Fixed an off-by-one error and config loading for reader name

Reading card 3 and above resulted in an off by one error that always threw a "this line isn't X bytes long" error.

Readername now always gets properly loaded from config :
I've added comments in the config file to make it obvious what each line does but that fucked up the reader name config. i'm now discarding the comment after loading the line.

Updated readme.md

+# AimeIO CardReader
 
-PC/SC-based Aime card reader for `segatools`. `aimeio-pcsc` allows you to use PC/SC compliant smart card readers as your Aime card reader in `segatools`. `aimeio-pcsc` only properly supports the old Mifare Classic 1K-based Aime cards.
+This allows you to a smartcard reader (specifically the acr122u) with segatools
 
-If you scan a newer AIC-based Aime, its FeliCa IDm will be provided to the game. The game will not see the correct "access code," but the IDm should be unique to each card so that particular card can still track your plays. 
+**This has only been confirmed working with Chunithm Sun and Sun + so far. Luminous doesn't seem to work yet !**
 
-Tested on SONY's PaSoRi RC-S300. Other readers should, in theory, also work.
+# Acknowledgments
 
-### Usage
+This is a plugin destined to be used with [Dniel97](https://gitea.tendokyu.moe/Dniel97)'s [segatools fork](https://gitea.tendokyu.moe/Dniel97/segatools) (but should work on others too).
 
-To test if your card reader is supported, run `aimereader.exe` and try read your Aime card.
+SmartCard implementation taken from [spicetools](https://github.com/spicetools/spicetools)
+
+Initial project made by [nat](https://gitea.tendokyu.moe/nat/aimeio-pcsc)
+
+All the logic for reading cards from a file has been taken from [CrazyRedMachine](https://github.com/CrazyRedMachine)'s [RedBoard](https://github.com/CrazyRedMachine/RedBoard) aimeio.
+
+# Usage
+
+Make sure to install the ACR122U's [driver](https://www.acs.com.hk/en/driver/3/acr122u-usb-nfc-reader/) before using this.
 
 To use it with a game, copy `aimeio.dll` to your `segatools` folder and add the following to your `segatools.ini`:
 
 ```ini
 [aimeio]
-path=aimeio.dll
+path=aimeio.dll    ;Path to aimeio.dll
+scan=0x0D          ;Sets the key which will be used to insert a card in game. The default is 'Return'
+
+
+;Everything below this line is optional.
+
+readerOptional=1            ;Make reader optional, so that you can still use the keyboard
+readerName=ACS ACR122 0     ;Manually select which reader to use
+disableBuzzer=1             ;Disable the buzzer 
+;aimePath=""                ;Manually specify an aime.txt file
+;felicaPath=""              ;Manually specify a felica.txt file
+;debug=0                    ;Display function calls
 ```
 
-### Build
+## Scanning cards
 
-On Linux:
+If you scan a newer AIC-based Aime, its FeliCa IDm will be provided to the game. The game will not see the correct "access code," but the IDm should be unique to each card so that particular card can still track your plays.  
 
-```sh
-meson setup --cross cross-mingw-64.txt b64
-ninja -C b64
-```
+## Inserting cards
+
+By pressing the key you have set in segatools.ini and holding it for a few moments, you will insert a card set in either aime.txt or felica.txt
+
+You can have multiple cards in those files!  
+By holding a number from 0 to 9 on your keypad, and then holding enter, you can choose what card to insert.
+
+For example...
+
+```text
+aime.txt
+---
+
+1a7f3e925cb866d45a3b
+a5d04d668bc529e35aaa
+```
+
+By only pressing the insert key, you will insert card0, "1a7f3e925cb866d45a3b".  
+If you hold 1 on your numpad and press the insert key, card1, "a5d04d668bc529e35aaa" will be inserted !  
+
+This works for up to 10 cards.
+
+# Build
+
+To build this, you'll need two things :
+
+- [Meson 1.1.0](https://mesonbuild.com)
+- [Build Tools pour Visual Studio 2022](https://visualstudio.microsoft.com/fr/downloads/)
+
+Once you've edited your build64.bat file to point to your local installation of the VS2022 build tools, run build64.bat and the output will be located in `bin/aime.dll`.
