+# Tezos RPC client
+
+The library realize almost all RPC methods of Tezos node.
+
+## Usage
+
+### Simple example
+
+```go
+rpc := node.NewRPC("https://rpc.tzkt.io/mainnet", "main")
+ctx, cancel := context.WithTimeout(context.Background(), time.Second*10)
+defer cancel()
+
+block, err := rpc.Block(ctx, "head")
+if err != nil {
+	panic(err)
+}
+log.Printf("%##v", block)
+```
+
+You can use main RPC constructor where chain id set by default to `main`
+
+```go
+rpc := node.NewMainRPC("https://rpc.tzkt.io/mainnet")
+```
+
+### Usage certain API part
+
+RPC struct contains some internal parts: `Chain`, `Block`, `Context`, `Config`, `General`, `Protocols`, `Inject` and `Network`. You can use it without creation of full RPC client.
+
+```go
+rpc := node.NewMainBlockRPC("https://rpc.tzkt.io/mainnet")
+ctx, cancel := context.WithTimeout(context.Background(), time.Second*10)
+defer cancel()
+
+block, err := rpc.Block(ctx, "head")
+if err != nil {
+	panic(err)
+}
+log.Printf("%##v", block)
+```
+
+### Interfaces
+
+For testing purpose RPC was wrapped by interfaces. Also each part of RPC has interface. You can mock it with code generation tools.
+
+Interfaces list:
+* `BlockAPI`
+* `ChainAPI`
+* `ContextAPI`
+* `ConfigAPI`
+* `GeneralAPI`
+* `ProtocolsAPI`
+* `NetworkAPI`
+* `InjectAPI`
