Viewing the chalenge page telling us that it's issue with commit un github 
```Hello World!!
I told the developer to be careful while making a git commit..
Developed by [Altaf Shaikh](https://altafshaikh.ml/)```
after visiting the Developer page i got into his github abbount and i noticed the first repo [past_never_leaves](https://github.com/altafshaikh/past_never_leaves) because it's descreption said :  ` Restcon 2020 CTF Challenge `
after cloning the repo with `git clone https://github.com/altafshaikh/past_never_leaves.git`
i started with viewing the logs `git log`
and i noticed that there is deleted file 
so i started with finding the difference between each commit and the first one 
`git log | grep 'commit'`to list all the commits and after comparing every commit with the first one i got this `git diff af671d22a 9c723aed`
which gaved me the flag 
# Flag `RESTCON{g1t_ch3ck0ut}`
