Do's and Don'ts

How to select a project to work on?

1. Activity on a given project can be observed by looking at when the last commit was made.
2. In case issues and pull requests are pending from long time, better skip that project as likelihood of being accepted is dismal. It is recommended to focus on hot cakes.

Project founder/contributer marked my post as spam

Ask yourself before making submissions:-

1. My changes before commit are properly commented
2. Am I making right commentary about the change and politely requesting for a review?
3. Is my commit message going into PR rightly describe about the change I made?

Ex. Refrain from creating such PR sindresorhus/array-union#8

Guides

I am behind the main repository. How can I create PR now?

I was working on a change on my forked repository but before I can submit my change, main repository merged some changes from elsewhere and now I am not in sync or branch head is running some commits behind the main repository.

It is a common issue generally occur when developers choose to follow develop and release side by side model.

# show branches
$ git branch -v

# show remote sources
$ git remote -v

# add a new source stream
$ git remote add <name ex. upstream> <repository link ex. main repository link>

# check again
$git remote -v
 
# pull code from main repository
$ git pull <source name ex. upstream> <branch name generally same as current working branch>

# if changes are already commited, check logs
$ git log
# Here our commit must be on top.

# push changes
# git push <source name> <branch name>
ex.
$ git push origin master

# Now you can raise PR from web ui
