Install software on csdn

Csdn is indeed a good place.

I logged on to csdn today and found that there was such a place (I am ashamed that my account does not know how many years I have applied, I decided to settle down here. From then on, I want to stick to the fine tradition of living and learning in my country, study hard, and develop every day, record your learning details here (save your time and forget it when you use it, so you can still look for it here ). Well, I am very touched and excited.

I want to know what to do later, and listen to the next decomposition, I will download the materials.
