 Snapshots of the development version are available in [Sonatype's snapshots repository](https://s01.oss.sonatype.org/content/repositories/snapshots/).
 
+## Releasing a new version
+
+You can simply [draft a new release on GitHub](https://github.com/Eppo-exp/android-sdk/releases) and then CI will take care of the rest.
+
+For publishing a release locally, instead, follow the steps below.
+
+### Prerequisites
+
+1. [Generate a user token](https://central.sonatype.org/publish/generate-token/) on `s01.oss.sonatype.org`;
+2. [Configure a GPG key](https://central.sonatype.org/publish/requirements/gpg/) for signing the artifact. Don't forget to upload it to the key server;
+3. Make sure you have the following vars in your `~/.gradle/gradle.properties` file:
+    1. `ossrhUsername` - User token username for Sonatype generated in step 1
+    2. `ossrhPassword` - User token password for Sonatype generated in step 1
+    3. `signing.keyId` - GPG key ID generated in step 2
+    4. `signing.password` - GPG key password generated in step 2
+    5. `signing.secretKeyRingFile` - Path to GPG key file generated in step 2
+
+Once you have the prerequisites, follow the steps below to release a new version:
+
+1. Bump the project version in `build.gradle`
+2. Run `./gradlew publish -Prelease` or `./gradlew publish -Psnapshot`
+3. Follow the steps in [this page](https://central.sonatype.org/publish/release/#credentials) to promote your release
