+# Go client
+
+The OpenSearch Go client lets you connect your Go application with the data in your OpenSearch cluster.
+
+
+## Setup
+
+If you're creating a new project:
+
+```go
+go mod init
+```
+
+To add the client to your project, import it like any other module:
+
+```go
+go get github.com/opensearch-project/opensearch-go
+```
+
+## Sample code
+
+This sample code creates a client, adds an index with non-default settings, inserts a document, searches for the document, deletes the document, and finally deletes the index:
+
+```go
+package main
+import (
+    "os"
+    "context"
+    "crypto/tls"
+    "fmt"
+    opensearch "github.com/opensearch-project/opensearch-go"
+    opensearchapi "github.com/opensearch-project/opensearch-go/opensearchapi"
+    "net/http"
+    "strings"
+)
+const IndexName = "go-test-index1"
+func main() {
+    // Initialize the client with SSL/TLS enabled.
+    client, err := opensearch.NewClient(opensearch.Config{
+        Transport: &http.Transport{
+            TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
+        },
+        Addresses: []string{"https://localhost:9200"},
+        Username:  "admin", // For testing only. Don't store credentials in code.
+        Password:  "admin",
+    })
+    if err != nil {
+        fmt.Println("cannot initialize", err)
+        os.Exit(1)
+    }
+
+    // Print OpenSearch version information on console.
+    fmt.Println(client.Info())
+
+    // Define index mapping.
+    mapping := strings.NewReader(`{
+     'settings': {
+       'index': {
+            'number_of_shards': 4
+            }
+          }
+     }`)
+
+    // Create an index with non-default settings.
+    res := opensearchapi.CreateRequest{
+        Index: IndexName,
+        Body:  mapping,
+    }
+    fmt.Println("creating index", res)
+
+    // Add a document to the index.
+    document := strings.NewReader(`{
+        "title": "Moneyball",
+        "director": "Bennett Miller",
+        "year": "2011"
+    }`)
+
+    docId := "1"
+    req := opensearchapi.IndexRequest{
+        Index:      IndexName,
+        DocumentID: docId,
+        Body:       document,
+    }
+    insertResponse, err := req.Do(context.Background(), client)
+    if err != nil {
+        fmt.Println("failed to insert document ", err)
+        os.Exit(1)
+    }
+    fmt.Println(insertResponse)
+
+    // Search for the document.
+    content := strings.NewReader(`{
+       "size": 5,
+       "query": {
+           "multi_match": {
+           "query": "miller",
+           "fields": ["title^2", "director"]
+           }
+      }
+    }`)
+
+    search := opensearchapi.SearchRequest{
+        Body: content,
+    }
+
+    searchResponse, err := search.Do(context.Background(), client)
+    if err != nil {
+        fmt.Println("failed to search document ", err)
+        os.Exit(1)
+    }
+    fmt.Println(searchResponse)
+
+    // Delete the document.
+    delete := opensearchapi.DeleteRequest{
+        Index:      IndexName,
+        DocumentID: docId,
+    }
+
+    deleteResponse, err := delete.Do(context.Background(), client)
+    if err != nil {
+        fmt.Println("failed to delete document ", err)
+        os.Exit(1)
+    }
+    fmt.Println("deleting document")
+    fmt.Println(deleteResponse)
+
+    // Delete previously created index.
+    deleteIndex := opensearchapi.IndicesDeleteRequest{
+        Index: []string{IndexName},
+    }
+
+    deleteIndexResponse, err := deleteIndex.Do(context.Background(), client)
+    if err != nil {
+        fmt.Println("failed to delete index ", err)
+        os.Exit(1)
+    }
