Laravel fresh install and git pull, but get error: Untracked working tree file

I installed a fresh copy of Laravel with:

composer create-project --prefer-dist laravel/laravel:5.2.* mylaravelfolder

Then I want to pull a Laravel project I saved in Bitbucket:

cd mylaravelfolder
git init
git remote add origin http://ift.tt/2r9VQLg
git fetch --all
git pull origin master

I get:

error: Untracked working tree file '.env.example' would be overwritten by merge.

I can see the list of untracked files with:

git status

How can I ignore those files and overwrite them with mylaravelproject.git? I read I could do this but wouldn't git add . mess my mylaravelproject.git on Bitbucket?

git add .
git stash
git pull
