# This workflow creates releases without requiring a PAT token
# Version updates are included in the tag commit but NOT pushed back to the branch
# This allows it to work with protected branches that require PRs
#
# To update VERSION and build.zig.zon on master, manually create a PR after release

          ```zig
          const zigeth = @import("zigeth");
          
          // Create a wallet
          var wallet = try zigeth.signer.Wallet.generate(allocator);
          
          // Connect to Ethereum
          var provider = try zigeth.providers.Networks.mainnet(allocator);
          defer provider.deinit();
          
          // Get balance
          const balance = try provider.getBalance(address);
          ```
          
          ## 📥 Installation
