-The following key/values may be defined in the properties file or as environment variables:
+== Maven
 
-== Project
+JReleaser will honor Maven project properties. These properties can be defined in several ways:
+
+- on the command line by using the `-D` flag.
+- on a `pom.xml` by using the `<properties>` block.
+- on a settings file using the `<properties>` block inside an active profile.
+
+JReleaser should be able to handle properties define in any of these ways.
+Precedence is:
+
+- values defined in the model.
+- values defined as Maven properties.
+- values defined in `<releaser><environment><variables>`.
+- environment variables.
+
+Keys must either be fully uppercase words separated by underscores (`_`) or fully lowercase words separated by dots (`.`).
+The uppercase variant has precedence over the lowercase variant. For example, the Github token may be defined in
+`~/.m2/settings.xml` as:
+
+[source,xml]
+[subs="verbatim"]
+.settings.xml

+== Gradle
+
+JReleaser will honor Gradle project properties. These properties can be defined in several ways:
+
+- on the command line by using the `-P` flag.
+- on a `gradle.properties` file adjacent to the project.
+- on a `gradle.properties` file located at `~/.gradle`.
+
+JReleaser should be able to handle properties define in any of these ways.
+Precedence is:
+- values defined in the model.
+- values defined as Gradle project properties.
+- values defined in `jreleaser.environment.variables`.
+- environment variables.
+
+Keys must either be fully uppercase words separated by underscores (`_`) or fully lowercase words separated by dots (`.`).
+The uppercase variant has precedence over the lowercase variant. For example, the Github token may be defined in
+`/.gradle/gradle.properties` as:
+
+[source]
+.gradle.properties
+----
+JRELEASER_GITHUB_TOKEN = 2ee1ce8ff570e0bOVEdrZvie8792058
