How to push changes to branch?

Question

Can you explain me how to use git in case, when I have access to repository:

• How to download repository
• How to push changes in selected branch
• How to select branch to push

I tried these steps

git init
git clone git.repository
git pull develop  (where develop is branch)
git add .
git commit -m "m"
git push origin develop

Result is:

* branch            develop    -> FETCH_HEAD
fatal: refusing to merge unrelated histories

What I do wrong?

3 Steps to Commit your changes

Suppose you have created a new branch on GitHub with the name feature-branch.

FETCH

    git pull --all         Pull all remote branches
    git branch -a          List all branches now

Checkout and switch to the feature-branch directory. You can simply copy the branch name from the output of branch -a command above

git checkout -b feature-branch

VALIDATE

Next use the git branch command to see the current branch. It will show feature-branch with * In front of it

git branch   check current branch
git status   check the state of your codebase       

COMMIT

git add .   add all untracked files
git commit -m "Rafactore code or use your message"

Take update and the push changes on the origin server

 git pull origin feature-branch
 git push origin feature-branch

OR you can rebase with the master before commit

git fetch
git rebase origin/master
git push origin feature-branch
