+Snap is a cross-distribution packaging format for Linux. See
+https://snapcraft.io for more information.
+
+How to build
+------------
+Just type
+```
+snapcraft
+```
+from the *parent* directory: that is, not from the directory containing this
+README file, but from its parent directory. This snap has been successfully
+built in Ubuntu 17.04; Ubuntu 16.10 will not work because MeshLab needs Qt 5.7,
+which is not available there. It should be possible to build MeshLab as a snap
+in older Ubuntu distributions by using the [qt57
+part](https://wiki.ubuntu.com/snapcraft/parts), but no efforts have been taken
+in this direction since anyway the generated snap package will work on older
+distributions too.
+
+How to test the snap
+--------------------
+The generated snap can be installed by typing
+```
+snap install --dangerous ./meshlab*.snap
+```
+The `--dangerous` flag is needed because the snap has not been verified by the
+store.
+
+How to upload the snap to the store
+-----------------------------------
+A thorough guide can be found at the [snapcraft.io
+site](https://snapcraft.io/docs/build-snaps/publish).
