Problem

The READMEs came in from the separate repositories and still carried what those
repositories had.

• Logo. The root README showed .github/images/logo.png. Every package
  README showed the 51Degrees wordmark from https://51degrees.com/img/logo.png,
  with campaign parameters on the image URL, and fiftyone.pipeline.did
  showed none.
  51degrees-dotnet#75
  found that nuget.org renders images only from
  an allowed list of hosts
  that 51degrees.com is not on, so the .NET package pages showed no logo at
  all, and .NET, PHP, Go and Rust all moved to the repository's own mark
  served from raw.githubusercontent.com. How npmjs.com renders the old URL
  was not checked for this change, because the reason to move is to show the
  same mark as the other four languages wherever the README is read.
• Contributing. There was no contributing guide anywhere in the repository.
• Links. The Developer Documentation link at the top of each package
  README, which a package page shows, went to the main page of that package's
  generated API reference, for example
  https://51degrees.com/ip-intelligence-node/index.html, which has no
  content. The root README's table linked the same kind of page for each of the
  four products. Two READMEs linked a dependencies page that now redirects to
  the documentation home page.

.NET, PHP, Go and Rust have all taken this change, so a reader of a Node
package README met a different mark and an empty documentation page where the
same package in another language showed the repository's mark and the quick
start.

Change

• .github/images/logo-160.png is a 160 pixel copy of .github/images/logo.png,
  the size the root README shows it at. Every package README, and the two
  run_examples.md files, now shows it as a Markdown image from
  raw.githubusercontent.com, which is the host the other four languages
  moved to.
  fiftyone.pipeline.did, which had no logo, gains it below its title. The
  image URL carries no campaign parameters, because it is not a 51degrees.com
  link.
• CONTRIBUTING.md at the root links the
  51Degrees contributing guide
  and says it applies to every package in this repository. The wording is the
  same five lines .NET, PHP and Go use.
• Each package README's Developer Documentation link now goes to the product's
  quick start or concepts page on 51degrees.com rather than to the empty
  reference index, and the root README's table gives both the guide and the
  Node.js API reference for each of the four products.
• The two links to the dependencies page are removed, because that page
  redirects to the documentation home. The tested versions link beside it
  stays.

Every link keeps the five campaign parameters in the order
scripts/utm-lint.ps1 enforces, with utm_source=npm and utm_medium=package
in a package README, utm_source=github and utm_medium=readme in the root
and folder READMEs and utm_medium=docs in the two run_examples.md files,
and utm_term changed where the destination changed.

The same change in the other languages

Language	Pull request
.NET	#75
PHP	#36
Go	#58
Rust	#277

The CONTRIBUTING.md here is byte for byte the one
51degrees-dotnet#75
added, and the logo URL has the same shape, pointing at main in this
repository. Java #49 and
Python #46 carry it for
those two languages and are not mine.

Tests

Documentation only. No code changes, so there is no test to fail first and no
red run. This draft's own
utm-link-lint check
passes, which is the check that reads the campaign parameters on every link
this touches.

Full build. Run 43023120786,
on tmp/pr-matrix-33, success. Every one of its seven
Setting 'PullRequestSha' lines reads
6d0fa27df31abe4ac0b09c49babaec9bd4a06ffd, which is this head. Configure
printed "Left out 2 macOS entries". The branch it built from was rc at
8b9fc3d, and rc has moved on since. Nothing rc has taken since touches a
README, and the draft merges into the current rc with no conflict.

macOS was left out of this draft's full build under the 9 November decision.
The rc head is built with macOS before it merges into main.

What remains

The logo URL points at .github/images/logo-160.png on main, and this change
is what adds that file, so the image resolves once the change reaches main.
.NET, PHP and Go all point at main in their own repositories in the same way.
A reader on GitHub sees the image from this branch, and a reader of a published
package sees it from the first release after the merge.
