-### How can Spout handle such large data sets and still use less than 3MB of memory?
+### How can {{ site.spout_html }} handle such large data sets and still use less than 3MB of memory?
 
-When writing data, Spout is streaming the data to files, one or few lines at a time. That means that it only keeps in memory the few rows that it needs to write. Once written, the memory is freed.

 Same goes with reading. Only one row at a time is stored in memory. A special technique is used to handle shared strings in XLSX, storing them - if needed - into several small temporary files that allows fast access.

-### Does Spout support charts or formulas?
+### Does {{ site.spout_html }} support charts or formulas?
 
 No. This is a compromise to keep memory usage low. Charts and formulas requires data to be kept in memory in order to be used.
 So the larger the file would be, the more memory would be consumed, preventing your code to scale well.
