When contributing to another's project, it is common for the contribution to be of many commits and involve a discussion with the project's maintainer. This is supported via Radicle patches.

Here we give a brief overview for using patches in our hypothetical car scenario. It turns out instructions containing the power requirements were missing from the project.

$ git checkout -b flux-capacitor-power
$ touch REQUIREMENTS

Here the instructions are added to the project's REQUIREMENTS for 1.21 gigawatts and committed with git.

$ git add REQUIREMENTS
$ git commit -v -m "Define power requirements"
[flux-capacitor-power 3e674d1] Define power requirements
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 REQUIREMENTS

Once the code is ready, we open a patch with our changes.

$ git push rad -o no-sync -o patch.message="Define power requirements" -o patch.message="See details." HEAD:refs/patches
✓ Patch 69e881c606639691330051d7d8f013854f32fb87 opened

 * [new reference]   HEAD -> refs/patches

It will now be listed as one of the project's open patches.
