   Chat with BotFather https://telegram.me/botfather, send /newbot command to create a new bot, and get the token, for example 110201543:AAHdqTcvCH1vGWJxfSeofSAs0K5PALDsaw
2. Chat with your bot, use your Telegram account.
3. Get your telegram account's ID. Send any message to https://t.me/RawDataBot, This bot will return the raw message from Telegram(json format). ["message"]["from"]["id"] is your account's ID. eg 12345678.
4. Afterward, now you can send a message via tgsend.
   tgsend -token 110201543:AAHdqTcvCH1vGWJxfSeofSAs0K5PALDsaw -chatid 12345678 -message "Hello World."
