+You can:

+- disable the Grammalecte button (spinning pearl),

+- launch the Grammalecte panel with custom button (or when you think it’s necessary),
+
+- get the modified text via events (instead of having the node content directly modified),

+- get raw results (list of errors) of grammar checking and spell checking,

+- get spelling suggestions for a wrong word.

+### How it works
+
+Usually, webpage scripts can’t call methods or functions of browser extensions.
+
+The Grammalecte API is injected within your webpage, with methods launching events that Grammalecte is listening. When Grammalecte receives one of these events, it launches the requested tasks. Results may be sent via events on webpage nodes.

 Every call to the Grammalecte API will be done via an object called `oGrammalecteAPI`.
