 Biscuit used to build on Linux and OpenBSD, but probably only builds on Linux
 currently. You must build Biscuit's modified Go runtime before building
 Biscuit:
+
 ```
 $ git clone https://github.com/mit-pdos/biscuit.git
 $ cd biscuit/src
 $ ./make.bash
 ```
 
 then go to Biscuit's main part and launch it:
+
 ```
 $ cd ../biscuit
 $ make qemu CPUS=2
 ```
 
 Biscuit should boot, then you can type a command:
+
+```
+# ls
+```
+
+## Build with Docker
+
+Don't you have Linux installed on your computer? No worries, you can build the project and run it using docker. You only need to have Docker installed, and run the commands:
+
+```
+docker build -t biscuit .
+docker run -it biscuit
+```
+
+Biscuit should boot, then you can type a command:

 ```
 # ls
