 If you find a bug that you'd like to fix, or a new feature that you'd
 like to implement then please submit a pull request via GitHub.
 
-If it is a big feature, then [make an issue](https://github.com/rclone/rclone/issues) first so it can be discussed.
+If it is a big feature then make an issue first so it can be discussed.
 
-To prepare your pull request first press the fork button on [rclone's GitHub
+You'll need a Go environment set up with GOPATH set.  See [the Go
+getting started docs](https://golang.org/doc/install) for more info.
+
+First in your web browser press the fork button on [rclone's GitHub
 page](https://github.com/rclone/rclone).
 
-Then [install Git](https://git-scm.com/downloads) and set your public contribution [name](https://docs.github.com/en/github/getting-started-with-github/setting-your-username-in-git) and [email](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/setting-your-commit-email-address#setting-your-commit-email-address-in-git).

-## Using Git and Github ##
+## Enabling CI for your fork ##
 
-### Committing your changes ###
+The CI config files for rclone have taken care of forks of the project, so you can enable CI for your fork repo easily.
 
-Follow the guideline for [commit messages](#commit-messages) and then:
-
-    git checkout my-new-feature      # To switch to your branch
-    git status                       # To see the new and changed files
-    git add FILENAME                 # To select FILENAME for the commit
-    git status                       # To verify the changes to be committed

-    git log                          # To verify the commit. Use q to quit the log
-
-You can modify the message or changes in the latest commit using:
-
-    git commit --amend
-
-If you amend to commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Replacing your previously pushed commits ###
-
-Note that you are about to rewrite the GitHub history of your branch. It is good practice to involve your collaborators before modifying commits that have been pushed to GitHub.
-
-Your previously pushed commits are replaced by:
-
-    git push --force origin my-new-feature 
-
-### Basing your changes on the latest master ###
-
-To base your changes on the latest version of the [rclone master](https://github.com/rclone/rclone/tree/master) (upstream):
-
-    git checkout master
-    git fetch upstream
-    git merge --ff-only
-    git push origin --follow-tags    # optional update of your fork in GitHub
-    git checkout my-new-feature
-    git rebase master
-
-If you rebase commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Squashing your commits ###
-
-To combine your commits into one commit:
-
-    git log                          # To count the commits to squash, e.g. the last 2
-    git reset --soft HEAD~2          # To undo the 2 latest commits
-    git status                       # To check everything is as expected
-
-If everything is fine, then make the new combined commit:
-
-    git commit                       # To commit the undone commits as one
-
-otherwise, you may roll back using:
-
-    git reflog                       # To check that HEAD{1} is your previous state
-    git reset --soft 'HEAD@{1}'      # To roll back to your previous state
-
-If you squash commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-Tip: You may like to use `git rebase -i master` if you are experienced or have a more complex situation.
-
-### GitHub Continuous Integration ###
-
-rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions) to build and test the project, which should be automatically available for your fork too from the `Actions` tab in your repository.
+rclone currently uses [Travis CI](https://travis-ci.org/), [AppVeyor](https://ci.appveyor.com/), and
+[Circle CI](https://circleci.com/) to build the project. To enable them for your fork, simply go into their
+websites, find your fork of rclone, and enable building there.

 ## Making a point release
 
 If rclone needs a point release due to some horrendous bug:
 
-Set vars
-
-  * BASE_TAG=v1.XX          # e.g. v1.52
-  * NEW_TAG=${BASE_TAG}.Y   # e.g. v1.52.1
-  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
-
 First make the release branch.  If this is a second point release then
 this will be done already.
 
-  * git branch ${BASE_TAG} ${BASE_TAG}-stable
-  * git co ${BASE_TAG}-stable
-  * make startstable
+  * BASE_TAG=v1.XX          # eg v1.49

+  * echo $BASE_TAG $NEW_TAG # v1.49 v1.49.1
+  * git branch ${BASE_TAG} ${BASE_TAG}-fixes
 
 Now
 
-  * git co ${BASE_TAG}-stable

   * git cherry-pick any fixes
-  * Do the steps as above
-  * make startstable
+  * Test (see above)
