+## Download Binaries and Docker Images
+
+The [`scripts/bootstrap.sh`](https://github.com/hyperledger/fabric-samples/blob/release-1.1/scripts/bootstrap.sh)
+script will preload all of the requisite docker
+images for Hyperledger Fabric and tag them with the 'latest' tag. Optionally,
+specify a version for fabric, fabric-ca and thirdparty images. Default versions
+are 1.1.0, 1.1.0 and 0.4.7 respectively.
+
+```bash
+./scripts/bootstrap.sh [version] [ca version] [thirdparty_version]
+```
