These are the steps I ran to configure https://github.com/RichardAtCT/claude-code-telegram/tree/main on a DO droplet

setup.sh

sudo apt update

# install zsh
sudo apt install zsh -y

# install other essentials
sudo apt install build-essential procps curl file git -y

# install gh
sudo apt install gh

# install oh-my-zsh
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

# for poetry
sudo apt install -y curl python3-venv python3-pip

# github
ssh-keygen -t ed25519 -C "do-droplet-deploy-key" -f ~/.ssh/github_deploy_key
cat ~/.ssh/github_deploy_key.pub # add to Github SSH keys

cat >> ~/.ssh/config <<'EOF'
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/github_deploy_key
  IdentitiesOnly yes
EOF

chmod 600 ~/.ssh/config

ssh-keyscan -H github.com >> ~/.ssh/known_hosts
chmod 644 ~/.ssh/known_hosts

# install poetry
curl -sSL https://install.python-poetry.org | python3 -

echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# install claude code
curl -fsSL https://claude.ai/install.sh | bash

nano ~/.zshrc
export ANTHROPIC_API_KEY="sk-..."
source ~/.zshrc

# install the bot

git clone https://github.com/RichardAtCT/claude-code-telegram.git
cd claude-code-telegram
make dev

# Telegram
# Open app and get a bot token from @BotFather
# /newbot - go through the process

mkdir /root/projects
cp .env.example
nano .env

```
