The buildroot repository can be browsed online at https://gitlab.com/buildroot.org/buildroot/.
To grab a copy of the repository use
If you are not already familiar with using Git, we recommend you visit the Git website.
Once you've checked out a copy of the source tree, you can update your source tree at any time so it is in sync with the latest and greatest by entering your buildroot directory and running the command:
git pull
Because you've only been granted anonymous access to the tree, you won't be able to push your changes to the repo. Changes can instead be submitted for inclusion by posting them to the buildroot mailing list.
