+### "Corrupted zip or bug : unexpected signature"
+
+If you are sure that the zip file is correct, that error often comes from a
+corrupted content. An ajax request, if not prepared correctly, will try to
+decode the binary content as a text and corrupt it. See
+[this page]({{site.baseurl}}/documentation/howto/read_zip.html).
+
+### My browser crashes / becomes unresponsive / never finish the execution
+
+That happens if you try to handle to much data. If possible, try again with a
+small (some KB) zip file to see if your code is correct. See
+[this page]({{site.baseurl}}/documentation/limitations.html) for more
+informations.
