+# CI for InstructLab Eval
+
+Before running any testing locally, ensure you have run `pip install -r requirements-dev.txt` in your environment.
+
+## Unit tests
+
+Unit tests are designed to test specific Eval components or features in isolation. Generally, new code should be adding or modifying unit tests.
+
+All unit tests currently live in the `tests/` directory and are run with [pytest](https://docs.pytest.org/) via [tox](https://tox.wiki/).
+
+To run the unit tests, you can run `tox -e unit` or `tox -e unitcov` if you want to generate coverage metrics as well.
+
+In CI, the tests are run with Python 3.10 - 3.11 on Ubuntu and MacOS runners - you can see the details [here](https://github.com/instructlab/eval/blob/main/.github/workflows/test.yml)
+
+## Functional tests
+
+Functional tests are designed to test Eval components or features in tandem, but not necessarily as part of a complex workflow. New code may or may not need a functional test but should strive to implement one if possible.
+
+The functional test script is Shell-based and can be found at `scripts/functional-tests.sh`.
+
+To run the functional tests, you can run `tox -e functional`.
+
+In CI, the tests are run with Python 3.10 - 3.11 on Ubuntu and MacOS runners - you can see the details [here](https://github.com/instructlab/eval/blob/main/.github/workflows/test.yml)
+
+## End-to-end (E2E) tests
+
+InstructLab Eval has several end-to-end jobs that run to ensure compatibility with the [InstructLab Core](https://github.com/instructlab/instructlab) project.
+You can see details about the types of jobs being run in the matrix below.
+
+For more details about the E2E scripts themselves, see [the InstructLab Core documentation](https://github.com/instructlab/instructlab/blob/main/docs/maintainers/ci.md#end-to-end-e2e-tests).
+
+### Current E2E Jobs
+
+| Name | T-Shirt Size | Runner Host | Instance Type | OS | GPU Type | Script | Flags | Runs when? | Slack/Discord reporting? |
+| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
+| [`e2e-nvidia-l4-x1.yml`](https://github.com/instructlab/sdg/blob/main/.github/workflows/e2e-nvidia-l4-x1.yml) | Medium | AWS |[`g6.8xlarge`](https://aws.amazon.com/ec2/instance-types/g5/) | CentOS Stream 9 | 1 x NVIDIA L4 w/ 24 GB VRAM | `e2e-ci.sh` | `m` | Pull Requests, Push to `main` or `release-*` branch | No |
+| [`e2e-nvidia-l40s-x4.yml`](https://github.com/instructlab/sdg/blob/main/.github/workflows/e2e-nvidia-l40s-x4.yml) | Large | AWS |[`g6e.12xlarge`](https://aws.amazon.com/ec2/instance-types/g6e/) | CentOS Stream 9 | 4 x NVIDIA L40S w/ 48 GB VRAM (192 GB) | `e2e-ci.sh` | `l` | Manually by Maintainers, Automatically against `main` branch at 4PM UTC | Yes |
+
+### Discord/Slack reporting
+
+Some E2E jobs send their results to the channel `#e2e-ci-results` via the `Son of Jeeves` bot in both Discord and Slack. You can see which jobs currently have reporting via the "Current E2E Jobs" table above.
+
+In Slack, this has been implemented via [the official Slack GitHub Action](https://github.com/slackapi/slack-github-action?tab=readme-ov-file#technique-2-slack-app).
+In Discord, we use [actions/actions-status-discord](https://github.com/sarisia/actions-status-discord) and the built-in channel webhooks feature.
+
+### Triggering an E2E job via GitHub Web UI
+
+For the E2E jobs that can be launched manually, they take an input field that
+specifies the PR number or git branch to run them against. If you run them
+against a PR, they will automatically post a comment to the PR when the tests
+begin and end so it's easier for those involved in the PR to follow the results.
+
+1. Visit the [Actions tab](https://github.com/instructlab/eval/actions).
+2. Click on one of the E2E workflows on the left side of the page.
+3. Click on the `Run workflow` button on the right side of the page.
+4. Enter a branch name or a PR number in the input field.
+5. Click the green `Run workflow` button.
