+## Ignored Features
+
+Emacsql doesn't cover all of SQLite's features, focusing on the most
+important syntax. Here are a list of things that aren't supported, and
+probably will never be.
+
+ * Collating. SQLite has three built-in collation functions: BINARY
+ (default), NOCASE, and RTRIM. Emacsql values never have right-hand
+ whitepsace, so RTRIM won't be of any use. NOCASE is broken
+ (ASCII-only) and there's little reason to use it.
+
+ * Databases attachments. I don't expect any program using Emacsql to
+ become so complex as to warrant multiple databases. Ignoring this
+ removes unneeded complexity.
+
+ * Date and time. These are incompatible with the printed values
+ stored by Emacsql and therefore have little use.

## Limitations
Emacsql is *not* intended to play well with other programs accessing
