@ -768,6 +768,9 @@ Here are a few things to note when evaluating and using Bolt:
  can be reused by a new page or can be unmapped from virtual memory and you'll
  see an `unexpected fault address` panic when accessing it.

+* Bolt uses an exclusive write lock on the database file so it cannot be
+  shared by multiple processes.
+
 * Be careful when using `Bucket.FillPercent`. Setting a high fill percent for
  buckets that have random inserts will cause your database to have very poor
  page utilization.
