+## Loading Web Archives
+
+Using [https://replayweb.page](https://replayweb.page), you can select a web archive file from a local
+file or remote URL to load into the site.
+
+Archives loaded by ReplayWeb.page are identified by their unique URL, which can be entered directly or selected from a local file chooser.
+
+### Loading Local Web Archives
+
+Using the `Choose File...` button, you can pick any local archive file to load for replay. 
+The click `Load` to load the file. 
+
+The archive is laoded in the browser directly and *not* uploaded anywhere -- it never leaves your computer!
+
+The archive will be identified by a `file://` URL and is not accessible outside your browser. As expected,
+this URL is not shareable.
+
+{:  .fs-3 .pad .bg-grey-lt-100}
+This behavior is similar to how [Webrecorder Player](https://github.com/webrecorder/webrecorder-player) worked, but happens entirely in the browser. <br>The [ReplayWeb.page App](https://github.com/webrecorder/replayweb.page/releases) is also an option for [opening local files when offline](offline#replaywebpage-as-standalone-desktop-electron-app)
+
+
+### Loading Remote Web Archives
+
+To load a remote archive, simply enter the URL of the archive and click `Load`.
+
+{: .fs-3 .pad .bg-grey-lt-100}
+See [Supported Locations](locations) for details on where archives can be loaded from.
+
+The archive will be downloaded, either fully or [only as needed (if possible)](streaming-archives.md) and presented on the archive page.
+
+The system supports WARC files, as well as several other formats
+
+{:  .fs-3 .pad .bg-grey-lt-100}
+See: [Supported Formats](formats) for more details on supported formats.
+
+
+### Loading Remote Archives from Google Drive
+
+ReplayWeb.page also supports loading archives directly from Google Drive.
+
+ReplayWeb.page can be used to open .warc, .warc.gz files directly from google drive using the following steps.
+
+1. Install [ReplayWeb.page Google Drive Integration](https://gsuite.google.com/u/2/marketplace/app/replaywebpage/160798412227)
+
+2. Navigate to any WARC (.warc, .warc.gz) files or WACZ (Web archive collection) files that you have on google drive.
+
+3. You should see an 'Open With ReplayWeb.page' option at the top.
+
+4. Clicking on this should redirect to ReplayWeb.page and begin loading. Google Drive loaded archives will have a source URL starting with `googledrive://`.
+
+
+### Loading Large Files: Full vs On-Demand Loading
+
+Due to the nature of the WARC format, the entire file must be read on first use to generate an index. 
+
+For WARC files **>25MB**, only the index is initially stored in the browser, and the actual content is loaded 'on-demand',
+when the content is first accessed. This leads to faster loading and saves memory when dealing with large archives.
+
+[Web Archive Collection (WACZ)](web-archive-collection-format) are always loaded on-demand, as no indexing is required.
+The initial archive view should load almost instantly as a result.
+
+If an archive could not be loaded, an error will be displayed instead of the progress.
+Please report any issues encountered via [GitHub Issues](https://github.com/webrecorder/replayweb.page/issues)
+
+<hr>
+Once an archive has successfully loaded, you will be redirected to the archive view from where you can explore the archive.
