+# Annotator
+
+This is a simple tool for annotating (short) videos. It is designed to facilitate frame-level annotations, at the expense of having to load the entire video into memory. Future versions may relax this requirement.
+
+## Building
+
+Requirements are:
+
+ * libconfuse (for parsing config file)
+ * opencv (for video playback)
+
+Compile by running:
+
+```console
+./configure
+make
+```
+
+## Usage
+
+Available labels are configured in `annotator.conf`. Controls are as follows:
+
+ * Number keys: Make annotation
+ * Escape: Quit (doesn't save)
+ * Space: Pause
+ * Left arrow: Go backward 1 frame
+ * Right arrow: Go forward 1 frame
+ * Up arrow: Seek backard 1 second
+ * Down arrow: Seek forward 1 second
+ * u: Undo (WIP)
+ * r: Redo (WIP)
+ * Delete: Remove closest annotation to current frame
+ * s: Save (there is no autosave)
+
