+## Artifacts
+
+It allows you to share data between jobs in a workflow and store data once the workflow has been completed. We can use the `upload-artifact` and `download-artifact` actions to upload and download artifacts.
+
+```yaml
+name: Share data between jobs
+
+on: [push]
+
+jobs:
+  job_1:
+    name: Generate Random Number
+    runs-on: ubuntu-latest
+    steps:
+      - shell: bash
+        run: |
+          echo $((RANDOM % 100)) > random-number.txt
