 ## Installation and Usage
 
+### Build with Docker (recommended)
+
+Assuming you have Docker installed and running, you can serve binhop locally with something like:
+
+```
+git clone https://github.com/darrylnixon/binhop.git
+cd binhop
+docker build . -t csc842/binhop
+docker run --name binhop -e PORT=3050 -p 3050:3050 --restart=always csc842/binhop
+```
+
+Then browse to [http://localhost:3050](http://localhost:3050) and upload a blob.
+
+### Manually
+
 To use this script, you need Python 3 and a functioning and "recent" version of `binwalk` installed on your system. In practice, this means you're *probably* going to need to be on an x86/x86_64 Linux, but maybe you have better karma than I do.
 
 You'll probably also want to install optional `binwalk` dependencies such as `sasquatch`, `jefferson`, and others, depending on the binaries you want to submit. You can learn how to do that in [binwalk's INSTALL.md](https://github.com/ReFirmLabs/binwalk/blob/master/INSTALL.md). `binhop` only "requires" `binwalk`, but it'll fail on binaries for which `binwalk` is dependent on optional modules.
