-## Using Git and Github ##
-
-### Committing your changes ###
-
-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 commit                       # To do the commit
-    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 ###
+## CI for your fork ##
