+# RKI Covid Source
+
+This is the repository for the RkI (Robert Koch-Institut - von Marlon Lückert) Covid-19 source connector, written in Python.
+For information about how to use this connector within Airbyte, see [the documentation](https://docs.airbyte.io/integrations/sources/rki-covid).
+
+## Local development
+### Developed Streams (Endpoints)
+```
+Germany:
+    1. /germany
+    2. /germany/age-groups
+    3. /germany/history/cases/:days
+    4. /germany/history/incidence/:days
+    5. /germany/history/deaths/:days
+    6. /germany/history/recovered/:days
+    7. /germany/history/frozen-incidence/:days
+    8. /germany/history/hospitalization/:days
+```
+
+### Prerequisites
+**To iterate on this connector, make sure to complete this prerequisites section.**
+
+#### Minimum Python version required `= 3.7.0`
+
+#### Build & Activate Virtual Environment and install dependencies
+From this connector directory, create a virtual environment:
+```
+python -m venv .venv
+```
+
+This will generate a virtualenv for this module in `.venv/`. Make sure this venv is active in your
+development environment of choice. To activate it from the terminal, run:
+```
+source .venv/bin/activate
+pip install -r requirements.txt
+pip install '.[tests]'
+```
+If you are in an IDE, follow your IDE's instructions to activate the virtualenv.
+
+Note that while we are installing dependencies from `requirements.txt`, you should only edit `setup.py` for your dependencies. `requirements.txt` is
+used for editable installs (`pip install -e`) to pull in Python dependencies from the monorepo and will call `setup.py`.
+If this is mumbo jumbo to you, don't worry about it, just put your deps in `setup.py` but install using `pip install -r requirements.txt` and everything
+should work as you expect.
+
+#### Building via Gradle
+You can also build the connector in Gradle. This is typically used in CI and not needed for your development workflow.
+
+To build using Gradle, from the Airbyte repository root, run:
+```
+./gradlew :airbyte-integrations:connectors:source-rki-covid:build
+```
+
+#### Create credentials
+**If you are a community contributor**, follow the instructions in the [documentation](https://docs.airbyte.io/integrations/sources/rki-covid)
+to generate the necessary credentials. Then create a file `secrets/config.json` conforming to the `source_rki_covid/spec.json` file.
+Note that any directory named `secrets` is gitignored across the entire Airbyte repo, so there is no danger of accidentally checking in sensitive information.
+See `integration_tests/sample_config.json` for a sample config file.
+
+**If you are an Airbyte core member**, copy the credentials in Lastpass under the secret name `source rki-covid test creds`
+and place them into `secrets/config.json`.
+
+### Locally running the connector
+```
+python main.py spec
+python main.py check --config secrets/config.json
+python main.py discover --config secrets/config.json
+python main.py read --config secrets/config.json --catalog integration_tests/configured_catalog.json
+```
+
+### Locally running the connector docker image
+
+#### Build
+First, make sure you build the latest Docker image:
+```
+docker build . -t airbyte/source-rki-covid:dev
+```
+
+You can also build the connector image via Gradle:
+```
+./gradlew :airbyte-integrations:connectors:source-rki-covid:airbyteDocker
+```
+When building via Gradle, the docker image name and tag, respectively, are the values of the `io.airbyte.name` and `io.airbyte.version` `LABEL`s in
+the Dockerfile.
+
+#### Run
+Then run any of the connector commands as follows:
+```
+docker run --rm airbyte/source-rki-covid:dev spec
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-rki-covid:dev check --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-rki-covid:dev discover --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/source-rki-covid:dev read --config /secrets/config.json --catalog /integration_tests/configured_catalog.json
+```
+## Testing
+Make sure to familiarize yourself with [pytest test discovery](https://docs.pytest.org/en/latest/goodpractices.html#test-discovery) to know how your test files and methods should be named.
+First install test dependencies into your virtual environment:
+```
+pip install .[tests]
+```
+### Unit Tests
+To run unit tests locally, from the connector directory run:
+```
+python -m pytest unit_tests
+```
+
+### Integration Tests
+There are two types of integration tests: Acceptance Tests (Airbyte's test suite for all source connectors) and custom integration tests (which are specific to this connector).
+#### Custom Integration tests
+Place custom tests inside `integration_tests/` folder, then, from the connector root, run
+```
+python -m pytest integration_tests
+```
+#### Acceptance Tests
+Customize `acceptance-test-config.yml` file to configure tests. See [Source Acceptance Tests](https://docs.airbyte.io/connector-development/testing-connectors/source-acceptance-tests-reference) for more information.
+If your connector requires to create or destroy resources for use during acceptance tests create fixtures for it and place them inside integration_tests/acceptance.py.
+To run your integration tests with acceptance tests, from the connector root, run
+```
+python -m pytest integration_tests -p integration_tests.acceptance
+```
+To run your integration tests with docker
+
+### Using gradle to run tests
+All commands should be run from airbyte project root.
+To run unit tests:
+```
+./gradlew :airbyte-integrations:connectors:source-rki-covid:unitTest
+```
+To run acceptance and custom integration tests:
+```
+./gradlew :airbyte-integrations:connectors:source-rki-covid:integrationTest
+```
+
+## Dependency Management
+All of your dependencies should go in `setup.py`, NOT `requirements.txt`. The requirements file is only used to connect internal Airbyte dependencies in the monorepo for local development.
+We split dependencies between two groups, dependencies that are:
+* required for your connector to work need to go to `MAIN_REQUIREMENTS` list.
+* required for the testing need to go to `TEST_REQUIREMENTS` list
+
+### Publishing a new version of the connector
+You've checked out the repo, implemented a million dollar feature, and you're ready to share your changes with the world. Now what?
+1. Make sure your changes are passing unit and integration tests.
+1. Bump the connector version in `Dockerfile` -- just increment the value of the `LABEL io.airbyte.version` appropriately (we use [SemVer](https://semver.org/)).
+1. Create a Pull Request.
+1. Pat yourself on the back for being an awesome contributor.
+1. Someone from Airbyte will take a look at your PR and iterate with you to merge it into master.

+The (Robert Koch-Institut - von Marlon Lückert) Covid-19 is [a REST based API](https://api.corona-zahlen.org/). 
+Connector is implemented with [Airbyte CDK](https://docs.airbyte.io/connector-development/cdk-python).
+
+## Cases In Germany Covid api stream
+The basic entry stream is 'germany'. All other streams are extended version of base stream and passing parameters also result in sliced data.
+For production, every developer application can view multiple streams. 
+
+## Endpoints
+* [Provides covid cases and other information in Germany.](https://api.corona-zahlen.org/germany) \(Non-Incremental\ Entry-Stream)
+* [Provides covid cases and other information in Germany, group by age.](https://api.corona-zahlen.org/germany/age-groups) \(Non-Incremental\)
+* [Provides cases in Germany based on days.](https://api.corona-zahlen.org/germany/germany/history/cases/:days) \(Incremental\)
+* [Provides incidence rate of covid in Germany based on days.](https://api.corona-zahlen.org/germany/germany/history/incidence/:days) \(Incremental\)
+* [Provides death rate in Germany over days](https://api.corona-zahlen.org/germany/germany/history/deaths/:days) \(Incremental\)
+* [Provides recovery rate in Germany over days.](https://api.corona-zahlen.org/germany/germany/history/recovered/:days) \(Incremental\)
+* [Provides frozen incidence in Germany over days.](https://api.corona-zahlen.org/germany/germany/history/frozen-incidence/:days) \(Incremental\)
+* [Provides hospitalization rate in Germany over days.](https://api.corona-zahlen.org/germany/germany/history/hospitalization/:days) \(Incremental\)
+
+
+
+Incremental streams have required parameter start-date. Without passing start-date as parameter full-refresh occurs.
+As cursor field this connector uses "date".
