-Automatic setup:
-
-* Run ``scripts/macos-setup-codesign.sh``
-
-Manual setup steps:
-
-* Launch /Applications/Utilities/Keychain Access.app
-* In Keychain Access select the ``login`` keychain in the ``Keychains`` list in
-  the upper left hand corner of the window.
-* Select the following menu item: Keychain Access->Certificate Assistant->Create a Certificate...
-* Set the following settings
-
-::
-
-	Name = lldb_codesign
-	Identity Type = Self Signed Root
-	Certificate Type = Code Signing
-
-* Click Create
-* Click Continue
-* Click Done
-* Click on the "My Certificates"
-* Double click on your new ``lldb_codesign`` certificate
-* Turn down the "Trust" disclosure triangle, scroll to the "Code Signing" trust
-  pulldown menu and select "Always Trust" and authenticate as needed using your
-  username and password.
-* Drag the new ``lldb_codesign`` code signing certificate (not the public or
-  private keys of the same name) from the ``login`` keychain to the ``System``
-  keychain in the Keychains pane on the left hand side of the main Keychain
-  Access window. This will move this certificate to the ``System`` keychain.
-  You'll have to authorize a few more times, set it to be "Always trusted" when
-  asked.
-* Remove ``~/Desktop/lldb_codesign.cer`` file on your desktop if there is one.
-* In the Keychain Access GUI, click and drag ``lldb_codesign`` in the
-  ``System`` keychain onto the desktop. The drag will create a
-  ``Desktop/lldb_codesign.cer`` file used in the next step.
-* Switch to Terminal, and run the following:
-
-::
-
-  sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer
-  rm -f ~/Desktop/lldb_codesign.cer
-
-* Drag the ``lldb_codesign`` certificate from the ``System`` keychain back into
-  the ``login`` keychain
-* Quit Keychain Access
-* Reboot
-* Clean by removing all previously creating code signed binaries and rebuild
-  lldb and you should be able to debug.

 When you build your LLDB for the first time, the Xcode GUI will prompt you for
 permission to use the ``lldb_codesign`` keychain. Be sure to click "Always
 Allow" on your first build. From here on out, the ``lldb_codesign`` will be
