+# IsolatedOS
+Alien Isolation inspired fan made 32 bit real operating system.
+# Installation
+Download ISO file in releases page and use an emulator to run it. 
+Operating system can be run in legacy bios mode on any computer in theory but **I strongly suggest you to run it on virtual device**.
+# How to build
+## Required Packages
+Install the required packages to compile operating system.
+```
+gcc
+nasm
+qemu-kvm
+```
+Note: qemu-kvm package is required for testing iso
+## Build Scripts
+Open a terminal in project root directory and run script files.
+```
+chmod +x build.sh
+chmod +x run.sh
+./build.sh
+./run.sh
+```
+To build and run
+```
+./build.sh && ./run.sh
+```
+# How to change messages in OS
+To change messages in OS open vgasrc.cpp file in winsis directory and change following lines.
+```
+// PERSONAL:
+#define _PersonalCount 2
+const char* personal_title = "CONFIGURING MESSAGES";
+const char* personal[_PersonalCount] = {
+    "ALL MESSAGES CAN BE EDITTED ON TOP OF THE VGASRC CPP SOURCE",
+    "FILE"
+};
+
+// UTILITIES
+#define _UtilitiesCount 1
+const char* utilities_title = "COMPILATION OF SOURCE";
+const char* utilities[_UtilitiesCount] = {
+    "LOOK AT BUILD SHELL FILE"
+};
+
+// ABOUT
+#define _AboutCount 5
+const char* about_title = "ABOUT ISOLATED OS";
+const char* about[_AboutCount] = {
+    "ISOLATED OS VERSION A",
+    "THIS OPERATING SYSTEM IS DEVELOPED FOR ENTERTAINMENT PURPOSES",
+    "INSPIRED BY FAMOUS VIDEO GAME AND NOT RELATED WITH ANY TRADEMARK",
+    "OF IT",
+    "PROJECT LICENSED UNDER GPL VERSION TWO"
+};
+```
+If you change the line count you should change '_PersonalCount, _UtilitiesCount or _AboutCount' as well.
+# Login Password
+Default login password is 'ADMIN'.<br>
+You can change password in vgasrc.cpp file.
+```
+const char* passwd = "ADMIN";
+
+```
