configure a job's dependencies with other jobs; by default, jobs have no dependencies and run in parallel. When a job takes a dependency on another job, it waits for the dependent job to complete before running.
 
+You can also use a **matrix** to run the same job multiple times, each with a different combination of variables—like operating systems or language versions.
+
 For example, you might configure multiple build jobs for different architectures without any job dependencies and a packaging job that depends on those builds. The build jobs run in parallel, and once they complete successfully, the packaging job runs.

+## Adding a matrix strategy to your workflow job
+
+Use `jobs.<job_id>.strategy.matrix` to define a matrix of different job configurations. Within your matrix, define one or more variables followed by an array of values. For example, the following matrix has a variable called `version` with the value `[10, 12, 14]` and a variable called `os` with the value `[ubuntu-latest, windows-latest]`:
+
+```yaml
+jobs:
+  example_matrix:
+    strategy:
+      matrix:
+        version: [10, 12, 14]
+        os: [ubuntu-latest, windows-latest]
+```
+
+A job will run for each possible combination of the variables. In this example, the workflow will run six jobs, one for each combination of the `os` and `version` variables.
+
+The above matrix will create the jobs in the following order.
+
+* `{version: 10, os: ubuntu-latest}`
+* `{version: 10, os: windows-latest}`
+* `{version: 12, os: ubuntu-latest}`
+* `{version: 12, os: windows-latest}`
+* `{version: 14, os: ubuntu-latest}`
+* `{version: 14, os: windows-latest}`
+
+For reference information and examples, see [AUTOTITLE](/actions/reference/workflow-syntax-for-github-actions#jobsjob_idstrategymatrix).
+
+## Using contexts to create matrices
+
+To create matrices with information about workflow runs, variables, runner environments, jobs, and steps, access contexts using the {% raw %}`${{ <context> }}`{% endraw %} expression syntax. For more information about contexts, see [AUTOTITLE](/actions/learn-github-actions/contexts).
+
+For example, the following workflow triggers on the `repository_dispatch` event and uses information from the event payload to build the matrix. When a repository dispatch event is created with a payload like the one below, the matrix `version` variable will have a value of `[12, 14, 16]`. For more information about the `repository_dispatch` trigger, see [AUTOTITLE](/actions/using-workflows/events-that-trigger-workflows#repository_dispatch).
+
+```json
+{
+  "event_type": "test",
+  "client_payload": {
+    "versions": [12, 14, 16]
+  }
+}
+```
+
+```yaml
+on:
+  repository_dispatch:
+    types:
+      - test
+
+jobs:
+  example_matrix:
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        version: {% raw %}${{ github.event.client_payload.versions }}{% endraw %}
+    steps:
+      - uses: {% data reusables.actions.action-setup-node %}
+        with:
+          node-version: {% raw %}${{ matrix.version }}{% endraw %}
+```
 
 ## Expanding or adding matrix configurations
 
-{% data reusables.actions.jobs.matrix-include %}
+To expand existing matrix configurations or to add new configurations, use `jobs.<job_id>.strategy.matrix.include`. The value of `include` is a list of objects.
+
+For example, consider the following matrix.
+
+```yaml
+strategy:
+  matrix:
+    fruit: [apple, pear]
+    animal: [cat, dog]
+    include:
+      - color: green
+      - color: pink
+        animal: cat
+      - fruit: apple
+        shape: circle
+      - fruit: banana
+      - fruit: banana
+        animal: cat
+```
+
+This will result in six jobs with the following matrix combinations.
+
+* `{fruit: apple, animal: cat, color: pink, shape: circle}`
+* `{fruit: apple, animal: dog, color: green, shape: circle}`
+* `{fruit: pear, animal: cat, color: pink}`
+* `{fruit: pear, animal: dog, color: green}`
+* `{fruit: banana}`
+* `{fruit: banana, animal: cat}`
+
+Each `include` entry was applied in the following ways.
+
+* `{color: green}` is added to all of the original matrix combinations because it can be added without overwriting any part of the original combinations.
+* `{color: pink, animal: cat}` adds `color:pink` only to the original matrix combinations that include `animal: cat`. This overwrites the `color: green` that was added by the previous `include` entry.
+* `{fruit: apple, shape: circle}` adds `shape: circle` only to the original matrix combinations that include `fruit: apple`.
+* `{fruit: banana}` cannot be added to any original matrix combination without overwriting a value, so it is added as an additional matrix combination.
+* `{fruit: banana, animal: cat}` cannot be added to any original matrix combination without overwriting a value, so it is added as an additional matrix combination. It does not add to the `{fruit: banana}` matrix combination because that combination was not one of the original matrix combinations.
+
+For reference and example configurations, see [AUTOTITLE](/actions/reference/workflow-syntax-for-github-actions#jobsjob_idstrategymatrixinclude).
 
-### Example: Expanding configurations
+## Excluding matrix configurations
 
-{% data reusables.actions.jobs.matrix-expand-with-include %}
+To remove specific configurations defined in the matrix, use `jobs.<job_id>.strategy.matrix.exclude`.
+
+For example, the following workflow will run nine jobs: one job for each of the 12 configurations, minus the one excluded job that matches `{os: macos-latest, version: 12, environment: production}`, and the two excluded jobs that match `{os: windows-latest, version: 16}`.
+
+```yaml
+strategy:
+  matrix:
+    os: [macos-latest, windows-latest]
+    version: [12, 14, 16]
+    environment: [staging, production]
+    exclude:
+      - os: macos-latest
+        version: 12
+        environment: production
+      - os: windows-latest
+        version: 16
+runs-on: {% raw %}${{ matrix.os }}{% endraw %}
+```

+
+## Using an output to define two matrices
+
+You can use the output from one job to define matrices for multiple jobs.
+
+For example, the following workflow demonstrates how to define a matrix of values in one job, use that matrix in a second jobs to produce artifacts, and then consume those artifacts in a third job. Each artifact is associated with a value from the matrix.
+
+```yaml copy
+name: shared matrix
+on:
+  push:
+  workflow_dispatch:
+
+jobs:
+  define-matrix:
+    runs-on: ubuntu-latest
+
+    outputs:
+      colors: {% raw %}${{ steps.colors.outputs.colors }}{% endraw %}
+
+    steps:
+      - name: Define Colors
+        id: colors
+        run: |
+          echo 'colors=["red", "green", "blue"]' >> "$GITHUB_OUTPUT"
+
+  produce-artifacts:
+    runs-on: ubuntu-latest
+    needs: define-matrix
+    strategy:
+      matrix:
+        color: {% raw %}${{ fromJSON(needs.define-matrix.outputs.colors) }}{% endraw %}
+
+    steps:
+      - name: Define Color
+        env:
+          color: {% raw %}${{ matrix.color }}{% endraw %}
+        run: |
+          echo "$color" > color
+      - name: Produce Artifact
+        uses: {% data reusables.actions.action-upload-artifact %}
+        with:
+          name: {% raw %}${{ matrix.color }}{% endraw %}
+          path: color
+
+  consume-artifacts:
+    runs-on: ubuntu-latest
+    needs:
+    - define-matrix
+    - produce-artifacts
+    strategy:
+      matrix:
+        color: {% raw %}${{ fromJSON(needs.define-matrix.outputs.colors) }}{% endraw %}
+
+    steps:
+    - name: Retrieve Artifact
+      uses: {% data reusables.actions.action-download-artifact %}
+      with:
+        name: {% raw %}${{ matrix.color }}{% endraw %}
+
+    - name: Report Color
+      run: |
+        cat color
+```
 
-### Example: Adding configurations
+## Handling failures
 
-{% data reusables.actions.jobs.matrix-add-with-include %}
+To control how job failures are handled, use `jobs.<job_id>.strategy.fail-fast` and `jobs.<job_id>.continue-on-error`.
 
-## Excluding matrix configurations
+You can use `jobs.<job_id>.strategy.fail-fast` and `jobs.<job_id>.continue-on-error` together. For example, the following workflow will start four jobs. For each job, `continue-on-error` is determined by the value of `matrix.experimental`. If any of the jobs with `continue-on-error: false` fail, all jobs that are in progress or queued will be cancelled. If the job with `continue-on-error: true` fails, the other jobs will not be affected.
 
-{% data reusables.actions.jobs.matrix-exclude %}
+```yaml
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    continue-on-error: {% raw %}${{ matrix.experimental }}{% endraw %}
+    strategy:
+      fail-fast: true
+      matrix:
+        version: [6, 7, 8]
+        experimental: [false]
+        include:
+          - version: 9
+            experimental: true
+```
