 ## Configuring the ~/.m2/settings.xml file for local development
-In order to be able to pull all the necessary project dependencies, the alfresco Maven
-repositories should be configured in your local `~/.m2/settings.xml` file on your workstation.
+In order to be able to pull all the necessary project dependencies, the alfresco Nexus
+repositories should be added in your local Maven configuration on your workstation.
 
-The necessary `<repository/>` and `<pluginRepository/>` configuration is available in the
-[.travis.settings.xml](.travis.settings.xml) file (_alfresco-internal_ profile),
-which is used by the project 's CI pipeline.
-Just copy the **alfresco-internal** profile into your own `~/m2/repository.xml`.
-You will also need to define an `alfresco-internal` server, but with your own Alfresco Nexus
-credentials.
+Update your `~/.m2/settings.xml` file with the _repositories_, _pluginRepositories_ and, optionally,
+the _servers_ defined in the following snippet:
+```xml
+<settings>
+   <profiles>
+      <profile>
+         <id>alfresco-internal</id>
+         <activation>
+            <activeByDefault>true</activeByDefault>
+         </activation>
+
+         <repositories>
+            <repository>
+               <id>alfresco-internal</id>
+               <releases>
+                  <enabled>true</enabled>
+               </releases>
+               <snapshots>
+                  <enabled>true</enabled>
+               </snapshots>
+               <name>Alfresco Internal Repository</name>
+               <url>https://artifacts.alfresco.com/nexus/content/groups/internal</url>
+            </repository>
+         </repositories>
+
+         <pluginRepositories>
+            <pluginRepository>
+               <id>alfresco-internal</id>
+               <name>Alfresco Internal Repository</name>
+               <url>https://artifacts.alfresco.com/nexus/content/groups/public</url>
+            </pluginRepository>
+         </pluginRepositories>
+      </profile>
+   </profiles>
+
+   <servers>
+      <server>
+         <id>alfresco-internal</id>
+         <username>${env.MAVEN_USERNAME}</username>
+         <password>${env.MAVEN_PASSWORD}</password>
+      </server>
+   </servers>
+</settings>
+```
+
+The `alfresco-internal` server definition is required by the Alfresco _internal_ repository
+group, and it should use your own Alfresco Nexus credentials. If only the _public_ repository
+group is used (e.g., for the Community build) this server definition can be skipped.
+
+Optionally, you can also re-define the Maven Central repository, to increase the dependency download
+speed (look up dependencies first in Maven Central, then in Alfresco Nexus). Define the
+_Central Repository_ in both the `<repositories/>` and `<pluginRepositories/>` sections before
+the _alfresco-internal_ repository:
+```xml
+<repository>
+   <id>central</id>
+   <name>Central Repository</name>
+   <url>https://repo.maven.apache.org/maven2</url>
+   <layout>default</layout>
+   <snapshots>
+      <enabled>false</enabled>
+   </snapshots>
+</repository>
+```
+
