+
+Usage
+=====
+
+Define a member product, and select 'Fixed amount' or 'Percentage of the price'
+for invoicing an extra charge in the first invoice that is created with this
+member product.
+
+By default, a line with the description *Membership initial fee*. If you want
+to change this text, you can set a different sale description in the product
+used for the fee.
+
+Known issues / Roadmap
+======================
+
+* Add initial fee information to membership analysis.
+* Add some criteria for adding initial fee:
+   * Add initial fee if last membership ended x weeks/months/years ago
+   * Add initial fee if last membership product_id is different
