```
1. Find the latest stable version of Nethermind on Github
  - Find latest Nethermind version at https://github.com/NethermindEth/nethermind/releases
  - Write latest stable Nethermind version in format such as 1.31.9-98c5dca4:
2. Download Nethermind version 1.31.9-98c5dca4 to your node
```
cd ~/downloads && curl -LO https://github.com/NethermindEth/nethermind/releases/download/1.31.9/nethermind-1.31.9-98c5dca4-linux-x64.zip
```
3. Unzip the downloaded file
```
unzip nethermind-1.31.9-98c5dca4-linux-x64 -d nethermind
```
4. Stop running clients
  $ journalctl -fu nethermind
  
  $ sudo systemctl stop nethermind && systemctl status nethermind
  
  /usr/local/bin/staking.sh monitor execution
  
  /usr/local/bin/staking.sh stop execution && /usr/local/bin/staking.sh check execution
5. Remove the old client
```
sudo rm -r /usr/local/bin/nethermind
```
6. Copy the client to /usr/local/bin/
```
sudo cp -a nethermind /usr/local/bin/nethermind
```
7. Start the client again
  $ sudo systemctl start nethermind && systemctl status nethermind
  
  $ journalctl -fu nethermind
  
  /usr/local/bin/staking.sh start execution && /usr/local/bin/staking.sh check execution
  
  /usr/local/bin/staking.sh monitor execution

3. Verify hash of donwnloaded file
  Get hash of downloaded file and compare it with official hashes
```
sha256sum erigon_v3.0.2_linux_amd64v2.tar.gz
```
  And check it compare to the provided hash for the file from https://github.com/erigontech/erigon/releases/download/v3.0.2/erigon_v3.0.2_checksums.txt (Note: The link links at 3.0.2 version )
4. Extract the downloaded package
```
tar xvf erigon_v3.0.2_linux_amd64v2.tar.gz
```
5. Stop Erigon client
  Note: It's a good practice to check the log before stopping the client. journalctl -fu erigon
  
  sudo systemctl stop erigon && systemctl status erigon
  
  Note: It's a good practice to check the log before stopping the client. /usr/local/bin/staking.sh monitor execution
