 xBrowserSync is a free tool for syncing browser data between different browsers and devices, built for privacy and anonymity. For full details, see [www.xbrowsersync.org](https://www.xbrowsersync.org/).

 Running the API image alone requires that you have a MongoDB instance and, ideally, a web server to reverse proxy the API behind.

Create a file named `settings.json` and include any required custom [settings](https://github.com/xbrowsersync/api#3-modify-configuration-settings) values, such as those for connecting to your MongoDB instance. For example, if you are running docker and MongoDB on a windows server, you would point the service at the MongoDB instance running on the host using the following settings:

   3. Run the following command to start an API container, providing the actual path to the `settings.json` file created in step 1. The service will be exposed via port 8080. If you did not create the environment variables in step 2, you will need to provide the actual username and password values in line, i.e. `-e XBROWSERSYNC_DB_USER=YourDatabaseUsername -e XBROWSERSYNC_DB_PWD=YourDatabasePassword`:
 
       ```
-      sudo docker run --name xbs-api -p 8080:8080 -e XBROWSERSYNC_DB_USER -e XBROWSERSYNC_DB_PWD -v /path/to/settings.json:/usr/src/api/config/settings.json -d xbrowsersync/api

+## Running a production-ready service
 
 If you do not already have a MongoDB instance or are intending to expose your xBrowserSync service over the internet then it is recommended to use the provided [`docker-compose.yml`](https://github.com/xbrowsersync/api-docker/blob/master/docker-compose.yml) which will create fully configured containers for a MongoDB database, the xBrowserSync API and a [traefik](https://traefik.io/) reverse proxy web server to run in front of the API. Traefik automatically acquires and updates SSL certificates from [Let's Encrypt](https://letsencrypt.org/) so that your xBrowserSync API service will run securely over HTTPS.

   2. Secure the [`acme.json`](https://github.com/xbrowsersync/api-docker/blob/master/acme.json) file as per traefik's requirements:

-      sudo chmod 600 acme.json

       ```
 
   3. Open the [`.env`](https://github.com/xbrowsersync/api-docker/blob/master/.env) file in a text editor and update the `XBS_API_HOSTNAME` value to correspond to the host name that the API service will be exposed over (ensure you have configured your DNS provider to point the desired host name to your host's IP address). Also, change the `XBS_DB_USERNAME` and `XBS_DB_PASSWORD` values to any of your choosing.
