+# MultiROM's Indiegogo campaign
+
+http://www.indiegogo.com/projects/multirom-for-nexus-7-2013/
+
+A crowdfunding campaign to get test devices took place from July 28th
+to August 27th 2013. Thanks all contributors, the campaign was successful,
+raising a total of $562. This enabled a purchase of _flo_ and resulted in
+MultiROM being ported to said device and the code became much more portable.
+
+These are the contributors who pledged $20 or more and got perk _The Code_:
+* jbaumert
+* viper08
+* marius15
+* x.nicow.x
+* Ben Hagen
+
+More contributors are named in the XDA thread or during build of
+`multirom_zip` target, but thanks goes to all who contributed, either
+by pledging money or by promoting the campaign. Thank you all.
