+Completion
 ======================================================================
+Omni completion is implemented for account names and tags.
+
+Accounts
+----------------------------------------------------------------------
+Account names are matched by the start of every sub-level.
+When you insert an account name like this:
+  Asse<C-X><C-O>
+You will get a list of top-level accounts that start like this.
+
+Go ahead and try something like:
+  As:Ban:Che<C-X><C-O>
+When you have an account like this, 'Assets:Bank:Checking' should show up.
+
+When you want to complete on a virtual transaction,
+it's currently best to keep the cursor in front of the closing bracket.
+Of course you can insert the closing bracket after calling the completion, too.
+
+Tags
+----------------------------------------------------------------------
+The support for completing tags is pretty basic right now
+but it's useful to keep the spelling of your tags consistent.
+You can call the completion after the ';' to get a list of all tags.
+When you have a list of tags (:like: :this:) you can call
+the completion too and everything up to the last ':' (excluding whitespace)
+will be considered the beginning of the tag to search for.
