+[h1]Usage (single player)[/h1]
+1. Subscribe to this mutator;
+2. Start KF2; 
+3. Open console (`) and input:
+[b]open KF-BioticsLab?Mutator=CTI.CTIMut[/b]
+(replace the map and add the parameters you need)
+4. <Enter>.

+
+1. Open your [b]PCServer-KFEngine.ini[/b] / [b]LinuxServer-KFEngine.ini[/b];
+2. Add the following string to the [b][OnlineSubsystemSteamworks.KFWorkshopSteamworks][/b] section (create one if it doesn't exist):
+[b]ServerSubscribedWorkshopItems=2830826239[/b]
+3. Start the server and wait while the mutator is downloading;
+4. Add mutator to server start parameters: [b]?Mutator=CTI.CTIMut[/b] and restart the server.
+
+[h1]Setup (KFCTI.ini)[/h1]
+Config will be created at the first start.
+
+Set [b]UnlockDLC=True[/b] to allow all players to buy DLC weapons.
+
+Set [b]bForcePreloadContent=True[/b] to preload weapon models and have no lags during trader time.
+
+Use [b][CTI.RemoveItems][/b] to remove items from the trader inventory.
+For example: [b]Item=KFGame.KFWeapDef_Mac10[/b] will remove MAC10 from sale.
+Set [b]bAll=True[/b] if you want to remove all items (can be useful if you want to set the entire sale list in the [b][CTI.AddItems][/b] section yourself).
+
+Use [b][CTI.AddItems][/b] to add items to the trader inventory.
+For example: [b]Item=WeaponPack.KFWeapDef_XM25[/b] will add [url=https://steamcommunity.com/sharedfiles/filedetails/?id=1147408497]XM25[/url] to sale.

+[h1]Notes[/h1]
+📌 Mutator does not contain custom weapons. You must have the required weapon packs in your subscriptions to be able to add them to the trader.
+📌 If you are using this mutator to add weapons, you should [b]not[/b] use mutators from weapon packs (just having them in subscriptions is enough).
+📌 Unlike [url=https://steamcommunity.com/sharedfiles/filedetails/?id=2193261170]DLC Weapon Unlocker[/url], a different method is used here.
+[url=https://steamcommunity.com/sharedfiles/filedetails/?id=2193261170]DLC Weapon Unlocker[/url] creates clones of DLC weapons and adds them to the trader. This allows you not to replace any classes in the game, so Hunter mutator has better compatibility with other mutators. However, those who have already purchased the DLC will not be able to use their skins on clones.
+CTI unlocks DLC weapons differently - it changes the trader filter allowing you to buy original DLC weapons without restrictions. Those who bought the DLC can use their skins and you don't need to update the mutator when new kf2 updates are released - unlocking will work with future weapons as well. However, when you set UnlockDLC=True CTI replaces the [b]KFGFxMoviePlayer_Manager[/b] class, so CTI may not be compatible with mods that replaces this class too. If you notice any compatibility issues, try turning off UnlockDLC.
+You can use this method or use a [url=https://steamcommunity.com/sharedfiles/filedetails/?id=2193261170]DLC Weapon Unlocker[/url] - choose what suits you best.

+Add/Remove Items in the Trader's Inventory  
+
+# Features
+- remove and/or add items;
+- unlock DLC weapons;
+- correct items sorting (by price);
+- can preload weapon models (no lags during trader time);

+
+# Usage & Setup
+[See steam workshop page](https://steamcommunity.com/sharedfiles/filedetails/?id=2830826239)
+
+# Build
+**Note:** If you want to build/test/brew/publish a mutator without git-bash and/or scripts, follow [these instructions](https://tripwireinteractive.atlassian.net/wiki/spaces/KF2SW/pages/26247172/KF2+Code+Modding+How-to) instead of what is described here.
+1. Install [Killing Floor 2](https://store.steampowered.com/app/232090/Killing_Floor_2/), Killing Floor 2 - SDK and [git for windows](https://git-scm.com/download/win);
+2. open git-bash and go to any folder where you want to store sources:  
+`cd <ANY_FOLDER_YOU_WANT>`  
+3. Clone this repository and go to the source folder:  
+`git clone https://github.com/GenZmeY/KF2-CustomTraderInventory && cd KF2-CustomTraderInventory`
+4. Download dependencies:  
+`git submodule init && git submodule update`  
+5. Compile:  
+`./tools/builder -c`  
+5. The compiled files will be here:  
+`C:\Users\<USERNAME>\Documents\My Games\KillingFloor2\KFGame\Unpublished\BrewedPC\Script\`
+
+# Testing
+Open git-bash in the source folder and run command:  
+`./tools/builder -t`  
+(or `./tools/builder -ct` if you haven't compiled the mutator yet)  
+
+A local single-user test will be launched with parameters from `builder.cfg` (edit this file if you want to test mutator with different parameters).
+
+# Bug reports
+If you find a bug, go to the [issue page](https://github.com/GenZmeY/KF2-CustomTraderInventory/issues) and check if there is a description of your bug. If not, create a new issue.  
+Describe what the bug looks like and how reproduce it.
