     See the \l {Bodymovin Source}{GitHub page for Bodymovin} for instructions
     on how to download and install the plugin for Adobe After Effects.
 
+    \section1 Limitations
+
+    The implementation follows the \l {Bodymovin Specification}{master specification for bodymovin}.
+    Deviations in exported Bodymovin files compared to the specification are
+    taken into account as much as possible when differences are noticed.
+
+    \section2 General limitations
+
+    \list
+    \li \c precomps are not supported
+    \li expressions are not supported
+    \li the timeline only supports frame-mode, not time-mode
+    \endlist
+
+    \section2 Animation level limitations
+
+    The following properties are not supported:
+
+    \list
+    \li \c assets - reusable text and images
+    \li \c chars text
+    \endlist
+
+    \section2 Layers
+
+    Only the \c shape layer and the \c {alpha mask adjustment} layer are supported.
+
+    The following properties are not supported:
+
+    \list
+    \li \c ao (auto-orientation)
+    \li \c bm (blend mode)
+    \li \c maskProperties (masks)
+    \li \c sr (time stretch)
+    \endlist
+
+    \section2 Shapes
+
+    The following elements and shapes are not supported:
+
+    \list
+    \li the \c gstroke (group stroke) element
+    \li the \c star element
+    \li Nested Repeater shapes
+    \endlist
+
+    Also note that the behavior when using multiple active trim paths (e.g. trim
+    paths in nested groups) is unpredictable.
+
+    \section2 Effects
+
+    The only supported effects are \c Slide and \c {Layer Fill}.
+
     \section1 Licenses
 
     Qt Lottie Animation is available under commercial licenses from \l{The Qt Company}.
