+# OpenChallenges Data Lambda
+
+## Build the project
+
+```console
+nx build openchallenges-data-lambda
+```
+
+## Build the Docker image of the Lambda function
+
+```console
+nx build-image openchallenges-data-lambda
+```
+
+## Start the Lambda function locally with Docker Compose
+
+Starts the Lambda function in the foreground, allowing you to view logs and interact with it
+directly.
+
+```console
+nx serve openchallenges-data-lambda
+```
+
+Starts the Lambda function in detached mode, running it in the background. This is useful if you
+want to continue using the terminal for other tasks while the function runs.
+
+```console
+nx serve-detach openchallenges-data-lambda
+```
+
+## Invoke the Lambda function locally
+
+To invoke the Lambda function after starting it locally, use the following command:
+
+```console
+nx run openchallenges-data-lambda:invoke --event <path-to-json-file>
+```
+
+Replace `<path-to-json-file>` with the path to your JSON file containing the event payload relative
+to the location of the project folder. For example, if your event payload is stored in a file
+located at `events/event.json` relative to the project folder:
+
+```console
+nx run openchallenges-data-lambda:invoke --event events/event.json
+```
