-- Clone the repository using one of the URLs at the bottom of https://git.eclipse.org/c/jsf/webtools.jsf.git/
-- Set up your Gerrit access, including a SSH public key, on https://git.eclipse.org/r/ .
-- Take note of your Username as listed on https://git.eclipse.org/r/settings/ (when logged in).
-- Add a `git remote` for gerrit using `ssh://{username}@git.eclipse.org:29418/jsf/webtools.jsf`
-- Ready your changes
-- You can also run the Maven build, supplying using at least Tycho 4.0.0 for the values in `-Dtycho-extras.version=${tychoVersion} -Dtycho.version=${tychoVersion}` and profile `bree-libs` with `-Pbree-libs`.
-- Create a local "topic" branch and commit your changes.  Please start your commit messages first line with the word "bug" and the bug number, e.g. `Bug 12345` to refer to bug 12345, both to make it more understandable in the eventual git history and to allow Gerrit to automagically link it to the bug report.
-- Push your changes to the Gerrit remote using refspec `HEAD:refs/for/master`
-- You'll be given a URL like https://git.eclipse.org/r/c/jsf/webtools.jsf/+/163278 unique to your changes. Please go there and click on ADD REVIEWER, choosing the [project lead](https://projects.eclipse.org/projects/webtools.jsf/who), so they get notified of your proposal.
-- If you need to make more changes, find the generated Change-Id on your change's page (e.g. `Change-Id: Ibe9f831a614edfe4e637038c4de0c3a849efb329`), and make sure it is copied as the last line in your updated commit message. Then you can push your commit as before and it will have a history in Gerrit on the same page with the same conversations.
+Hints for pull requests:
+- You can run the Maven build with the standard `clean` and `install` goals. Optionally you may specify a Tycho version using `-Dtycho-extras.version=${tychoVersion} -Dtycho.version=${tychoVersion}` (4.0.4 and higher)` and profile `bree-libs` with `-Pbree-libs`.
+- Please refer the GitHub issue in your commit message (e.g #1). If you're fixing an old bug [from Bugzilla](https://bugs.eclipse.org/bugs/), start your commit messages first line with the word "bug" and the bug number, e.g. Bug 12345 to refer to bug 12345 to make it more understandable in the eventual git history.
