+### Merge request diffs
+
 When refreshing a Merge Request (pushing to a source branch, force-pushing to target branch, or if the target branch now contains any commits from the MR)
 we fetch the comparison information using `Gitlab::Git::Compare`, which fetches `base` and `head` data using Gitaly and diff between them through
 `Gitlab::Git::Diff.between` (which uses _Gitaly_ if it's enabled, otherwise _Rugged_).

+### Note diffs
+
+When commenting on a diff (any comparison), we persist a truncated diff version
+on `NoteDiffFile` (which is associated with the actual `DiffNote`). So instead
+of hitting the repository every time we need the diff of the file, we:
+
+1. Check whether we have the `NoteDiffFile#diff` persisted and use it
+2. Otherwise, if it's a current MR revision, use the persisted

 As explained above, we limit single diff files and the size of the whole diff. There are scenarios where we collapse the diff file,

+## Testing with older browsers
+
+Some regressions only affect a specific browser version. We can install and test in particular browsers with either Firefox or Browserstack using the following steps:
+
+
+### Browserstack
+
+[Browserstack](https://www.browserstack.com/) allows you to test more than 1200 mobile devices and browsers. 
+You can use it directly through the [live app](https://www.browserstack.com/live) or you can install the [chrome extension](https://chrome.google.com/webstore/detail/browserstack/nkihdmlheodkdfojglpcjjmioefjahjb) for easy access.
+You can find the credentials on 1Password, under `frontendteam@gitlab.com`.
+
+### Firefox
+
+#### macOS
+You can download any older version of Firefox from the releases FTP server, https://ftp.mozilla.org/pub/firefox/releases/
+
+1. From the website, select a version, in this case `50.0.1`.
+2. Go to the mac folder.
+3. Select your preferred language, you will find the dmg package inside, download it.
+4. Drag and drop the application to any other folder but the `Applications` folder.
+5. Rename the application to something like `Firefox_Old`.
+6. Move the application to the `Applications` folder.
+7. Open up a terminal and run `/Applications/Firefox_Old.app/Contents/MacOS/firefox-bin -profilemanager` to create a new profile specific to that Firefox version.
+8. Once the profile has been created, quit the app, and run it again like normal. You now have a working older Firefox version.

+
+The Web IDE can be used to preview JavaScript projects right in the browser.
+This feature uses CodeSandbox to compile and bundle the JavaScript used to
+preview the web application. On public projects, an `Open in CodeSandbox`
+button is visible which will transfer the contents of the project into a
+CodeSandbox project to share with others.
+**Note** this button is not visible on private or internal projects.
+
+![Web IDE Client Side Evaluation](img/clientside_evaluation.png)

+### Enabling Client Side Evaluation
+
+The Client Side Evaluation feature needs to be enabled in the GitLab instances
+admin settings. Client Side Evaluation is enabled for all projects on
+GitLab.com
+
+![Admin Client Side Evaluation setting](img/admin_clientside_evaluation.png)
+
+Once it has been enabled in application settings, projects with a
