+# Telegram Bot Java Library
+A simple to use library to create Telegram Bots in Java (Still Beta Version)
+
+## Translations
+Bots are now supporting multilanguage. If you want to add your own, feel free to translate at [transifex](https://www.transifex.com/projects/p/telegrambots/)
+
+## Contributions
+Feel free to fork this project, work on it and then make a pull request. Most of the times I will accept them if they add something valuable to the code. 
+
+Please, **DO NOT PUSH ANY TOKEN OR API KEY**, I will never accept a pull request with that content.
+
+## Webhooks vs GetUpdates
+Both ways are supported (but I still didn't tested webhooks). To change between them, just go to *BuildVars.java* and change variable *useWebHook* value.
+
+I recommend using getUpdates methods. Webhooks only works using a certificated that is not self-signed
+
+## Example bots
+Open them and send them */help* command to get some information about their capabilities:

+# How to use TelegramBots with Eclipse
+
+
+### Step 1: Install Maven
+To get started, you need to install the Maven-Plugin for Eclipse. Click on Help > Eclipse Marketplace. After it finished loading, search for “Maven”. 
+Now install **“Maven (Java EE) Integration for Eclipse WTP”**. You have to restart, after the installation is completed.
+
+### Step 2: Download the Project
+Now you need to get the project itself. 
+Visit [TelegramBots - github.com][1] and choose “Download Zip”, to download the zip-file. [Here] is a direct link if you are lazy.
+
+### Step 3: Create folder
+Now let’s setup the project-folder. Go to your Eclipse-Workspace and create a folder (name it whatever you want it to be called). I just named it **“TelegramBotApi”**. Afterwards copy everything from the zip-file into that folder.
+
+### Step 4: Import project
+To import your project into the workspace you have to go to File > Import > (Folder) Maven > Existing Maven Projects > Next. Choose the folder, you have created in Step 3. In my case: **“TelegramBotApi”**. Click on finish and let Maven import the dependencies.
+
+### Step 5: Setting the compliance level
+In this last step you need to change the Compiler compliance level. To do this right-click on your Project (in my case **“TelegramBotApi”**) > Properties > Java Compiler. Uncheck the “Use compliance from…” if necessary and set it to 1.7
+
+*Now you are done. Everything should work fine. You need to set your Bot-Token in the BotConfig.java, afterwards you can run Main.java to check.*
