  - Submit your changes early and often. Input and
    corrections early in the process prevent huge changes later.
 
- - Please open a ticket in the Aether Jira describing the issue/feature. During the patch please
-   preface the commit message with `[AETHER-<jira_number]` e.g. `[AETHER-3400]` so it gets
-   automatically linked to the Jira ticket. This keeps code review and design discussions clean.
+ - It is good practice to open a ticket in the `Aether Jira
+   <https://lf-aether.atlassian.net/jira/your-work>`__ describing the

-Steps to Successful PRs (gerrit workflows)
-""""""""""""""""""""""""""""""""""""""""""
-
- 1. Checkout the code and prepare your patch. The workflow to make changes to the Aether code through gerrit is identical
-    to the one from `onos-classic` and is described in the
-    `Sample Gerrit Workflow page <https://wiki.onosproject.org/display/ONOS/Sample+Gerrit+Workflow>`_
-
- 2. Before submitting the patch via `git review` please execute Aether specific tests:
-    `make test` and `make linters`. These commands run unit test, linting and other elements
-    to assure the quality of your patch.
-
- 3. Wait for Jenkins sanity checks to pass.
-    If the tests fail please fix your patch and then repeat 2 and 3, as necessary.
-    **Passing CI verification is mandatory.** If the CI check does not start or fails but you think the issue
-    is unrelated you can re-trigger by commenting on to the patch with `recheck`.
-
- 4. When comments are made to your patch please make the appropriate fixes and then
-    amend your commit with `git commit --amend` and re-upload to gerrit with `git review`.
-
- 5. Await review. Everyone can comment on code changes, but only Collaborators
-    and Core contributors can give final review approval. **All changes must get at least one
-    approval**.

  4. Using the Github user interface on your fork, open a pull request. Add a reviewer from

     it helps to be involved in informal conversation with a reviewer.
