+## About
 
-Firefly II is a tool to help you manage your finances. Please read the full description [in the wiki](https://github.com/JC5/firefly-iii/wiki/full-description).
+"Firefly III" is a financial manager. It can help you keep track of expenses, income, budgets and everything in between. It even supports credit cards, shared 
+household accounts and savings accounts! It's pretty fancy. You should use it to save and organise money.
 
-Firefly Mark III is a new version of Firefly built upon best practices and lessons learned
-from building [Firefly](https://github.com/JC5/Firefly). It's Mark III since the original Firefly never made it outside of my
-laptop and [Firefly II](https://github.com/JC5/Firefly) is live.
+Personal financial management is pretty difficult, and everybody has their own approach to it. Some people make budgets, other people limit their cashflow by throwing away their credit cards, others try to increase their current cashflow. There are tons of ways to save and earn money.
 
-## Current features
+Firefly works on the principle that if you know where you're money is going, you can stop it from going there.
 
-- [A double-entry bookkeeping system](http://en.wikipedia.org/wiki/Double-entry_bookkeeping_system);
-- You can store, edit and remove withdrawals, deposits and transfers. This allows you full financial management;
-- It's possible to create, change and manage money using _budgets_;
-- Organize transactions using categories;
-- Save towards a goal using piggy banks;
-- Predict and anticipate large expenses using "repeated expenses" (ie. yearly taxes);
-- Predict and anticipate bills using "recurring transactions" (rent for example);
-- View basic income / expense reports.
-- Lots of help text in case you don't get it;
+#### Some advantages of using Firefly
 
-Everything is organised:
+- Firefly can import any CSV file, so migrating from other systems is easy.
+- Firefly runs on your own server, so you are fully in control of your data. Remember, there is no such thing as "the cloud", it’s just somebody else’s computer!
+- Firefly has lots of features without becoming fancy or bloated.
+- If you feel you're missing something you can just ask me and I'll add it!
 
-- Clear views that should show you how you're doing;
-- Easy navigation through your records;
-- Browse back and forth to see previous months or even years;
-- Lots of charts because we all love them.
-
-## Changes
-
-Firefly III will feature, but does not feature yet:
-
-- Financial reporting showing you how well you are doing;
-- More control over other resources outside of personal finance
-  - Accounts shared with a partner (household accounts)
-  - Debts
-  - Credit cards
-- More test-coverage;
-- Firefly will be able to split transactions; a single purchase can be split in multiple entries, for more fine-grained control.
-- Firefly will be able to join transactions.
-- Any other features I might not have thought of.
-
-Some stuff has been removed:
-
-- The nesting of budgets, categories and beneficiaries is removed because it was pretty pointless.
-- Firefly will not encrypt the content of the (MySQL) tables. Old versions of Firefly had this capability but it sucks when searching, sorting and organizing entries.

-
-## Current state
-I have the basics up and running. Test coverage is currently coming, slowly.
-
-Although I have not checked extensively, some forms and views have CSRF vulnerabilities. This is because not all
-views escape all characters by default. Will be fixed.
-
-Questions, ideas or other things to contribute? [Let me know](https://github.com/JC5/firefly-iii/issues/new)!
+Firefly is pretty awesome. [You can read more about Firefly III, and its features, on the Github Pages](https://jc5.github.io/firefly-iii/).
