-The official DeFiChain AppImage release of the Defi Wallet for Linux will not work for the Raspberrys. So I have made for myself a compiled version of the Defi Wallet for my Raspberry Pi 4B 4GB with official Raspberry Pi OS (32-Bit). This so called `armv7l` version is different to other Linux `x86_64` distributions as well as different to the Raspberry Pi 64-Bit version `arm8` respective `arm64`. 
+The official DeFiChain AppImage release of the Defi Wallet for Linux will not work for the Raspberrys. So I have made for myself a compiled version of the Defi Wallet for my Raspberry Pi 4B 8GB with official Raspberry Pi OS (64-Bit). This so called `arm8`, `arm64` respective `aarch64` version is different to other Linux `x86_64` distributions.  
 
 The compiled Raspberry Pi AppImage bases on the DeFiChain original source code. No code was modyfied and was ~100% taken from the DeFiChain repository - ok, the npm workspace file package.json includes now the build for the arm-processors😉
 
-> Note: I compiled the node and wallet on my Raspberry Pi with Raspberry OS bullseye (Debian v11). I got the feedback that you therefore have to upgrade your Raspberry to the same version as mine.
