# IC-OS Verification

To build and verify the IC-OS disk image, run:

```
# From https://github.com/dfinity/ic#building-the-code
# This process requires Mac/Linux/WSL2, Git and Podman on your machine.
git clone https://github.com/dfinity/ic
cd ic
git fetch origin
git checkout 935b417d6f5dd2befa7f9ad7bfc975df32f8c641

# The two SHA256 sums above from a) the downloaded CDN image and b) the locally built image,
# must be identical, and must match the SHA256 from the payload of the NNS proposal.
