Simplify Dogecoin setup to use Makefile targets

- Replace manual installation steps with make install-dogecoin
- Replace manual configuration with make dogecoin-config
- Remove raw dogecoin-cli commands in favor of make targets
- Keep documentation focused on what users need to do, not implementation details

 #### 1. Install Dogecoin Core
 ```bash
-# Download latest release (v1.14.6)
-wget https://github.com/dogecoin/dogecoin/releases/download/v1.14.6/dogecoin-1.14.6-x86_64-linux-gnu.tar.gz
-tar -xzf dogecoin-1.14.6-x86_64-linux-gnu.tar.gz
-sudo mv dogecoin-1.14.6/bin/* /usr/local/bin/
-
-# Or use Make command for automatic installation
+# Automatic installation with Make
 make install-dogecoin
 ```
 
+This command downloads and installs Dogecoin Core v1.14.6 to `/usr/local/bin`.
+
 #### 2. Configure Pruned Mode
-Create `~/.dogecoin/dogecoin.conf`:
-```ini
-# Enable server mode for RPC
-server=1
-daemon=1
-
-# RPC credentials - CHANGE THESE IN PRODUCTION!
-rpcuser=mps_doge_user
-rpcpassword=change_this_password_in_production
-rpcallowip=127.0.0.1
-rpcport=22555
-
-# PRUNED MODE - keeps only ~2GB instead of 50GB!
-prune=2000
-
-# Connect to reliable peers for faster sync
-addnode=seed.dogechain.info
-addnode=seed.multidoge.org
-addnode=seed.dogecoin.com
-
-# Hot wallet for Make Post Sell
-wallet=make_post_sell_hot_wallet
+```bash
+# Create configuration for pruned node
+make dogecoin-config
 ```
 
+This creates `~/.dogecoin/dogecoin.conf` with:
+- Pruned mode (2GB storage limit)
+- RPC server configuration
+- Reliable peer connections
+- Hot wallet setup
+
 #### 3. Start & Sync (Much Faster!)
 ```bash
-# Start dogecoin daemon (or use Make command)
-dogecoind
-# OR
+# Start dogecoin daemon
 make dogecoin-node
 
-# Initial sync takes ~2-4 hours (vs 12+ hours for full node)
-# Watch progress:
-dogecoin-cli getblockchaininfo
+# Monitor sync progress
 make dogecoin-status
-
-# When "blocks" equals "headers", sync is complete
 ```
 
+Initial sync takes ~2-4 hours for pruned mode. The status command shows:
+- Current block height vs total headers
+- Sync percentage
+- When blocks equal headers, sync is complete
+
 #### 4. Configure Make Post Sell
 ```ini
 # Enable Dogecoin payments
