+
+## Installation
+
+Get the package
+
+   ```bash
+     go get github.com/codescalersinternships/psutil-golang-RawanMostafa
+   ```
+Import the package
+
+  ```go
+     import github.com/codescalersinternships/psutil-golang-RawanMostafa/pkg
+  ```
+
+## Usage
+
+  The psutils package offers different APIs like:
+
+### 1. CPU related APIs
+
+```go
+  cpuInfo, err := psutils.GetCpuInfo()
+    if err != nil {
+        //handle the error
+    }
+```
+
+### 2. Memory related APIs
+
+```go
+   memInfo, err := psutils.GetMemInfo()
+    if err != nil {
+        //handle the error
+    }
+```
+### 3. Processes related APIs
+
+1. ```go
+	procs, err := psutils.GetProcessList()
+    if err != nil {
+        //handle the error
+    }
+   ```
+
+2. ```go
+	procDetails, err := psutils.GetProcessDetails(1)
+    if err != nil {
+        //handle the error
+    }
+   ```
