+# Keploy Go-SDK
+
+This is the client SDK for Keploy API testing platform. There are 2 modes:
+1. **Capture mode**
+    1. Captures requests, response and all external calls and sends to Keploy server.
+    2. After keploy server removes duplicates, it then runs the request on the API again to identify noisy fields.
+    3. Sends the noisy fields to the keploy server to be saved along with the testcase. 
+2. **Test mode**
+    1. Fetches testcases for the app from keploy server. 
+    2. Calls the API with same request payload in testcase.
+    3. Mocks external calls based on data stored in the testcase. 
+    4. Validates the respones and uploads results to the keploy server

+## Installation
+```bash
+go get -u github.com/keploy/go-sdk
+```
+## Usage
+
+```go
+import(
+        "github.com/keploy/go-sdk/integrations"
+	"github.com/keploy/go-sdk/keploy"
+)
+```
+
+Create your app instance
+```go
+kApp := keploy.NewApp("<app_name>", "<license_key>", "<keploy_host>", "app_ip_addr", "app_port")
+```
+For example: 
+```go
+kApp := keploy.NewApp("my_app", "adkjhf9adf9adf", "", "0.0.0.0", "8080")
+```
+    
+## Configure
+```
+export KEPLOY_SDK_MODE="test"
+```
+### KEPLOY_SDK_MODE
+There are 3 modes:
+ - **Capture**: Sets to capture mode.
+ - **Test**: Sets to test mode. 
+ - **Off**: Turns off all the functionality provided by the API
+
+**Note:** `KEPLOY_SDK_MODE` value is case sensitive.
