+# Google Tasks
+This directory contains the manifest-only connector for `source-google-tasks`.
+
+## Documentation reference:
+Visit `https://developers.google.com/tasks/reference/rest` for API documentation
+
+## Authentication setup
+`Source-productive` uses bearer token authentication,
+Visit `https://support.google.com/googleapi/answer/6158849?hl=en&ref_topic=7013279` for getting bearer token via OAuth2.0
+
+## Setting postman for getting bearer token
+Currently Code granted OAuth 2.0 is not directly supported by airbyte, thus you could setup postman for getting the bearer token which could be used as `api_key`,
+Steps:
+- Visit google cloud `https://console.cloud.google.com/apis/api/tasks.googleapis.com/metrics` and enable the tasks api service
+- Go to the consent screen `https://console.cloud.google.com/apis/credentials/consent` and add your email for enabling postman testing access
+- Visit `https://console.cloud.google.com/apis/credentials` and create new credentails for OAuth 2.0 and copy client id and client secret 
+- Add callback url `https://oauth.pstmn.io/v1/callback` while credential creation
+- Goto postman client and select new tab for setting authorization to OAuth 2.0
+  - Set scope as `https://www.googleapis.com/auth/tasks https://www.googleapis.com/auth/tasks.readonly`
+  - Set access token URL as `https://accounts.google.com/o/oauth2/token`
+  - Set auth URL as `https://accounts.google.com/o/oauth2/v2/auth`
+  - Click `Get New Access Token` and authorize via your google account
+  - Copy the resulted bearer token and use it as credential for the connector
+
+## Usage
+There are multiple ways to use this connector:
+- You can use this connector as any other connector in Airbyte Marketplace.
+- You can load this connector in `pyairbyte` using `get_source`!
+- You can open this connector in Connector Builder, edit it, and publish to your workspaces.
+
+Please refer to the manifest-only connector documentation for more details.
+
+## Local Development
+We recommend you use the Connector Builder to edit this connector.
+
+But, if you want to develop this connector locally, you can use the following steps.
+
+### Environment Setup
+You will need `airbyte-ci` installed. You can find the documentation [here](airbyte-ci).
+
+### Build
+This will create a dev image (`source-google-tasks:dev`) that you can use to test the connector locally.
+```bash
+airbyte-ci connectors --name=source-google-tasks build
+```
+
+### Test
+This will run the acceptance tests for the connector.
+```bash
+airbyte-ci connectors --name=source-google-tasks test
+```
+
