-# How to execute source code (執行方法)
+# How to execute source code (透過原始碼的執行方法)
 1: download chromedrive to "webdriver" folder:
 http://chromedriver.chromium.org/downloads
 
-2: <code>pip install selenium</code>
+change the chromedrive in chrome_tixcraft.py, source code:
+<code>chromedriver_path =Root_Dir+ "webdriver/chromedriver"</code>
+the default path is the script path + "webdriver/chromedriver", my suggestion is make a new directory then move the chromedrive under new folder.
 
-3: <code>python settings.py</code>
+2: <code>pip install selenium</code> or <code>pip3 install selenium</code>
+
+3: <code>python settings.py</code> or <code>python3 settings.py</code>
+
+PS: this script able to run in python2 or python3.
+PS: 原始碼可以在python2 或 python3 下執行，請先確定你的python 執行環境下已安裝 selenium 或相關的套件，參考 pip-reg.txt。還需要手動下載新版的 chromedrive 或 firefox drive(geckodriver), 建議在 source code 下建立一個 webdrive 的目錄，並把 chromedirve 的執行檔放進去，或是手動地修改 chrome_tixcraft.py 裡的 chromedriver_path 為你環境下能存取到 chromedrive 的路徑。最後透過 python 或 python3 執行 settings.py 就可以有 GUI 的設定界面。
