-### Import sample metadata projects
+### Export database to json file
+
+To export data of certain models from database to json file.
+
+`npm run data:export -- --file path/to-file.json`
+
+List of models that will be exported is defined in `scripts/data/dataModels.js`. You can add new models to this list,
+but make sure that new models are added to list such that each model comes after its dependencies.
+
+When we run `npm run data:export` without specifying json file , data will be exported to `data/demo-data.json`.
+
+### Import database from json file, and index it
+
+To import data of certain models from file to database, and create ES indices.
+
+`npm run data:import -- --file path/to-file.json`
+
+List of models that will be imported is defined in `scripts/data/dataModels.js`. You can add new models to this list,
+but make sure that new models are added to list such that each model comes after its dependencies.
+
+When we run `npm run data:import` without specifying json file , data will be imported from `data/demo-data.json`.
+There is sample file located at `data/demo-data.json` that can used to import and index sample data.
+
+Because this commands calls topcoder services to get data like members details, so you have to set environment variables AUTH0_CLIENT_ID, AUTH0_CLIENT_SECRET, AUTH0_URL, AUTH0_AUDIENCE, AUTH0_PROXY_SERVER_URL
+
+If you encounter conflicts errors, you may need to clear database using `npm run sync:db`, and clear ES (Elasticsearch) indices using `NODE_ENV=development npm run sync:es`
