+
+Curator is the program used to manage collections on the [Art Museum][1]
+website. It is a Java program that you run locally on your computer. It allows
+you to upload, edit, and delete the media and albums that appear on the
+website.
+
+Curator exists as a separate program that your run locally to keep the website
+as light as possible. Things such as image, video, and audio metadata
+processing, thumbnail generation, and file type conversion are handled locally,
+sparing the server hosting Art Museum from having to have any such helper
+programs installed.
+
+Curator uses FTP or SFTP to upload media to the web server. The FTP user needs
+to have write access to the data directory used for [Art Museum][1] in order to
+successfully upload media.
+
+Curator has a build in help system. Just click the question mark (`?`) button in
+any dialog and the built-in help system will open to the page most relavant to
+what you are trying to do.
+
+### Building
+
+Curator uses Gradle as a build system. Thus, building is done with
+`gradle build`. Any required dependencies will be automatically downloaded and
+compiled by Gradle. Generating video thumbnails and converting Apple `.mov`
+files requires the `ffmpeg` command line utility.
+
+Curator has been tested on Linux, FreeBSD, and MacOS. A `.desktop` file (for
+Linux, FreeBSD, etc.) and a script to build a MacOS `.app` file is available
+under the `scripts` directory. Note that installing ffmpeg with Homebrew on
+MacOS does **NOT** automatically add it to the `launchd` `$PATH` environment
+variable. Thus, the `.app` file will not be able to find it unless you manually
+add it.
