+<https://github.com/distrust-foundation/airgap>

 ## About ##

-A full-source-bootstrapped, deterministic, minimal, immutable, and offline,
-workstation linux distribution designed for creating and managing secrets
-offline.
+A live buildroot based Liux distribution designed for managing secrets offline.

 Built for those of us that want to be -really- sure our most important secrets
 are managed in a clean environment with an "air gap" between us and the
 internet with high integrity on the supply chain of the firmware and OS used.

 ## Uses ##
- * Generate PGP keychain
+ * Generate GPG keychain
 * Store/Restore gpg keychain to security token such as a Yubikey or Nitrokey
 * Signing cryptocurrency transactions
 * Generate/backup BIP39 universal cryptocurrency wallet seed
 * Store/Restore BIP39 seed to a hardware wallet such as a Trezor or Ledger

 ## Features ##
- * Deterministic iso generation for multi-party code->binary verification
+ * Determinsitic iso generation for multi-party code->binary verification
 * Small footprint (< 100MB)
 * Immutable and Diskless: runs from initramfs
 * Network support and most drivers removed to minimize exfiltration vectors
@ -29,54 +27,37 @@ internet with high integrity on the supply chain of the firmware and OS used.

 ### Software ###

-* docker 26+
+* docker 18+

 ### Hardware ###

-* x86_64 PC or laptop
-    * linuxboot/heads firmware supported and recommended for multi-use machine
-      * Allows for signed builds, and verification of signed sd card payloads
-    * Ensure any Wifi/Disk/Bluetooth/Audio devices are disabled/removed
+* Recommended: PC running coreboot-heads
+  * Allows for signed builds, and verification of signed sd card payloads
+  * Ensure any Wifi/Disk/Bluetooth/Audio devices are disabled/removed
+* Supported remote attestation key (Librem Key, Nitrokey, etc)
+* Supported GPG smartcard device (Yubikey, Ledger, Trezor, Librem Key, etc)
 * Blank flash drive
 * Blank SD card

 ## Build ##

-### Update git submodules
-
-```
-git submodule update --init --recursive
-```
-
 ### Build a new release

-```
-make release
-```
+    ```
+    make release
+    ```

 ### Reproduce an existing release

-```
-make attest
-```
+    ```
+    make attest
+    ```

 ### Sign an existing release

-```
-make sign
-```
-
-## Provisioning ##
-
-1. Write airgap.iso to CD-ROM or SD Card
-  a. `dd if=out/airgap.iso of=/dev/sda bs=1M conv=sync status=progress`
-  b. `cdrecord out/airgap.iso`
-
-2. Verify media still produces expected hash
-  ```
-  sha256sum out/airgap.iso
-  head -c $(stat -c '%s' airgap.iso) /dev/sda | sha256sum
-  ```
+    ```
+    make sign
+    ```
