+## Versioning
+
+This library uses [Nerdbank.GitVersioning](https://github.com/AArnott/Nerdbank.GitVersioning) for generating stable and reproducible version numbers.
+
+The base version is manually maintained in [the version config](version.json). Every build calculates its final version number based on the base version and the number of changes that occured since the last change to the version config.
+
+The base version represents the MAJOR and MINOR parts of [SemVer](https://semver.org). If a PR contains breaking changes or new features the base version has to be changed accordingly. If a PR solely contains minor changes (bug fixes, code improvements) nothing needs to be done as the PATCH number will automatically increment with each commit.
+
+## Branches / tags
+
+* `master` contains the latest sources - this is where we develop.
+* `release` contains the sources for the latest version on `nuget.org` - this is where we deploy from.
+* All versions on `nuget.org` have a matching GitHub release/tag
+
+### Release workflow
+
+1. Create a [PR from `master` to `release`](https://github.com/System-IO-Abstractions/System.IO.Abstractions/compare/release...master?expand=1) and wait for CI to finish. 
+1. Inspect CI run (test results, version number)
+1. Merge PR and wait for deployment
+1. Inspect newly created package versions on NuGet.org and newly created GitHub release
