+# How to use COLDCARD devices on Tails
+
+## Requirements
+
+- [Tails USB flash drive or SD card](../how-to-install-tails-on-usb-flash-drive-or-sd-card)
+- [COLDCARD](https://coldcard.com/) device
+
+## Caveats
+
+- When copy/pasting commands that start with `$`, strip out `$` as this character is not part of the command
+- When copy/pasting commands that start with `cat << "EOF"`, select all lines at once (from `cat << "EOF"` to `EOF` inclusively) as they are part of the same (single) command
+
+## Setup guide
+
+### Step 1: boot to Tails
+
+### Step 2: enable persistence (if not already enabled)
+
+Click “Applications”, then “Favorites”, then “Configure persistent volume”, set passphrase, click “Create”, make sure “Personal Data” is enabled, click “Save” and, finally, click “Restart Now”.
+
+### Step 3: boot to Tails, unlock persistent storage and set admin password (required to install dependencies and [ckcc](https://coldcard.com/docs/cli) and run coldcard.sh)
+
+> Heads-up: if keyboard layout of computer isn’t “English (US)”, set “Keyboard Layout”.
+
+Click “+” under “Additional Settings”, then “Administration Password”, set password, click “Add” and, finally, click “Start Tails”.
+
+### Step 4: install dependencies
+
+```console
+$ sudo apt update
+
+$ sudo apt install -y python3-pip python3-setuptools
+```
+
+### Step 5: install ckcc
+
+> Heads-up: ignore “Failed building wheel for pyaes” error (if present).
+
+```console
+$ torsocks pip3 install --user 'ckcc-protocol[cli]'
+```
+
+### Step 6: copy ckcc to persistent storage
+
+```console
+$ mkdir -p /home/amnesia/Persistent/.local
+
+$ cp -r /home/amnesia/.local/{bin,lib} /home/amnesia/Persistent/.local/
+```
+
+### Step 7: download [51-coinkite.rules](https://github.com/Coldcard/ckcc-protocol/blob/master/51-coinkite.rules)
+
+```console
+$ torsocks curl --output /home/amnesia/Persistent/51-coinkite.rules https://raw.githubusercontent.com/Coldcard/ckcc-protocol/master/51-coinkite.rules
+```
+
+### Step 8: create coldcard.sh script
+
+```console
+$ cat << "EOF" > /home/amnesia/Persistent/coldcard.sh
+#! /bin/bash
+
+set -e
+
+if [ "$(id -u)" -ne 0 ]; then
+  echo 'Please run as root'
+  exit
+fi
+
+sudo cp /home/amnesia/Persistent/51-coinkite.rules /etc/udev/rules.d/
+sudo -u amnesia cp -r /home/amnesia/Persistent/.local /home/amnesia/
+
+echo 'export PATH=$PATH:$HOME/.local/bin' >> /home/amnesia/.bashrc
+EOF
+
+$ chmod +x /home/amnesia/Persistent/coldcard.sh
+```
