 I have built a tiny client that receives key-value entries from user and stores it on IPFS DAG, returning an explorable URL to play with.
 
-## Instructions
+## Usage
 
-1. Clone the repo with the following command:
-```sh
-git clone [email protected]:0zAND1z/ipldcrud.git
-```
+Here is a sample main.go file for your quick reference:
+
+```go
+package main
+
+import (
+	"bufio"
+	"encoding/json"
+	"fmt"
+	"os"
+
+	ipldcrud "github.com/0zAND1z/ipldcrud"
+)
+
+func main() {
+	sh := ipldcrud.InitShell("https://ipfs.infura.io:5001")
+
+	keyValueMap := make(map[string]interface{})
+
+	scanner := bufio.NewScanner(os.Stdin)
+
+	fmt.Println("Enter value for the key field: ")
+	scanner.Scan()
+	inputKey := scanner.Text()
+
+	fmt.Println("Enter value for value field: ")
+	scanner.Scan()
+	inputValue := scanner.Text()
+
+	keyValueMap[inputKey] = inputValue
+
+	// Converting into JSON object
+	entryJSON, err := json.Marshal(keyValueMap)
+	if err != nil {
+		fmt.Println(err)
+	}
+
+	// Display the marshaled JSON object before sending it to IPFS
+	jsonStr := string(entryJSON)
+	fmt.Println("The JSON object of your key-value entry is:")
+	fmt.Println(jsonStr)
+	cid := ipldcrud.Set(sh, entryJSON)
+	fmt.Println("CID: ", cid)
+
+	// Fetch the details by reading the DAG for key "inputKey"
+	fmt.Printf("READ: Value for key \"%s\" is: ", inputKey)
+	res, err := ipldcrud.Get(sh, cid, inputKey)
+	if err != nil {
+		fmt.Println(err)
+	}
+	fmt.Println(res)
+}
 
-2. Run the program to initaite dialog:
-```sh
-go run main.go
 ```
 
-3. Once you run the main.go, a nice ASCII version of the IPFS logo pops up, asking you to enter a key and a value.
+1. Once you run the main.go, a simple console pops up, asking you to enter a key and a value.
 
-4. After entering two string values, it will create a dag entry based on the input data and return back the hash along with the query results.
+2. After entering two string values, it will create a dag entry based on the input data. It will subsequently query the same data and return back the result along with the query results.
