-This is the repository for the MeiliSearch destination connector, written in Java.
+This is the repository for the Meilisearch destination connector, written in Python.
+For information about how to use this connector within Airbyte, see [the documentation](https://docs.airbyte.io/integrations/destinations/meilisearch).
 
 ## Local development
 
 ### Prerequisites
 **To iterate on this connector, make sure to complete this prerequisites section.**
 
-#### Build & Activate Virtual Environment
-First, build the module by running the following from the `airbyte` project root directory: 
+#### 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
+```
+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
+From the Airbyte repository root, run:
 ```
 ./gradlew :airbyte-integrations:connectors:destination-meilisearch:build
 ```
 
 #### Create credentials
-If you are running MeiliSearch locally you may not need an api key at all. If there is an API key set for MeiliSearch, you can find instruction on how to find it in the [MeiliSearch docs](https://docs.meilisearch.com/reference/features/authentication.html#master-key).
+**If you are a community contributor**, follow the instructions in the [documentation](https://docs.airbyte.io/integrations/destinations/meilisearch)
+to generate the necessary credentials. Then create a file `secrets/config.json` conforming to the `destination_meilisearch/spec.json` file.
+Note that the `secrets` directory is gitignored by default, 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**, the integration tests do not require any external credentials. MeiliSearch is run from a test container.
+**If you are an Airbyte core member**, copy the credentials in Lastpass under the secret name `destination meilisearch 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/destination-meilisearch:dev
+```
+
+You can also build the connector image via Gradle:
 ```
-# in airbyte root directory
 ./gradlew :airbyte-integrations:connectors:destination-meilisearch: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/destination-meilisearch:dev spec
-docker run --rm -v $(pwd)/airbyte-integrations/connectors/destination-meilisearch/secrets:/secrets airbyte/destination-meilisearch:dev check --config /secrets/config.json
-docker run --rm -v $(pwd)/airbyte-integrations/connectors/destination-meilisearch/secrets:/secrets airbyte/destination-meilisearch:dev discover --config /secrets/config.json
-docker run --rm -v $(pwd)/airbyte-integrations/connectors/destination-meilisearch/secrets:/secrets -v $(pwd)/airbyte-integrations/connectors/destination-meilisearch/sample_files:/sample_files airbyte/destination-meilisearch:dev read --config /secrets/config.json --catalog /sample_files/configured_catalog.json
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/destination-meilisearch:dev check --config /secrets/config.json
+# messages.jsonl is a file containing line-separated JSON representing AirbyteMessages
+cat messages.jsonl | docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/destination-meilisearch:dev write --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
-1. From the airbyte project root, run `./gradlew :airbyte-integrations:connectors:destination-meilisearch:integrationTest` to run the standard integration test suite.
+There are two types of integration tests: Acceptance Tests (Airbyte's test suite for all destination 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
+Coming soon: 
+
+### Using gradle to run tests
+All commands should be run from airbyte project root.
+To run unit tests:
+```
+./gradlew :airbyte-integrations:connectors:destination-meilisearch:unitTest
+```
+To run acceptance and custom integration tests:
+```
+./gradlew :airbyte-integrations:connectors:destination-meilisearch: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.
