@ -199,8 +200,24 @@ You don't need to spend a lot of money into hosting your own telegram bot. Basic
1. Hosting on your own hardware. It can be a Mini-PC like a Raspberry Pi. The costs for the hardware (~35€) and annual costs for power (~7-8€) are low. Keep in mind that your internet connection might be limited and a Mini-Pc is not ideal for a large users base.
2. Run your bot in a Virtual Server/dedicated root server. There are many hosters out there that are providing cheap servers that fit your needs. The cheapest one should be openVZ-Containers or a KVM vServer. Example providers are [Hetzner](https://www.hetzner.de/ot/), [DigitalOcean](https://www.digitalocean.com/), (are providing systems that have a high availability but cost's a bit more) and [OVH](https://ovh.com)
For a deeper explanation for deploying your bot on DigitalOcean please see the [Lesson 5. Deploy your bot](https://monsterdeveloper.gitbooks.io/writing-telegram-bots-on-java/content/lesson-5.-deploy-your-bot.html) chapter in [MonsterDeveloper](https://github.com/MonsterDeveloper)'s book
## <a id="how_to_compile"></a>How can I compile my project? ##
This is just one way, how you can compile it (here with maven). The example below below is compiling the TelegramBotsExample repo.

## <a id="sendmessage_deprecated"></a>Method ```sendMessage()``` (or other) is deprecated, what should I do? ##
Please use ```execute()``` instead.
Example:
```java
SendMessage sn = new SendMessage();
//add chat id and text
execute(sn);
```
If you extend ```TelegramLongPollingCommandBot```, then use ```AbsSender.execute()``` instead. Example:
## <a id="example_webhook"></a>Is there any example for WebHook? ##
Please see the example Bot for https://telegram.me/SnowcrashBot in the [TelegramBotsExample]() repo and also an [example bot for Sping Boot](https://github.com/UnAfraid/SpringTelegramBot) from [UnAfraid](https://github.com/UnAfraid) [here](https://github.com/UnAfraid/SpringTelegramBot/blob/master/src/main/java/com/github/unafraid/spring/bot/TelegramWebhookBot.java)
