The Intermuse interface comes with a pre-installed Mirador viewer with Annotations Plugin.
In time, this web extension will come pre-bundled with the necessary JS/CSS already produced

For now:

One tine only:

    ./UNTAR-MIRADOR-SRC.sh    
    ./NPM-INSTALL-MIRADOR.sh

Followed by:

    ./NPM-WEBPACK-MIRADOR.sh
    ./INSTALL-MIRADOR.sh
    
which needs to be run each time you make changes to the
mirador-integration-annotations source code.
