+Apache Zipkin Brave (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
+Incubation is required of all newly accepted projects until a further review indicates 
+that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. 
+While incubation status is not necessarily a reflection of the completeness or stability of the code, 
+it does indicate that the project has yet to be fully endorsed by the ASF.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

-# Brave Release Process
-
-This repo uses semantic versions. Please keep this in mind when choosing version numbers.
-
-1. **Alert others you are releasing**
-
-   There should be no commits made to master while the release is in progress (about 10 minutes). Before you start
-   a release, alert others on [gitter](https://gitter.im/openzipkin/zipkin) so that they don't accidentally merge
-   anything. If they do, and the build fails because of that, you'll have to recreate the release tag described below.
-
-1. **Push a git tag**
-
-   The tag should be of the format `release-N.M.L`, for example `release-3.7.1`.
-
-1. **Wait for Travis CI**
-
-   This part is controlled by [`travis/publish.sh`](travis/publish.sh). It creates a bunch of new commits, bumps
-   the version, publishes artifacts, and syncs to Maven Central.
-
-## Credentials
-
-Credentials of various kind are needed for the release process to work. If you notice something
-failing due to unauthorized, re-encrypt them using instructions at the bottom of the `.travis.yml`
-
-Ex You'll see comments like this:
-```yaml
-env:
-  global:
-  # Ex. travis encrypt BINTRAY_USER=your_github_account
-  - secure: "VeTO...
-```
-
-To re-encrypt, you literally run the commands with relevant values and replace the "secure" key with the output:
-
-```bash
-$ travis encrypt BINTRAY_USER=adrianmole
-Please add the following to your .travis.yml file:
-
-  secure: "mQnECL+dXc5l9wCYl/wUz+AaYFGt/1G31NAZcTLf2RbhKo8mUenc4hZNjHCEv+4ZvfYLd/NoTNMhTCxmtBMz1q4CahPKLWCZLoRD1ExeXwRymJPIhxZUPzx9yHPHc5dmgrSYOCJLJKJmHiOl9/bJi123456="
-```
-
-### Troubleshooting invalid credentials
-
-If you receive a '401 unauthorized' failure from jCenter or Bintray, it is
-likely `BINTRAY_USER` or `BINTRAY_KEY` entries are invalid, or possibly the user
-associated with them does not have rights to upload.
-
-The least destructive test is to try to publish a snapshot manually. By passing
-the values Travis would use, you can kick off a snapshot from your laptop. This
-is a good way to validate that your unencrypted credentials are authorized.
-
-Here's an example of a snapshot deploy with specified credentials.
-```bash
-$ BINTRAY_USER=adrianmole BINTRAY_KEY=ed6f20bde9123bbb2312b221 TRAVIS_PULL_REQUEST=false TRAVIS_TAG= TRAVIS_BRANCH=master travis/publish.sh
-```
-
-## First release of the year
-
-The license plugin verifies license headers of files include a copyright notice indicating the years a file was affected.
-This information is taken from git history. There's a once-a-year problem with files that include version numbers (pom.xml).
-When a release tag is made, it increments version numbers, then commits them to git. On the first release of the year,
-further commands will fail due to the version increments invalidating the copyright statement. The way to sort this out is
-the following:
-
-Before you do the first release of the year, move the SNAPSHOT version back and forth from whatever the current is.
-In-between, re-apply the licenses.
-```bash
-$ ./mvnw versions:set -DnewVersion=1.3.3-SNAPSHOT -DgenerateBackupPoms=false
-$ ./mvnw com.mycila:license-maven-plugin:format
-$ ./mvnw versions:set -DnewVersion=1.3.2-SNAPSHOT -DgenerateBackupPoms=false
-$ git commit -am"Adjusts copyright headers for this year"

-Check for [instrumentation written here](../) and [Zipkin's list](http://zipkin.io/pages/existing_instrumentations.html)
+Check for [instrumentation written here](../) and [Zipkin's list](https://zipkin.apache.org/pages/existing_instrumentations.html)
 before rolling your own Http instrumentation! Besides documentation here,
 you should look at the [core library documentation](../../brave/README.md) as it
 covers topics including propagation. You may find our [feature tests](src/test/java/brave/http/features) helpful, too.
