+# CRE Generated Bindings (MVP)
+
+This project utilizes a forked version of `abigen` (from go-ethereum)
+that lets you generate Go bindings for your smart contracts using a custom template.
+
+## Prerequisites
+
+1. **Go**
+   Install Go 1.18 or later:
+   ```bash
+   brew install go          # macOS (Homebrew)
+   sudo apt install golang  # Ubuntu/Debian
+   ```
+2. **Solidity compiler**
+   Install `solc` to compile or verify your contracts:
+   ```bash
+   npm install -g solc      # via npm
+   brew install solidity    # macOS (Homebrew)
+   ```
+
+## Usage
+### Programmatic API
+
+```go
+import "github.com/smartcontractkit/cre-cli/cmd/generate-bindings/bindings"
+
+func main() {
+  err := bindings.GenerateBindings(
+    "./pkg/bindings/build/MyContract_combined.json", // or "" if using abiPath
+    "./pkg/bindings/MyContract.abi",                 // or "" for combined-json mode
+    "bindings",                                       // Go package name
+    "MyContract",                                     // typeName (single-ABI only)
+    "./pkg/bindings/build/bindings.go",               // output file
+  )
+  if err != nil {
+    log.Fatalf("generate bindings: %v", err)
+  }
+}
+```
