vendor/github.com/nxadm/tail/README.md

+![ci](https://github.com/nxadm/tail/workflows/ci/badge.svg)[![Go Reference](https://pkg.go.dev/badge/github.com/nxadm/tail.svg)](https://pkg.go.dev/github.com/nxadm/tail)
+
+# tail functionality in Go
+
+nxadm/tail provides a Go library that emulates the features of the BSD `tail`
+program. The library comes with full support for truncation/move detection as
+it is designed to work with log rotation tools. The library works on all
+operating systems supported by Go, including POSIX systems like Linux and
+*BSD, and MS Windows. Go 1.9 is the oldest compiler release supported.
+
+A simple example:
+
+```Go
+// Create a tail
+t, err := tail.TailFile(
+	"/var/log/nginx.log", tail.Config{Follow: true, ReOpen: true})
+if err != nil {
+    panic(err)
+}
+
+// Print the text of each received line
+for line := range t.Lines {
+    fmt.Println(line.Text)
+}
+```
+
+See [API documentation](https://pkg.go.dev/github.com/nxadm/tail).
+
+## Installing
+
+    go get github.com/nxadm/tail/...
+
+## History
+
+This project is an active, drop-in replacement for the
+[abandoned](https://en.wikipedia.org/wiki/HPE_Helion) Go tail library at
+[hpcloud](https://github.com/hpcloud/tail). Next to
+[addressing open issues/PRs of the original project](https://github.com/nxadm/tail/issues/6),
+nxadm/tail continues the development by keeping up to date with the Go toolchain
+(e.g. go modules) and dependencies, completing the documentation, adding features
+and fixing bugs.
+
+## Examples
+Examples, e.g. used to debug an issue, are kept in the [examples directory](/examples).

vendor/github.com/onsi/ginkgo/CONTRIBUTING.md

+# Contributing to Ginkgo
+
+Your contributions to Ginkgo are essential for its long-term maintenance and improvement.
+
+- Please **open an issue first** - describe what problem you are trying to solve and give the community a forum for input and feedback ahead of investing time in writing code!
+- Ensure adequate test coverage:
+    - When adding to the Ginkgo library, add unit and/or integration tests (under the `integration` folder).
+    - When adding to the Ginkgo CLI, note that there are very few unit tests.  Please add an integration test.
+- Update the documentation. Ginko uses `godoc` comments and documentation on the `gh-pages` branch.
+  If relevant, please submit a docs PR to that branch alongside your code PR.
+
+Thanks for supporting Ginkgo!
+
+## Setup
+
+Fork the repo, then:
+
+```
+go get github.com/onsi/ginkgo
+go get github.com/onsi/gomega/...
+cd $GOPATH/src/github.com/onsi/ginkgo
+git remote add fork git@github.com:<NAME>/ginkgo.git
+
+ginkgo -r -p   # ensure tests are green
+go vet ./...   # ensure linter is happy
+```
+
+## Making the PR
+ - go to a new branch `git checkout -b my-feature`
+ - make your changes
+ - run tests and linter again (see above)
+ - `git push fork`
+ - open PR 🎉

vendor/github.com/onsi/ginkgo/RELEASING.md

+A Ginkgo release is a tagged git sha and a GitHub release.  To cut a release:
+
+1. Ensure CHANGELOG.md is up to date.
+  - Use `git log --pretty=format:'- %s [%h]' HEAD...vX.X.X` to list all the commits since the last release
+  - Categorize the changes into
+    - Breaking Changes (requires a major version)
+    - New Features (minor version)
+    - Fixes (fix version)
+    - Maintenance (which in general should not be mentioned in `CHANGELOG.md` as they have no user impact)
+1. Update `VERSION` in `config/config.go`
+1. Commit, push, and release:
+  ```
+  git commit -m "vM.m.p"
+  git push
+  gh release create "vM.m.p"
+  git fetch --tags origin master
+  ```
