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.
``` (stderr)
$ git push rad -o no-sync -o patch.message="Define power requirements" -o patch.message="See details." HEAD:refs/patches
✓ Patch e4934b6d9dbe01ce3c7fbb5b77a80d5f1dacdc46 opened

* [new reference] HEAD -> refs/patches
```
It will now be listed as one of the project's open patches.
```
