 ### `require_explicit_primary_key`
 
-Enforce that all tables must have a primary key.  If the primary key is `rowid`, it must be declared explicitly.
+Enforce that all tables must have an explicitly declared primary key.
 
 **Explanation**: 
 
-- All tables need to have a primary key, and it should usually be `rowid`.  Declaring it explicitly improves the readability of the schema.
+- All tables need to have a primary key for storage reasons, so if you don't declare one, SQLite will auto-generate a hidden "rowid" column.  Making it explicit (rowid or otherwise) improves schema readability.
+
+See more about the special behavior of `rowid` in SQLite's documentation: <https://sqlite.org/lang_createtable.html#rowid>
+
+### `require_explicit_rowid`
+
+Enforce that any table that's not declared `without rowid` has an explicit `rowid integer primary key` column.
+
+**Explanation**:
+
+- In SQLite, all tables implicitly have a `rowid` column unless they are declared `without rowid`.  Making it explicit improves schema readability.
+
+See more about the `without rowid` modifier in SQLite's documentation: <https://sqlite.org/withoutrowid.html>
+
+### `forbid_rowid_on_without_rowid_table`
+
+Enforce that `without rowid` tables don't have a rowid column.
+
+**Explanation**:
+
+- This is pretty self explanatory.  You can technically give a `without rowid` table a rowid column.  But don't.
