+#### Signing
+
+To configure jar signing, you need to have a gpg key.
+
+* Get public key ID `gpg --list-keys --keyid-format SHORT`
+* Export key `gpg --keyring secring.gpg --export-secret-keys > ~/.gnupg/secring.gpg`
+* Add the following properties to `~/.gradle/gradle.properties`
+
+```properties
+signing.keyId=<KEY-ID>
+signing.password=<PASSWORD>
+signing.secretKeyRingFile=<HOME-DIR>/.gnupg/secring.gpg
+```
+
+#### Upload archives
+
+Add the following properties to `~/.gradle/gradle.properties` (same credentials as for https://oss.sonatype.org):
+
+```properties
+ossrhUsername=<USERNAME>
+ossrhPassword=<PASSWORD>
+```
+
+Alternatively, you can pass the credentials as command line parameters:
+
+```sh
+./gradlew release --info -PossrhUsername=<USERNAME> -PossrhPassword=<PASSWORD>
 ```
