 ## Installation <a name="installation"></a>
 
 ### Go <a name="Go"></a>
+The detailed download and installation guide can be found at official website of [**Go**](https://go.dev/doc/install).
 
+For Linux:
 ```
+# 1. Download Go Binary Archive
+wget https://golang.org/dl/go1.18.4.linux-amd64.tar.gz
 
-```
+# 2. Extract it
+tar -xzf go1.18.4.linux-amd64.tar.gz -C /usr/local/
 
-### GoMobile <a name="GoMobile"></a>
+# 3. Add PATH Variables
+sudo nano /etc/profile
+export PATH=$PATH:/usr/local/go/bin
+source /etc/profile
 
+# 4. Check Go Version
+go version
 ```
+You can refer to the official documentation for setting **GOPATH**.
 
+### GoMobile & Gobind <a name="GoMobile & Gobind"></a>
+After installing Go, we need gobind. **Gobind** is a tool that generates language bindings that make it possible to call Go functions from Java and Objective-C. It is called internally by **gomobile** which can help us build cross-platform applications.
 ```
+go install golang.org/x/mobile/cmd/gomobile@latest
 
-## VPN-Hole <a name="VPN-Hole"></a>
+# To compile Android APK and IOS Apps
+gomobile bind [-target android|ios|iossimulator|macos|maccatalyst] [-bootclasspath <path>] [-classpath <path>] [-o output] [build flags] [package]
+```
 
+## VPN-Hole <a name="VPN-Hole"></a>
+To clone and build VPN-Hole Library:
 ```
+git clone https://0xacab.org/leap/vpn-hole.git
 
+cd vpn-hole
 ```
 
 ### Instructions <a name="Instructions"></a>
-
+To load all of the packages in the main module:
+```
+# If go.mod and go.sum are present then,
+# Run 
+go mod tidy
+```
+If go.mod and go.sum are missing from the cloned repository, then:
+```
+go mod init [module-path]
+``` 
 
 ## Build & Run <a name="Build & Run"></a>
 
 ```
 # build the library
-
+go build
+```
+An executable binary file would be generated for the library.
+```
 # executing the binary
 
 ```
 
-## Integration <a name="Integration"></a>
 
+## Integration <a name="Integration"></a>
+To integrate the VPN-Hole Library with existing cross-platform applications, we will be using gomobile to compile and bind it.
