+## Preparing release
+
+_TBD_
+
+## Trusting TrueCloudLab code signing CA certificate
+
+Verifying signatures (and signing) TrueCloudLab packages requires adding
+[TrueCloudLab Code Signing CA](ca.cert) to the list of trusted roots.
+
+On Linux this can be done by appending [release/ca.cert](ca.cert) to one of:
+
+- `/etc/pki/ca-trust/extracted/pem/objsign-ca-bundle.pem`: compatible with
+  [update-ca-trust] and originally proposed in [.NET design docs]
+- `…/dotnet/sdk/X.Y.ZZZ/trustedroots/codesignctl.pem`: [fallback] codesigning certificate trust list for .NET
+
+[update-ca-trust]: https://www.linux.org/docs/man8/update-ca-trust.html
+[.NET design docs]: https://github.com/dotnet/designs/blob/main/accepted/2021/signed-package-verification/re-enable-signed-package-verification-technical.md#linux
+[fallback]: https://github.com/dotnet/sdk/blob/11150c0ec9020625308edeec555a8b78dbfb2aa5/src/Layout/redist/trustedroots/README.md
+
+## Signing Nuget packages
+
+Repository maintainer places `maintainer.cert` and `maintainer.key` (see below
+regarding obtaining these files) into `release/` directory and then
+executes:
+
+```console
+$ make build sign
+```
+
+## Uploading packages to Nuget registry
+
+**IMPORTANT: the following steps upload all `*.nupkg` files located under
+`src/`. Maintainer MUST make sure that no unnecessary package versions will be
+uploaded to the registry.**
+
+Configure registry credentials (once per machine):
+
+```console
+$ make nuget-registry NUGET_REGISTRY_USER=username NUGET_REGISTRY_PASSWORD=token
+```
+
+Publish all locally built packages (implicitly clear existing `*.nupkg` and
+rebuild current version only):
+
+```console
+$ make clean build sign publish
+```
+
+
+## Obtaining release signing certificate
+
+Repository maintainer owns and keeps safe the release signing key
+(`maintainer.key`). Private key should never leave maintainer's machine and
+should be considered a highly sensitive secret.
+
+- Generating new maintainer key and the corresponding CSR:
+
+  ```console
+  $ make maintainer.csr
+  ...lines skipped...
+  Enter PEM pass phrase:
+  Verifying - Enter PEM pass phrase:
+  -----
+  IMPORTANT: Keep maintainer.key private!
+
+  Certificate signing request is ready.
+  Send maintainer.csr to CA administrator to obtain the certificate.
+  ```
+
+  Resulting CSR (`maintainer.csr`) does not contain any sensitive
+  cryptographic material and may be passed to CA administrator through regular
+  communication channels.
+
+- CA administrator then issues the certificate (`make maintainer.cert`) and
+  sends it back to the maintainer to be used in combination with
+  `maintainer.key`
+
+This procedure should be repeated once per machine per `maintainer.cert`
+lifetime (1 year) - typically just once per year since we expect the
+maintainer to use only a single computer to sign releases.
