+# Multitrainer [![Build Status](https://travis-ci.org/Rochet2/TrinityCore.svg?branch=multitrainer_3.3.5)](https://travis-ci.org/Rochet2/TrinityCore)
+
+#### About
+This patch was coded originally by [CyberMist2](https://github.com/CyberMist2).  
+Multitrainer allows you to show multiple different trainer windows on an NPC.
+
+Source: http://rochet2.github.io/Multitrainer.html
+
+#### Installation
+
+Available as:
+- Direct merge: https://github.com/Rochet2/TrinityCore/tree/multitrainer_3.3.5
+- Diff: https://github.com/Rochet2/TrinityCore/compare/TrinityCore:3.3.5...multitrainer_3.3.5.diff
+- Diff in github view: https://github.com/Rochet2/TrinityCore/compare/TrinityCore:3.3.5...multitrainer_3.3.5
+
+Using direct merge:
+- open git bash to source location
+- do `git remote add rochet2 https://github.com/Rochet2/TrinityCore.git`
+- do `git pull rochet2 multitrainer_3.3.5`
+- use cmake and compile
+
+Using diff:
+- DO NOT COPY THE DIFF DIRECTLY! It causes apply to fail.
+- download the diff by __right clicking__ the link and select __Save link as__
+- place the downloaded `multitrainer_3.3.5.diff` to the source root folder
+- open git bash to source location
+- do `git apply multitrainer_3.3.5.diff`
+- use cmake and compile
+
+#### Usage
+The NPC is required to have `npcflag` set to `17`. The `trainer_type` can be `0`.  
+In C++ you can pass the trainer entry to `SendTrainerList` function.  
+In SQL in `world` database you can set the trainer entry to the `gossip_menu_option` table `ActionMenuID` column for an option that has `OptionType` set to `5`.
