+# eslint-plugin-import/memo-parser
+
+
+## NOTE!
+
+This used to improve performance, but as of ESLint 5 and v2 of this plugin, it seems to just consume a bunch of memory and slightly increase lint times.
+
+**Not recommended for use at this time!**
+
+
+This parser is just a memoizing wrapper around some actual parser.
+
+To configure, just add your _actual_ parser to the `parserOptions`, like so:
+
+```yaml
+parser: eslint-plugin-import/memo-parser
+# parser: babel-eslint
+
+parserOptions:
+  parser: babel-eslint
+  sourceType: module
+  ecmaVersion: 6
+```
