+# Geoip Module
 
-This module is used to get information about the geographical location of an IPv4 or IPv6 address. 
+The `geoip` module provides a simple way to determine the geographical location of an IPv4 or IPv6 address.
+This includes details such as longitude, latitude, country, city, and continent.
 
+## Features
 
-## Usage
-
-To get the location of the system calling this function, use exported method `Fetch` from the package `geoip`
+- **Failover Mechanism:** The module attempts to fetch location data from multiple services to ensure high availability. If one URL fails, it logs the error and retries with the next URL.
+- **Structured Location Data:** Returns structured data in a `Location` struct for easy integration.
 
-1. use `geoip.Fetch()`:
+```go
+type Location struct {
+	Longitude   float64 `json:"longitude"`
+	Latitude    float64 `json:"latitude"`
+	Continent   string  `json:"continent"`
+	Country     string  `json:"country_name"`
+	CountryCode string  `json:"country_code"`
+	City        string  `json:"city_name"`
+}
+```
 
-    This method uses 3 paths of geoip, It starts with first path of `geoipURLs` if any error was produced it continues and tries out the next path, REturnes the default unknown location and the error in case it couldn't receive correct response from all paths.
-
-## Tests
+## Usage
 
-`geoip_test.go` tests the driver function `getLocation` which is called by the exported function `Fetch`
-It mainly tests and validates:
-1. Correct response.
-2. Wrong response code.
-3. Wrong response body.
+The module provides a single exported function: `Fetch`. 
 
-#### Remark : Tests are computed on all 3 paths of `geoipURLs` to ensure correctness.
+The `Fetch` function retrieves the geographical location of the system calling the function.
