-## Roadmap
+MongoGento requires you to install :
 
-Not yet done
+ - MongoDB server >= 2.4 : http://docs.mongodb.org/manual/installation/
+ - MongoDB PHP driver on front : you can install it through PECL package http://pecl.php.net/package/mongo
 
+For development environment a single MongoDB instance deployment is sufficient. If you plan a production environment with a more complicated architecture (ReplicaSet or Sharding), you will add to test it strongly on this architecture before it will go live and at least testing environment should reproduce this architecture.
+
+

+# FAQ
+
+**Is it ready for production ?**
+
+> Previous versions of MongoGento are already into production on some websites. Some with millions of products.
+
+**Is there Magento modules that are reported as non-working with MongoGento ?**
+
+> Yes there is some broken features (the list is not exhaustive) :
+>
+ - Product catalog rules does not handle some attributes (confirmed
+compare does not see MongoDB attributes)
+>
+The following features have not been tested with MongoGento and should be considered as broken :
+>
+- Sitemap
+- Rule based product relations
+- Product tags and comments
+- Feel free to submit your report about untested features (OK / KO) and patches for broken features
+
+**What is the Roadmap ?**
+
+> We have several ideas we will evaluate into the roadmap :
+>
+- Integrate quotes / carts management
+- Integrate customer management
+- Restore most used broken features
+>
+Any idea is welcome.
