```sh
# Download and install binary
cd $HOME
rm -rf c4e-chain/
git clone https://github.com/chain4energy/c4e-chain.git
cd c4e-chain/
git checkout v1.2.1
make build


# Setup Cosmovisor Symlinks
mkdir -p $HOME/.c4e-chain/cosmovisor/genesis/bin
mv build/c4ed $HOME/.c4e-chain/cosmovisor/genesis/bin/
rm -rf build

sudo ln -s $HOME/.c4e-chain/cosmovisor/genesis $HOME/.c4e-chain/cosmovisor/current
sudo ln -s $HOME/.c4e-chain/cosmovisor/current/bin/c4ed /usr/local/bin/c4ed


# Set Configuration for your node
c4ed config chain-id perun-1
c4ed config keyring-backend file


# Init your node
# You can change "MyNode" to anything you like
c4ed init MyNode --chain-id perun-1


# Add Genesis File and Addrbook
wget https://raw.githubusercontent.com/chain4energy/c4e-chains/main/perun-1/genesis.json -O $HOME/.c4e-chain/config/genesis.json

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.indonode.net/mainnet/c4e/installation.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
