Git - merging commits in pull request, when everything before was done through github.com
<p>as title says, I want to merge commits in pull request, but everything before, like commits, making pull request, commiting to branch, that is in pull request, was done at website github.com.
I thought that its easier do this at website, just few clicks and no problem, but with these more complicated things its better do it through terminal.</p>

<p>What I have only done</p>

<p><code>git clone https://github.com/...
cd repository_name</code></p>

<p>So question is - what should I do now, to merge my commits in pull request? I dont have here branches, that I see at github.com, so I even dont know how to switch to branch, that is connected with that pull request.</p>
