 * Merge the edits but be sure to remove the history of your local commits via `git merge --squash <temp_branch>` (replacing `<temp_branch>` with the branch name you used earlier)
 * Create a new commit containing all of your merged changes via `git commit -m "<Message>"` (replacing `<Message>` with information regarding the contents of your changes)

+GitHub provides a drop-down option to apply a PR as a "Squash and Merge", directly from the PR.  GitHub even supports [configuring the depot](https://github.com/dotnet/runtime/issues/260#issuecomment-649622840) such that PRs *must* be "Squash and Merge".  See picture at end of page.
+
+However, if you're requested to manually squash and merge **before** the PR is reviewed and approved, you can create a second branch on GitHub and perform the squash and merge entirely via the website:
+
+_Note: for legacy depots, instead of the branch name 'main', you may see a branch name of 'master'._

+
+* goto your fork of the depot on github.com
+* ensure you are viewing the branch 'main'
+* select the "fetch upstream" button, then "fetch and merge"
+
+</details>
+<details><summary>2. Create a new branch based off your main branch</summary><P/>
+
+* goto your fork of the depot on github.com
+* ensure you are viewing the branch 'main'
+* click on the branch name
+* Type a name for your new branch; I'll use the branch name `foo` in this example
+* click on the `create branch: foo from 'main'` that appears after you type the name
+

+<details><summary>3. Create a PR to this new branch</summary><P/>
+
+* goto your fork of the depot on github.com
+* select the `pull requests` tab (on your fork ... not the upstream depot)
+* select `New pull request` button
+* the `base repository` will default to the upstream depot; change it to your fork
+* _**note the UI is now much simpler :smiley:**_
+* for the `base` branch, select the newly created branch (e.g., `foo`)
+* for the `compare` branch, select the old PR branch (e.g., `oldPR`)
+* click the resulting `Create pull request` button
+* Give the PR a title and a comment
+* Click to "submit" the PR to yourself...
+
+</details>
+<details><summary>4. Approve your own PR, but select the option "Squash and Merge"</summary><P/>
+
+* Scroll down a bit
+* Choose the down-triangle on the right side of the `Merge pull request` big green button
+* From the drop-down options, select `Squash and merge`
+* Now click the big green button that says `Squash and Merge`
+* Edit the description as you like ... this will become the commit message
+* Click the big green button that says `Confirm squash and merge`
