ABOUT GIT ->
1. git is tool for version control
2. github is website use for collaborative code and version control also . here the all code is saved in repo

1. step install git from atlassians git insatlation guide
2. create an account in github create repostiory
3. now open vs code and clone the repo using gitbash
  aand command is	
	git clone "linkofrepo"

4. now do the changes then use below command to add all changes to tracker of git
	git add . 
5. now use commit to save
	git commit -m "title" -m "description"

6. if all is good then push to github 
	git push origin master 

thats alll..........................................

_________________branches

now you have working project and you wana do expremiental things so just create a branch so that it doent effect the working project once this expreiment is succesfull then merger this branch by pull request .

1. to create branch 
	git checkout -b branchName

2. to chek all branches use 
	git branch

3. to swtich between branches use 
	git checkout branchName

4. to delte branch use 
	git branch -d branchName

5. to save in barnch first follow steps
	git add .
	git commit -m "title" -m "descrption"
	git push origin CurrentbranchName

6. now on github use  create pull request , them merge reques. all branch data will merge to your working branch i.e master


7. all merger call will not reflect to your master after pull and merger on github we also need  to pull on our loacl machine so use

	git pull origin master.

NOTE to check the diffence in currrent brach and master we use 
	git diff 



________________________________________confilctss
(multiple baranches may work on same files so let suppose i writen code on second line other also try to written and commiting but when we merge all branches with master this will create conficts so for this we have to manage as mention beloow)

to check diffrence btween two branches

	git diff OtherBranchName 
	 (current is automaticly picke just give second branch whose code we want to compare)

	then try this 
		git merge branchName  

here conflict will occure if in both files we are trying to written we have to solve manualty by setting code here.

  in collaborative coding ( alwys use git merge branchName after sometime so that you can get less conflict and will carry lates code in your braches)


______________---how to undo commits if we did wrong

git reset HEAD~1  (HEAD refers to last commits 1 means last 1 commit undo krdoe)

git reset --hard "code"  (to get code of commit we want to undo just do git log  ) and copy that code of commit.
