+Let us create a simple echo bot
+
+- follow  [these](https://github.com/rubenlagus/TelegramBots/blob/master/eclipse%20configuration.md) steps to work with eclipse
+
+- got to org.telegram and edit `BuildVars.java` and fill it out
+
+
+```
+public static final Boolean debug = true;
+public static final String pathToLogs = "./";
+public static final String linkDB = "jdbc:mysql://[IP_OF_YOU_MYSQL_SERVER]:3306/[DATABASE]?useUnicode=true&characterEncoding=UTF-8";
+public static final String controllerDB = "com.mysql.jdbc.Driver";
+public static final String userDB = "[YOUR_DB_USERNAME]";
+public static final String password = "[YOUR_SECRET_DB_PASSWORD]";
+```
+
+For our project those settings are enough. 
+
+[DATABASE]: your database. i.e. myProject
+
+
+- next, go to org.telegram and edit `BotConfig.java`
+Here we must fill in our login credentials for our bot.
+
+```
+public static final String TOKENMYPROJECT = "[YOUR_TOP_SECRET_TOKEN]";
+public static final String USERNAMEMYPROJECT = "myProjectBot";
+```
+[YOUR_TOP_SECRET_TOKEN]: your token you got from the [BotFather](https://telegram.me/BotFather)
+
+
+- go to org.telegram.updatehandlers and create a new class. This class is responsible for your bot actions. (in our case just return the text back). This class should extending `TelegramLongPollingBot`.
+
+
+It should look similiar like this:
+
+
+
+
+```
+package org.telegram.updateshandlers;
+
+import org.telegram.telegrambots.api.objects.Update;
+import org.telegram.telegrambots.bots.TelegramLongPollingBot;
+
+public class MyProjectHandler extends TelegramLongPollingBot {
+
+        @Override
+        public String getBotUsername() {
+                // TODO Auto-generated method stub
+                return null;
+        }
+
+        @Override
+        public void onUpdateReceived(Update arg0) {
+                // TODO Auto-generated method stub
+                
+        }
+
+        @Override
+        public String getBotToken() {
+                // TODO Auto-generated method stub
+                return null;
+        }
+
+        
+        
+}
+```
+
+Then you can program your bot. First edit getBotToken() and getBotUsername(). Simply return your credentials mentioned in BotConfig. So for example `return BotConfig.USERNAMEMYPROJECT;`
+
+
+
+The onUpdateReceived() method could look like this:
+
+```     
+        @Override
+        public void onUpdateReceived(Update update) {
+                
+                //check if the update has a message
+                if(update.hasMessage()){
+                        Message message = update.getMessage();
+                        
+                        //check if the message has text. it could also  contain for example a location ( message.hasLocation() )
+                        if(message.hasText()){
+                                
+                                //create a object that contains the information to send back the message
+                                SendMessage sendMessageRequest = new SendMessage();
+                                sendMessageRequest.setChatId(message.getChatId().toString()); //who should get the message? the sender from which we got the message...
+                                sendMessageRequest.setText("you said: " + message.getText());
+                                try {
+                                        sendMessage(sendMessageRequest); //at the end, so some magic and send the message ;)
+                                } catch (TelegramApiException e) {
+                                        //do some error handling
+                                }//end catch()
+                        }//end if()
+                }//end  if()
+                
+        }//end onUpdateReceived()
+```
+- go to the `Main.java` in org.telegram and register your updatehandler
+```
+public static void main(String[] args) {
+
+        TelegramBotsApi telegramBotsApi = new TelegramBotsApi();
+        try {
+            telegramBotsApi.registerBot(new MyProjectHandler());
+        } catch (TelegramApiException e) {
+            BotLogger.error(LOGTAG, e);
+        }//end catch()
+    }//end main()
+```
