    "### Terminologia Github Actions\n",
    " - *Workflow* - workflow odpowiada \"Pipeline\" z Jenkinsa.\n",
    " - *Job* - workflow składa się z jednego lub kilku \"jobs\". Każdy z nich może być wykonywany równolegle na innej maszynie (patrz \"runner\")\n",
    " - *Step* - odpowiednik \"Stage\" z Jenkinsa - służu do grupowania \"Actions\"\n",
    " - *Action* - odpowiednik \"Step\" z Jenkinsa - pojedyncze polecenie do wykonania, np. dodanie komentarze do Pull requesta, wykonanie polecenia systemowego itp.\n",
    " - *Runner* - odpowiednik Jenkinsowego \"Agent\" - serwer, na którym mogą być wykonywane zadania (\"jobs\")\n",
    "   - *Github-hosted runner* - serwer utrzymywany przez Github (2-core CPU, 7 GB RAM, 14 GB SSD). Windows, Linux albo macOS\n",
    "   - *Self-hosted runner* - nasz własny serwer, z zinstalowaną aplikacją [Github actions runner](https://github.com/actions/runner)\n",
    " - *Event* - zdażenie, które odapala (\"triggers\") uruchomienie Workflow. Np. wypchnięcie zmiany do repozytorium (\"push\"), utworzenie Pull requesta. [Pełna lista](https://docs.github.com/en/actions/reference/events-that-trigger-workflows)"

    "### Definicja workflow\n",
    " - Workflow definiuje się w plikach YAM(o rozszerzeniu `*.yml` albo `*.yaml`) umieszczonych w specjalnym folderze `.github/workflows/` wewnątrz repozytorium\n",
    " - Pełna składnia jest opisana [tutaj](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions)\n",
    " - Podstawowe pola:\n",
    "   - `name` [opcjonalna] - nazwa, pod którą workflow/step będzie widoczny w UI. Domyślnie ścieżka do pliku yaml\n",
    "   - `on` - definiuje kiedy workflow ma być odpalony\n",
    "   - `jobs` - grupuje razem \"zadania\" do wykonania. Każde może być wykonane na innym \"runnerze\". Domyślnie wykonywane są równolegle (ale możemy definiować [zależności między jobami](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idneeds), co powoduje wykonanie ich sekwencyjnie\n",
    "   - `runs-on` - parametr joba, definujący na jakiej maszynie wirtualnej ma być uruchomiony (np. `ubuntu-latest`)\n",
    "   - `uses` - umożliwia użycie gotowych akcji zdefiniowanych przez nas, albo przez innych użytkowników, np. `-uses: actions/checkout@v2` spowoduje checkout plików z repozytorium\n",
    "   - `run` - pozwala uruchomić dowolne ([dostępne/zainstalowane](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#preinstalled-software)) polecenie, np. `python3 train.py`\n",
    "   - `env` - pozwala zdefiniować zmienne środowiskowe dostępne dla akcji lub skorzystać ze [zmiennych ustawionych przez Github](https://docs.github.com/en/actions/reference/environment-variables#default-environment-variables)"
