 **The \`spell\_dbc\` table**
 
-This table contains data regarding serverside spells which are not to be found in Client DBC files.
+This table contains data regarding serverside spells which are not to be found in Client DBC files as well as **overrides** of the DBC that are meant to improve or fix any spell.
+
+If you want to add more overrides, please first extract the needed SQL spell row using the [node-dbc-reader](https://github.com/wowgaming/node-dbc-reader) then you can use a `UPDATE` query to change the fields that you need to override.
+
+Fixes for this table should always contain:
+
+1) the `INSERT IGNORE` query adding the original spell from the DBC
+2) the `UPDATE` query containing the desired overrides
