+### Check
+
+You can run all the local checks with the `./gradlew check` task.
+
+ - Detekt
+ - Ktlint
+ - Unit tests
+
+### Publishing
+
+To be able to publish on Maven Central, you need to create a `local.properties` file 
+at the root of the project with the following properties:
+
+```
+# Maven OSSRH credentials
+ossrhUsername=
+ossrhPassword=
+
+# GPG Signing key info
+signing.keyId=…
+signing.secretKeyRingFile=…
+signing.password=…
+```
