+TREZOR Firmware
+===============
+
+[![Build Status](https://travis-ci.org/trezor/trezor-mcu.svg?branch=master)](https://travis-ci.org/trezor/trezor-mcu)
+
+http://bitcointrezor.com/
+
+How to build TREZOR firmware?
+-----------------------------
+
+1. Install Docker (from docker.com or from your distribution repositories)
+2. `git clone https://github.com/trezor/trezor-mcu.git`
+3. `cd trezor-mcu`
+4. `./firmware-docker-build.sh TAG` (where TAG is v1.3.2 for example, if left blank the script builds latest commit)
+
+This creates file `output/trezor-TAG.bin` and prints its fingerprint at the last line of the build log.
+
+How to get fingerprint of firmware signed and distributed by SatoshiLabs?
+-------------------------------------------------------------------------
+
+1. Pick version of firmware binary listed on https://mytrezor.com/data/firmware/releases.json
+2. Download it: `wget -O trezor.signed.bin.hex https://mytrezor.com/data/firmware/trezor-1.1.0.bin.hex`
+3. `xxd -r -p trezor.signed.bin.hex trezor.signed.bin`
+4. `./firmware-fingerprint.sh trezor.signed.bin`
+
+Step 4 should produce the same sha256 fingerprint like your local build (for the same version tag).
+
+The reasoning for `firmware-fingerprint.sh` script is that signed firmware has special header holding signatures themselves, which must be avoided while calculating the fingerprint.
