About the contribution process

The contribution process follows this well-known diagram :

First time:

Fork and clone

1. Fork this project

   Click on the Fork button

2. Clone the fork on your local machine

	git clone git@github.com:$YOURLOGIN/pixano-elements.git
	# OR
	git clone https://github.com/$YOURLOGIN/pixano-elements.git
	# go to code
	cd pixano-elements

3. Add the original repository as a remote called upstream

	git remote add upstream git@github.com:pixano/pixano-elements.git
	# OR
	git remote add upstream https://github.com/pixano/pixano-elements.git

cd pixano-elements
npm run deps
npm run build

5. Run the demo locally:

npx serve demo

Modify and test the code

1. Check that you are on the right branch and pull upstream changes into your local repository if necessary

	git checkout master
	git pull upstream master
	#If needed: merge
	#If needed: git push origin master

2. Create a new branch to work on

	git checkout -b $MY_BRANCH_NAME

3. Implement/fix your feature, comment your code.

4. Test your modifications locally using the serverless-demo

	npm run build
	npx serve demo

This demo takes your local modifications into account, thanks to a bootstrap step.

If you modified the dependencies, you better clean the project before rebuilding:

	npm run clearall
	npm run deps
	npm run build
	npx serve demo

Create a pull request

5. Add or change the documentation as needed.
6. Commit your modifications using meaningfull comments.
7. Push your branch to your fork

	git push origin $MY_BRANCH_NAME

8. On github, open a pull request from your fork in the correct branch.

   A green button "Compare & pull request" should appear. If not, click on branches button (https://github.com/$YOURLOGIN/pixano-elements/branches) and then click the "New pull request" button corresponding to your contribution branch.

9. Complete the merge request message with a meaningfull title and a comprehensive comment: describe how your work is changing Pixano and what modules are impacted. You could use something like:
