+Often when you're looking into a website, there's several things you always initially check.
+Think: Whois, SSL chain, DNS records, tech stack, security protocols, crawl rules, sitemap, redirects, basic performance, open ports, server info, etc.
+None of this is hard to find with a series of basic curl commands, or a combination of online tools. But it's just so much easier to have everything presented clearly and visible in one place :)

+
+### Deploying - Option #1: Netlify
 
 Click the button below, to deploy to Netlify 👇
 
 [![Deploy to Netlify](https://img.shields.io/badge/Deploy-Netlify-%2330c8c9?style=for-the-badge&logo=netlify&labelColor=1e0e41 'Deploy Web-Check to Netlify, via 1-Click Script')](https://app.netlify.com/start/deploy?repository=https://github.com/lissy93/web-check)
 
+### Deploying - Option #2: Docker
+
+Run `docker run -p 8888:3000 lissy93/web-check`, then open `http://localhost:3000`
+
+The app is published to DockerHub ([`hub.docker.com/r/lissy93/web-check`](https://hub.docker.com/r/lissy93/web-check)) as well as GHCR ([`ghcr.io/lissy93/web-check`](https://github.com/Lissy93/web-check/pkgs/container/web-check)), or you can build the image yourself by cloning the project and running `docker build -t web-check .`

+
+### Deploying - Option #3: From Source
+
+Follow the instructions in the [Developing](#developing) section above, then run `yarn build` && `yarn start` to build and serve the application.
+
+### Configuring
+By default, no configuration is needed, but there are some optional environmental variables that you can set to give you access to some additional checks. These include:
+
+- `GOOGLE_CLOUD_API_KEY` - A Google API key ([get here](https://cloud.google.com/api-gateway/docs/authenticate-api-keys)). This can be used to return quality metrics for a site
+- `TORRENT_IP_API_KEY` - A torrent API key ([get here](https://iknowwhatyoudownload.com/en/api/)). This will show torrents downloaded by an IP
+- `REACT_APP_SHODAN_API_KEY` - A Shodan API key ([get here](https://account.shodan.io/)). This will show associated host names for a given domain
+- `REACT_APP_WHO_API_KEY` - A WhoAPI key ([get here](https://whoapi.com/)). This will show more comprehensive WhoIs records than the default job
+- `SECURITY_TRAILS_API_KEY` - A Security Trails API key ([get here](https://securitytrails.com/corp/api)). This will show org info associated with the IP
+- `BUILT_WITH_API_KEY` - A BuiltWith API key ([get here](https://api.builtwith.com/)). This will show the main features of a site
+
+The above keys can be added into an `.env` file in the projects root, or via the Netlify UI, or by passing directly to the Docker container.
