+Once started, the replay system's web interface can be accessed through a web browser, e.g., <http://localhost:2016/> by default.
 
-To run it under a domain name other than `localhost`, the easiest approach is to use a reverse proxy that supports HTTPS. The replay system utilizes [Service Worker](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) for URL rerouting/rewriting to prevent [live leakage (zombies)](http://ws-dl.blogspot.com/2012/10/2012-10-10-zombies-in-archives.html). However, for security reason many web browsers have mandated HTTPS for the Service Worker API with only exception if the domain is `localhost`. [Caddy Server](https://caddyserver.com/) and [Traefik](https://traefik.io/) can be used as a reverse-proxy server and are very easy to setup. They come with built-in HTTPS support and manage (install and update) TLS certificates transparently and automatically from [Let's Encrypt](https://letsencrypt.org/). However, any web server proxy that has HTTPS support on the front-end will work. To make ipwb replay aware of the proxy, use `--proxy` or `-P` flag to supply the proxy URL. This way the replay will yield the supplied proxy URL as a prefix when generating various fully qualified domain name (FQDN) URIs or absolute URIs (for example, those in the TimeMap or Link header) instead of the default `http://localhost:5000`. This can be necessary when the service is running in a private network or a container and only exposed via a reverse-proxy. Suppose a reverse-proxy server is running and ready to forward all traffic on the `https://ipwb.example.com` to the ipwb replay server then the replay can be started as following:

+The container will run an IPFS daemon, index a sample WARC file, and replay it using the newly created index. It will take a few seconds to be ready, then the replay will be accessible at <http://localhost:2016/> with a sample archived page.
 
 To index and replay your own WARC file, bind mount your data folders inside the container using `-v` (or `--volume`) flag and run commands accordingly. The provided docker image has designated `/data` directory, inside which there are `warc`, `cdxj`, and `ipfs` folders where host folders can be mounted separately or as a single mount point at the parent `/data` directory. Assuming that the host machine has a `/path/to/data` folder under which there are `warc`, `cdxj`, and `ipfs` folders and a WARC file at `/path/to/data/warc/custom.warc.gz`.
 
 ```
 $ docker container run -it --rm -v /path/to/data:/data oduwsdl/ipwb ipwb index -o /data/cdxj/custom.cdxj /data/warc/custom.warc.gz

+$ docker container run -it --rm -v /path/to/data:/data -p 2016:2016 oduwsdl/ipwb ipwb replay /data/cdxj/custom.cdxj
 ```
 
 If the host folder structure is something other than `/some/path/{warc,cdxj,ipfs}` then these volumes need to be mounted separately.
