Now a PR can be created on GitHub
Check the Pull requests tab on GitHub and its subsections like Commits and Files changed to review (and, hopefully, approve) PRs.

Deleting branch after a PR

The branch can be safely deleted after merging

The deleted branch can be restored from GitHub UI - check the Restore branch button at the bottom of the closed PR.

git stash # use it if you forgot to commit some changes before merging
git checkout master # have to switch branch before deleting it
git branch -d first-pr 
git push origin --delete first-pr # deleting and pushing
> To https://github.com/TsarSPb/hello-world.git
>  - [deleted]         first-pr
git pull origin # pulling current state
> remote: Counting objects: 100% (1/1), done.
> Unpacking objects: 100% (1/1), 636 bytes | 5.00 KiB/s, done.
>  * branch            master     -> FETCH_HEAD

>  1 file changed, 29 insertions(+), 1 deletion(-)
git checkout -d second-pr # creating a new branch for the second PR
git stash apply # use it if you have some code hidden in the stash
> On branch second-pr
> Changes not staged for commit:
>   (use "git add <file>..." to update what will be committed)
>   (use "git restore <file>..." to discard changes in working directory)
>         modified:   README.md
> 
> no changes added to commit (use "git add" and/or "git commit -a")
git commit -a -m "Added info about stashing and deleting old branches. All set for the second PR"
git push origin second-pr
