-# Datetime-client-RawanMostafa
+# Datetime Client 
+
+This repository implements an http datetime client that accepts the response of a datetime server
+
+## Table of Contents
+
+- [Installation](#installation)
+- [Usage](#usage)
+
+
+## Installation
+
+1. Clone the repository
+
+   ```bash
+   git clone https://github.com/codescalersinternships/Datetime-client-RawanMostafa.git
+   ```
+
+2. Install the dependencies
+    ```bash
+    go mod download
+    ```
+
+## Usage
+
+  You can configure our client using different ways:
+
+### 1. Using flags
+
+   ```bash
+    go run cmd/main.go [flags]
+   ```
+#### Flags:
+   - baseUrl=BASEURL 
+   - port=PORT
+   - endpoint=ENDPOINT
+
+### 2. Using environment variables
+This is used in case of no passed flags
+
+   ```bash
+    export VARNAME="my value"
+    go run cmd/main.go 
+   ```
+#### Environment variables:
+   - DATETIME_BASEURL 
+   - DATETIME_PORT
+   - DATETIME_ENDPOINT
+
+### 2. Using the default configurations
+Our application provides default configurations in case no flags are provided and environment variables aren't set
+
+   ```bash
+    go run cmd/main.go 
+   ```
+#### Default configs:
+  ```go
+    const defaltBaseUrl = "http://localhost"
+    const defaultEndpoint = "/datetime"
+    const defaultPort = "8083"
+  ```
+
+#### Extra Utilities
+  - Check this function to get environment variables : [`decideConfigs`](https://github.com/codescalersinternships/Datetime-client-RawanMostafa/blob/9c3cc7ecf671057648e10d07c550c171b51747a6/cmd/main.go#L43-L76)
