i need to make a second branch my main branch code example

Example 1: merge git branch

1. //pull the latest changes of current development branch if any        
git pull (current development branch)

2. //switch to master branch
git checkout master 

3. //pull all the changes if any
git pull

4. //Now merge development into master    
git merge development

5. //push the master branch
git push origin master

Example 2: git merge branch to master

$ git checkout master
Switched to branch 'master'
$ git merge iss53
Merge made by the 'recursive' strategy.
