   1.6 What do you get for making curl?
 
-  Project cURL is entirely free and open. No person gets paid for developing
-  curl full time. We do this voluntarily, mostly in our spare time.
-  Occasionally companies pay individual developers to work on curl, but that's
-  up to each company and developer. This is not controlled by nor supervised in
-  any way by the project.

-  We still get help from companies. Haxx provides website, bandwidth, mailing
-  lists etc, GitHub hosts the primary git repository and other services like
-  the bug tracker at https://github.com/curl/curl. Also again, some companies
-  have sponsored certain parts of the development in the past and I hope some
-  will continue to do so in the future.

   1.11 Why don't you update ca-bundle.crt
 
-  The ca cert bundle that used to be shipped with curl was very outdated and
-  must be replaced with an up-to-date version by anyone who wants to verify

   1.14 How do I submit my patch?
 
-  When you have made a patch or a change of whatever sort, and want to submit
-  that to the project, there are a few different ways we prefer:
+  We strongly encourage you to submit changes and improvements directly as
+  "pull requests" on github: https://github.com/curl/curl/pulls
 
-  o send a patch to the curl-library mailing list. We're many subscribers
-    there and there are lots of people who can review patches, comment on them
-    and "receive" them properly.
-
-  o if your patch changes or fixes a bug, you can also opt to submit a bug
-    report in the bug tracker and attach your patch there. There are less
-    people involved there.
+  If you for any reason can't or won't deal with github, send your patch to
+  the curl-library mailing list. We're many subscribers there and there are
+  lots of people who can review patches, comment on them and "receive" them
+  properly.
 
   Lots of more details are found in the CONTRIBUTE and INTERNALS docs.
