 While this model has good stability, it can still be influenced by the choice of models used in combination.
 
 ## How to Use
-1、For QR codes, it is recommended to use version 5 or 6.
+1、For QR codes, it is recommended to use version 5 or 6,and process the area outside the QR code into gray,This will extend the image more efficiently..
 2、You can set the parameters according to the original A1111 settings: Step 20 / CFG 7 / Use Euler A for sampling and DPM++ 2M SDE Karras for relative stability.
 3、A smaller size might lead to a reduction in scanning rate or image quality. It is recommended to use a minimum size of 768x768.
 4、Please try with low weights first, then gradually increase the control net weights using the same seed to achieve an excellent final product.

 雖然這個模型的穩定性遠優於從前，但是依然會受到選擇使用搭配的模型影響
 
 ## 如何使用
-1、QRcode版本建議使用5或6
+1、QRcode版本建議使用5或6，並將QR code以外的區域改成灰色，這將能更有效的將畫面延伸。
 2、參數可依照A1111原始參數設定就好(步數 20 / CFG 7 / 取樣方式使用Euler a 和DPM++ 2M SDE Karras相對穩定)
 3、較小的尺寸可能會導致掃描率或是畫面品質降低，建議最少使用768*768尺寸
 4、請以低權重嘗試後再使用相同種子將控制網權重慢慢往上調整，以獲得優秀的成品
