+{{OLYMPUS_VERSION_NUMBER}}
+
+==========================================
+INSTALLATION INSTRUCTIONS
+
+1) Close any applications which may interfere with installation, including Digital Combat Simulator (DCS) and previous versions of Olympus.
+
+2) If you DO NOT have Olympus already installed, SKIP THIS STEP. If you have already installed Olympus, do the following:
+    	NOTE: If you made any changes to your unit databases or mods.lua file (e.g. to support a third party mod) make a backup of the edited files before proceeding or changes will be lost;
+    	a) If you installed DCS Olympus v1.0.3 using the installer, simply remove it using Windows's "Add or remove programs" application. 
+    	b) If you installed DCS Olympus v1.0.3 using the archived version, remove it by deleting the "...<DCS Saved Games folder>\Mods\Services\Olympus" folder. Do this for every DCS instance you installed Olympus in. 
+       	   Remember to delete any shortcuts you created. Don't worry, they will be created automatically again by the installation script provided in this package.
+
+3) Create a folder named "DCS Olympus" in your "Saved Games" directory and extract all the contents of the downloaded package into it.
+	NOTE:
+    	a) Do not extract the contents of the package directly in your Saved Games folder or in your DCS Saved Games folder. 
+        b) Unlike previous version of Olympus, it is no longer necessary to copy the packaged files into each DCS instance folder.
+
+4) Execute the "installer.bat" script by double-clicking on it. It is located in the folder you created in step 3. Wait for the installation script to complete. Installation may take a couple of minutes, after which the Manager will start automatically.
+	NOTE: depending on your Windows configuration, the script may be called "installer" (without .bat at the end).
+
+5) The Olympus Manager will open. This will allow you to add/remove Olympus to individual DCS instances.
+	Use the Olympus Manager and follow the instructions to install and setup Olympus.
+
+6) Start DCS and run a mission. Make sure it is UNPAUSED.
+
+7) Open Olympus via the shortcut and login using any username and the Game Master password set using the Manager. (NOTE: not your DCS server password).
+	Local installation: run the client from the provided desktop shortcut or start it using the "View and manage instances" page of the Manager. 
+	Dedicated server: users must first start the Olympus server from the provided desktop shortcut or using the "View and manage instances" page of the Manager. 
+			  Then log in using any browser and visiting "http:\\<server IP>:<frontend port>" (frontend port is 3000 by default, but can be edited using the Manager)
+
+8) You can use the manager at any time to change the ports and/or passwords. If you do, REMEMBER TO RESTART OLYMPUS AND DCS.
+
+
+NOTES:
+a) when launching the Manager you will be prompted to allow Electron to create a firewall rule. This is optional and can be denied without effect on the operation of the Manager;
+b) if you are using Olympus on a dedicated server with a router, you must enable port forwarding on the frontend port (3000 by default);
+c) unlike Olympus v1.0.3, running the netsh command is no longer required. It is also no longer required to create firewall rules or port forwarding for the backend port. (Optional) If you already performed this steps in the past you can delete the firewall and netsh rules.
+
+
+==========================================
+UPDATING INSTRUCTIONS
+
+IF YOU ARE UPDATING FROM DCS OLYMPUS v1.0.3, FOLLOW THE "INSTALLATION INSTRUCTIONS".
+
+To update your Olympus installation you have two options:
+a) download the new package from the GitHub releases page, delete the old unpacked package folder, then follow the INSTALLATION INSTRUCTIONS;
+b) run the Olympus Manager. If an update is available you will be given the option to automatically update Olympus from there.
+
+For either options a) or b), remember to close any applications which may interfere with installation, including Digital Combat Simulator (DCS) and previous versions of Olympus.

 # DCS Olympus
-*A real-time web interface to spawn and control units in DCS World*
-
-![alt text](https://github.com/Pax1601/DCSOlympus/blob/main/client/sample.png?raw=true)
 
 ### What is this?
-DCS Olympus is a mod for DCS World. It allows users to spawn, control, task, group, and remove units from a DCS World server using a real-time map interface, similarly to Real Time Strategy games. The user interface also provides useful informations units, like loadouts, fuel, tasking, and so on. In the future, more features for DCS World GCI and JTAC will be available.
+DCS: Olympus is a free and open-source mod for DCS that enables dynamic real-time control through a map interface. The user is able to spawn units/groups, deploy a variety of effects such as smoke, flares, or explosions, and waypoints/tasks can be given to AI units in real-time in a way similar to a classic RTS game. 
 
-### Features and how to use it
-- Spawn air and ground units, with preset loadouts
-    - Double click on the map to spawn a blue and red units, both in the air and in the ground, with preset loadouts for air-to-air or air-to-ground tasks;
-- Control units
-    - Select one ore more units to move them around. Hold down ctrl and click to create a route for the unit to follow;
-- Attack other units
-    - After selecting one ore more units, double click on another unit and select "Attack" to attack it, depending on the available weapons.
+Additionally Olympus is able to run several effects and unit behaviours beyond the core DCS offerings. This includes such things as napalm and white phosphosous explosions, or setting up AA units to fire at players and miss, and more.
+
+It even includes Red and Blue modes which limit your view and powers to just seeing what your coalition sees, with a spawning budget you could play against your friends even with no-one in the game piloting, or have a Red commander working against a squadron of blue pilots, and/or a blue commander working with them. 
+
+Even better it requires no client mods be installed if used on a server
+
+The full feature list is simply too long to enumerate in a short summary but needless to say Olympus offers up a lot of unique gameplay that has previously not existed, and enhances many other elements of DCS in exciting ways 
 
 ### Installing DCS Olympus
-A prebuilt installer will soon be released and available here
+Check the [Wiki](https://github.com/Pax1601/DCSOlympus/wiki) for installation instructions
 
-### Building DCS Olympus
-DCS Olympus is comprised of two modules:
+# Frequently Asked Questions
 
-A "core" c++ .dll module, which is run by DCS and exposes all the necessary data, and provides endpoints for commands from a REST server. A Visual Studio 2017/2019/2022 solution is provided, and requires no additional configuration. The core dll solution has two dependencies, both can be installed using vcpkg (https://vcpkg.io/en/getting-started.html):
-- cpprestsdk: `vcpkg install cpprestsdk:x64-windows`
-- geographiclib: `vcpkg install geographiclib:x64-windows`
-    
-    
-A "client" node.js typescript web app, which can be hosted on the server using express.js. A Visual Studio Code configuration is provided for debugging. The client requires node.js to be installed for building (https://nodejs.org/en/). After installing node.js, move in the client folder and run the following commands:
-- `npm install`
-- `npm -g install`
- 
- After installing all the necessary dependencies you can start a development server executing the *client/debug.bat* batch file, and visiting http:\\localhost:3000 with any modern browser (tested with updated Chrome, Firefox and Edge). However, it is highly suggested to simply run the `Launch Chrome against localhost` debug configuration in Visual Studio Code.

+### I need troubleshooting guidance, please help? ###
+Read through the [Installation Guide](https://github.com/Pax1601/DCSOlympus/wiki) to ensure you have setup Olympus correctly.
+
+Read through [Setup Troubleshooting](https://github.com/Pax1601/DCSOlympus/wiki/Setup-Troubleshooting) for common issues and solutions.
+
+Read through the [Olympus User Guide](https://github.com/Pax1601/DCSOlympus/wiki/2.-User-Guide) to learn how to use Olympus.
+
+If you're still having issues after trying the steps above, please post in the ⁠community-support channel with the following:
+
+A detailed description of your issue
+Your Olympus log file \user home folder\AppData\Local\Temp\Olympus_log.txt for some it might be in \DCS Saved Games folder\Logs\Olympus_log.txt
+Your DCS log file \DCS Saved Games folder\Logs\dcs.log
+
+Screenshots of any relevant screens or issues and any other pertinent information.
+
+### Can I join up and help out with the project? ###
+Absolutely, join the discord and ping any of the developers to get briefed.
+
+### Can I be a beta/alpha-tester? ###
+Same as above!
+
+### Do you have a roadmap? ###
+We do not have a roadmap no, we have a laundry list of things we are hoping to do. 
+
+These include but are not limited to:
+1) Enhancements to helicopter play
+2) More features around use of ground units
+3) More unique effects and behaviours
+4) ATC/AIC features
+5) Usability features like unit painters etc
+
+However we cannot commit to specific features, feature release order, or timelines, please remember this isn't our job and we work on it in our free time because we love DCS
+
+### Does Olympus support mods? ###
+Generally OIympus will not have any issues with other mods, however you may need to tell olympus about modded units in order to be able to dynamically spawn them etc
+Keep in mind that any mods you do choose to spawn your players will need to have, some mod unit just appear as a su27 or leo2 etc. When a player is missing them, others can cause client crashes. So be smart about how you use them.
+
+### Is Olympus compatible with mission scripts? ###
+We have tried hard to keep Olympus from interfering with other scripts, we have tested with a variety of new and old mission scripts and generally expect it will not be an issue.
+
+However we cannot foresee everything people come up with so we suggest testing with what you have in mind once olympus releases
+
+### How does it work? ###
+The quick answer is magic. 
+The long answer is well all the code is there for you to read. 
+The middle answer is a bit like SRS does. Olympus consists of two parts. 
+
+(A) Olympus back end: A dll, run by DCS, that sends data out and gets commands in via a REST API;
+(B) Webserver exe: The one you start when starting the server via the desktop shortcut. 
+
+A and B never communicate when you connect the client you download the web page and some other minor stuff from B, and you get the DCS data from and send commands to A.
+
+### How much does Olympus impact performance? ###
+Olympus by itself should not have a noticeable impact on server performance, however the ability for the user to spawn arbitrary units and command engagements means Olympus can be used in such a way that brings the game to it's knees.
+
+Be cognizant of how you play, whether it's done through Olympus or the mission editor 500 MLRS units firing at once is not going to go over well with most servers
