+## Task 1
+
+**Link to a successful run:**  
+
+https://github.com/Uiyrte/F25-DevOps-Intro/actions/runs/17895083050
+
+
+**Learned key concepts**
+
+ **Workflow** is an automated process described in a YAML file, which is placed in the .github/workflows/.
+ **Trigger** (on: push) is an event that triggers a workflow. In this case, it is a push commit to a repository branch.
+ **Job** is a set of steps that are executed on a single runner. The current workflow uses one job called Explore-GitHub-Actions.
+ **Steps** are sequential actions within a job. They can be either custom commands (run:) or built-in actions (uses:).
+ **Runner** is a server provided by GitHub, on which jobs are executed. This task uses ubuntu-latest.
+
+
+**What triggered the workflow to run**
+
+Workflow was activated automatically after a commit with the github-actions-demo.yml file was pushed to the feature/lab3 branch. The push event acted as a trigger that initiated the process execution.
