-Firefly Mark III is a new version of Firefly built upon best practices and lessons learned
+[![Screenshot](https://i.nder.be/g63q05m0/400)](https://i.nder.be/g63q05m0) [![Screenshot](https://i.nder.be/c2g30ngg/400)](https://i.nder.be/c2g30ngg)
-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.
 
-## Current features
+"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.
 
-- [A double-entry bookkeeping system](http://en.wikipedia.org/wiki/Double-entry_bookkeeping_system).
+## Installation
-- 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).
 
-Everything is organised:
+To install Firefly III, you'll need a web server (preferrably on Linux) and access to the command line. Then, please read the [installation guide](https://jc5.github.io/firefly-iii/installation-guide/).
 
-- Clear views that should show you how you're doing;
+## More about Firefly III
-- Easy navigation through your records;
-- Browse back and forth to see previous months or even years;
-- Lots of help text in case you don't get it;
-- Lots of charts because we all love them.
 
-## Changes
+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.
 
-Firefly III will feature, but does not feature yet:
+Firefly works on the principle that if you know where you're money is going, you can stop it from going there.
 
-- Financial reporting showing you how well you are doing;
+#### Some advantages of using Firefly
-- More control over other resources outside of personal finance
-  - Accounts shared with a partner (household accounts)
-  - Debts
-  - Credit cards
-- More test-coverage (aka: actual 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.
-- Transfers and transactions are combined into one internal datatype which is more consistent with what you're actually doing: moving money from A to B. The fact that A or B or both are yours should not matter.
-- Any other features I might not have thought of.
 
-Some stuff has been removed:
+- 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!
 
-- The nesting of budgets, categories and beneficiaries is removed because it was pretty pointless.
+Firefly is pretty awesome. [You can read more about Firefly III, and its features, on the Github Pages](https://jc5.github.io/firefly-iii/).
-- 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
+If you want to contact me, please open an issue or [email me](mailto:thegrumpydictator@gmail.com).
-I have the basics up and running. Test coverage is currently non-existent.
-
-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.
-
-The current layout / look & feel is a pretty basic Bootstrap3 template. I am currently working on a more consistent,
-expanded layout which will feature shiny AJAX things and data tables and all the Web 3.0 goodies you've come to expect
-from social media sites.
-
-Questions, ideas or other things to contribute? [Let me know](https://github.com/JC5/firefly-iii/issues/new)!
