very simple actually can be ran in glitch. (if you want to do some just import this into glitch)
Step 1: Put your codes and HTTP/Socks5 proxies in the folder (You can remove codes.txt and proxies.txt) Step 2: Open index.js in a text editor. (You can skip step 2, step 3 and step 4 if you want to generate it automatically) Step 3: Change codes.txt and proxies.txt to what your file names are for those. (You can also set options!) Step 4: Save the file Step 5: Open Command Prompt (Windows: windows key + r, then type 'cmd' without quotes. Mac: command + space then type 'Terminal' without quotes.) Step 6: Navigate to the folder in Command Prompt (Search it up on the internet, I cant explain) Step 6: Type 'npm install' Step 7: Type 'node index.js' Step 8: It will now generate and check the codes!
