+# Docker Swarm Usage
+
+## Healthcheck
+
+The [Docker Image](../Dockerfile) includes a Healthcheck with the following options:
+
+```
+--interval=30s
+```
+> Specifies the time interval at which the health check should be performed. In this case, the health check will be performed every 30 seconds.
+
+<br>
+
+```
+--timeout=10s
+```
+> Specifies the amount of time to wait for a response from the health check command. If the response does not arrive within 10 seconds, the health check will be considered a failure.
+
+<br>
+
+```
+--start-period=5s
+```
+> Specifies the amount of time to wait before starting the health check process. In this case, the health check process will begin 5 seconds after the container is started.
+
+<br>
+
+```
+--retries=3
+```
+> Specifies the number of times Docker should retry the health check before considering the container to be unhealthy.
+
+<br>
+
+
+The CMD instruction is used to define the command that will be run as part of the health check. 
+In this case, the command is `wget --quiet --tries=1 --spider http://localhost:3000/ || exit 1`. This command will attempt to connect to `http://localhost:3000/` 
+and if it fails it will exit with a status code of `1`. If this command returns a status code other than `0`, the health check will be considered a failure.
+
+Overall, this HEALTHCHECK instruction is defining a health check process that will run every 30 seconds, wait up to 10 seconds for a response, 
+begin 5 seconds after the container is started, and retry up to 3 times. 
+The health check will consist of attempting to connect to http://localhost:3000/ and will consider the container to be unhealthy if it is unable to connect.

-### What about security? Are my files encrypted while being sent between the computers?
 Yes. Your files are sent using WebRTC, which encrypts them on transit. To ensure the connection is secure and there is no MITM, compare the security number shown under the device name on both devices. The security number is different for every connection.

-### Transferring many files with paired devices takes too long

 Snapdrop and PairDrop are a study in radical simplicity. The user interface is insanely simple. Features are chosen very carefully because complexity grows quadratically since every feature potentially interferes with each other feature. We focus very narrowly on a single use case: instant file transfer. 
 We are not trying to optimize for some edge-cases. We are optimizing the user flow of the average users. Don't be sad if we decline your feature request for the sake of simplicity.
