with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# otelhttp

This is a copy from [opentelemetry-go-contrip](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation)
This is a copy from [opentelemetry-go-contrib](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation)

The README there says, in part

> The last place instrumentation should be hosted is here in this repository. Maintaining instrumentation here hampers the development of OpenTelemetry for Go and therefore should be avoided.

There have been multiple PRs to improve the net/http instrumentation
that have not been merged for months and so, in typical go fashion, we
have to re-implement it ourselves.

[otelhttp](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation/net/http/otelhttp)

as of [v.0.26.1](https://github.com/open-telemetry/opentelemetry-go-contrib/commit/7876cd14dc5f09765205caa0fb420fafe23141aa)

Can you add setup instructions? Especially for non-nix users since they'll have to make sure go and pre-commit are set up correctly. Well even nix users will need to install pre-commit hooks.

I added a blurb to the README

This copy does not create separate packages for the test and
example code, and so did not copy the `go.{mod,sum}` files from those
directories.


## Setup

1. You will need go and pre-commit installed
1. run `pre-commit install && pre-commit install-hooks`

### Running the tests

go test ./...

### Checking CI

Install [act](https://github.com/nektos/act)
