-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).
+## About
 
-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.
+"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.
+ 
+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 works on the principle that if you know where you're money is going, you can stop it from going there.
+
+To get to know Firefly, and to see if it fits you, check out these resources:
+
+- The screenshots below on this very page.
+- The featurelist below, also on this very page.
+- The [full description](https://github.com/JC5/firefly-iii/wiki/full-description), which will tell you how Firefly works,
+and the philosophy behind it.
+
+#### A quick technical overview
+
+Firefly is a system you'll have install yourself on webhosting of your choosing. It needs PHP and MySQL. The current version of Firefly III requires PHP 5.6.4 or
+higher. Soon, this will be PHP 7.0.0 or higher.
+
+
+#### About the name (should you care)
+
+It's III, or 3, because [version 2](https://github.com/JC5/Firefly) and version 1 (not online) preceded it. It has been growing steadily ever since.
 
 ## Current features
 
-- [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_;
+- [A double-entry bookkeeping system](https://en.wikipedia.org/wiki/Double-entry_bookkeeping_system);
+- You can store, edit and remove [withdrawals, deposits and transfers](https://en.wikipedia.org/wiki/Financial_transaction). This allows you full financial management;
+- You can manage different types of accounts;
+  - [Asset](https://en.wikipedia.org/wiki/Asset) accounts
+  - Shared [asset accounts](https://en.wikipedia.org/wiki/Asset) ([household accounts](https://en.wikipedia.org/wiki/Household))
+  - Saving accounts
+  - Credit cards
+- It's possible to create, change and manage money using _[budgets](https://en.wikipedia.org/wiki/Envelope_system)_;
 - 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).
+- Save towards a goal using [piggy banks](https://en.wikipedia.org/wiki/Piggy_bank);
+- Predict and anticipate [bills](https://en.wikipedia.org/wiki/Invoice);
+- View income / expense [reports](https://en.wikipedia.org/wiki/Financial_statement);
+- Organize expenses using tags;
+- Lots of help text in case you don't get it.
 
 Everything is organised:
 
 - 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;
-- Lots of help text in case you don't get it;
-- 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:
-
-- 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.
+- Lots of charts because we all love them;
+- Financial reporting showing you how well you are doing.

+## Running and installing
+
+If you're still interested please read [the installation guide](https://github.com/JC5/firefly-iii/wiki/Installation), 
+[the upgrade guide](https://github.com/JC5/firefly-iii/wiki/Upgrade-instructions) (if applicable) 
+and the **[first use guide](https://github.com/JC5/firefly-iii/wiki/First-use)**.
+ 
+If you want to try out Firefly III, you can do so on [this dedicated website](https://geld.nder.be/). 
+This site always runs the latest version of Firefly III. If you want to use it, please read the [privacy considerations](https://github.com/JC5/firefly-iii/wiki/Privacy-on-demo-site) for this demo-site. Accounts on the demo sites will stop working after one month. It's a trial.
+
+## Security
+
+You should always run Firefly III on a site with TLS enabled (https://). Please note that although some parts of the
+database are encrypted (transaction descriptions, names, etc.) some parts are _not_ (amounts, dates, etc). If you need
+more security, you must enable transparent database encryption or a comparable technology. Please remember that this
+is open source software under active development, and it is in no way guaranteed to be safe or secure.
+
+## Translations
+
+Firefly III is currently available in Dutch and English. Support for other languages is being worked on. I could use
+your help. Checkout [Crowdin](https://crowdin.com/project/firefly-iii) for more information.
+
+## Credits
+
+Firefly III uses the following libraries and tools:
+
+* The AdminLTE template by [Almsaseed Studio](https://almsaeedstudio.com/)
+* The [Google charts](https://developers.google.com/chart/) library.
+* [Chart.js](http://www.chartjs.org/)
+* [Bootstrap](http://getbootstrap.com/)
+* [Laravel](http://laravel.com/)
+* [Twig](http://twig.sensiolabs.org/)
+* For development, some of the excellent tools made by [Barry van den Heuvel](https://github.com/barryvdh)
+* [Bootstrap sortable](https://github.com/drvic10k/bootstrap-sortable) by [Matúš Brliť](https://github.com/drvic10k).
+* [Date range picker](https://github.com/dangrossman/bootstrap-daterangepicker/) by [Dan Grossman](https://github.com/dangrossman)
+* The [real favicon generator](http://realfavicongenerator.net/)

 ## Current state
-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.
+Firefly III is pretty much all grown up. Full test coverage (nerd alert!) is coming. Translations are a work in progress.
 
-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.
