 ## Fixing issues and working stories

 Review the [issues list](https://github.com/hyperledger/fabric/issues) and find
-something that interests you. You could also check the ["help
-wanted"](https://github.com/hyperledger/fabric/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22)
-and ["good first
-bug"](https://github.com/hyperledger/fabric/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-bug)
-lists. It is wise to start with something relatively straight forward and
-achievable. Usually there will be a comment in the issue that indicates whether
-someone has already self-assigned the issue. If no one has already taken it,
-then add a comment assigning the issue to yourself, eg.: `I'll work on this
-issue.`. Please be considerate and rescind the offer in comments if you cannot
-finish in a reasonable time, or add a comment saying that you are still actively
-working the issue if you need a little more time.

 After you have familiarized yourself with `Gerrit`, and maybe played around with
-the `lf-sandbox` project, you should be ready to set up your local [development
-environment](dev-setup/devenv.md). We use a Vagrant-based approach to
-development that simplifies things greatly.
