+# 🎭 Currents - Playwright - GitLab CI/CD
+
+This repo showcases [Playwright](https://playwright.dev/) integration with [Currents](https://currents.dev). The example is based on https://github.com/MarcusFelling/demo.playwright, the [basic](./basic) test scenarios.
+
+<p align="center">
+  <img width="830" src="https://static.currents.dev/currents-playwright-banner-gh.png" />
+</p>
+
+See the [`.gitlab-ci.yml`](.gitlab-ci.yml) file - it created a GitLab CI pipeline with 3 workers using 3 [Playwright Shards](https://playwright.dev/docs/test-sharding).
+
+Example command:
+
+```sh
+npx pwc --key $CURRENTS_RECORD_KEY --project-id bnsqNa --shard=$CI_NODE_INDEX/$CI_NODE_TOTAL
+```
+
+## Setup
+
+- Create an account at https://app.currents.dev and grab the **Project ID** and **Record Key**.
+- Add `CURRENTS_RECORD_KEY` as [GitLab CI/CD Secrets](https://docs.gitlab.com/ee/ci/variables/) (make sure it's not protected)
+- [Optional] Add `CURRENTS_API_KEY` as [GitLab CI/CD Secrets](https://docs.gitlab.com/ee/ci/variables/) (only used in the examples with `npx currents api` commands)
+
+Additional resources:
+
+- Playwright Features on Currents: https://currents.dev/playwright
+- Integration Documentation: https://currents.dev/readme/integration-with-playwright/currents-playwright
+- CI Build ID Guide: https://currents.dev/readme/guides/cypress-ci-build-id
+
+## Additional examples
+
+- [`.gitlab-ci.yml`](.gitlab-ci.yml) - The basic 3 parrallel job sharded pipeline
+- Examples of running only the failed tests when retrying a CI pipeline/job
+  - For `playwright test` (with currents reporter) : [`./gitlab/ci/with-reruns-reporter.yml`](./gitlab/ci/with-reruns-reporter.yml)
+  - For `pwc` : [`./gitlab/ci/with-reruns-pwc.yml`](./gitlab/ci/with-reruns-pwc.yml) 
+  - For `pwc-p` (orchestration) : [`./gitlab/ci/with-reruns-pwcp.yml`](./gitlab/ci/with-reruns-pwcp.yml) 
+
+## GitLab CI Playwright Results
+
+The results are being reported to Currents for more efficient troubleshooting, and monitoring test suite flakiness and performance.
+
+Currents will collect the following information:
+
+- console output
+- screenshots
+- videos
+- trace files
+- timing
+- outcomes
+- flaky tests
+- error details
+- tags for more convenient management of the tests
+
+### GitLab Merge Request Notes
+
+Take a look at the example merge request: https://gitlab.com/currents.dev/gitlab-playwright-currents/-/merge_requests/3
+
+When [GitLab integration](https://currents.dev/readme/integrations/gitlab) is enabled, Currents will post a Merge Commit note with run results:
+
+<p align="center">
+  <img width="830" src="https://static.currents.dev/currents-gitlab-merge-note.png" />
+</p>
+
+In addition, Currents will post an [External Status check](https://docs.gitlab.com/ee/user/project/merge_requests/status_checks.html) for every Playwright project configured. For example:
