+Description of Twitter bootstrap import into Moodle
+
+Twitter bootstrap
+-----------------
+
+Sass:
+This theme uses Bootstrap version 4.6.0
+The Bootstrap repository is available on:
+
+https://github.com/twitter/bootstrap.git
+
+To update to the latest release of twitter bootstrap:
+
+* download bootstrap to your home folder
+* remove folder theme/ilb/scss/bootstrap
+* copy the scss files from ~/bootstrap/scss to theme/ilb/scss/bootstrap
+* comment out left: 0; from .popover {} in scss/bootstrap/_popover.scss. In RTL mode this prevents popovers from showing and it is not required in LTR mode.
+* comment out this line in theme/ilb/scss/_print.scss
+    @page {
+       size: $print-page-size;
+    }
+  It breaks when compiled with phpscss.
+* update ./thirdpartylibs.xml
+
+Javascript:
+
+* remove folder theme/ilb/amd/src/bootstrap
+* copy the js files from ~/bootstrap/js/src to theme/ilb/amd/src/bootstrap (including the subfolder)
+* copy index.js from ~/bootstrap/js to theme/ilb/amd/src
+* edit theme/ilb/amd/src/index.js and update import path (src -> bootstrap)
+* Moodle core includes the popper.js library, make sure each of the new Bootstrap js files
+includes the 'core/popper' library instead of 'popper.js'. For version 4.6.0 these files were: tooltip.js and dropdown.js
+* update ./thirdpartylibs.xml to include all new Bootstrap js files
+* run "grunt ignorefiles" to prevent linting errors appearing from the new Bootstrap js files.
+* in folder theme/ilb run "grunt amd" to compile the bootstrap JS
+* in folder theme/ilb run "grunt css" to compile scss
