+# jupyterlab_spellchecker
+
+A spell checker extension for markdown cells in jupyterlab notebooks. 
+
+Highlights misspelled words.
+
+Based entirely on [this jupyter notebook extension](https://github.com/ipython-contrib/jupyter_contrib_nbextensions/tree/master/src/jupyter_contrib_nbextensions/nbextensions/spellchecker).
+
+Uses [Typo.js](https://github.com/cfinke/Typo.js) under the hood for spell checking. 
+
+Currently only uses the `en_US` dictionary loaded from the [jsdelivr.net cdn](https://www.jsdelivr.com/).
