-## Guide
-### Travis Setup
+This example repository shows how Codecov can be integrated with a simple java-maven project. It uses **GitHub Actions** and **CircleCI** as CI/CD providers and **Jacoco** as the coverage provider.
 
-Add to your `.travis.yml` file.
-```yml
-language: java
+For more information, please see the links below.
 
-# Cobertura is not supported in JDK11 so you must downgrade the JDK that Travis uses if you want to use Cobertura with Travis.
-# See https://github.com/cobertura/cobertura/issues/381
-jdk:
-  - openjdk8
-
-script: "mvn cobertura:cobertura"
-
-after_success:
-  - bash <(curl -s https://codecov.io/bash)
-```
-### Produce Coverage Reports
-#### Add Cobertura plugin
-```xml
-<plugin>
-    <groupId>org.codehaus.mojo</groupId>
-    <artifactId>cobertura-maven-plugin</artifactId>
-    <version>2.7</version>
-    <configuration>
-        <formats>
-            <format>html</format>
-            <format>xml</format>
-        </formats>
-        <check />
-    </configuration>
-</plugin>
-```
-Call `mvn cobertura:cobertura` during your CI tests, [see here](https://github.com/codecov/example-java-maven/blob/master/.travis.yml#L4)
-
-## Caveats
-### Private Repos
-Add to your `.travis.yml` file.
-```yml
-after_success:
-  - bash <(curl -s https://codecov.io/bash) -t uuid-repo-token
-```
