+
+###How to install
+
+####Bukkit/Spigot/PaperSpigot
+
+1. Download and install ProtocolLib
+2. Download and install FastLogin
+3. Set your server in offline mode by setting the value onlinemode in your server.properties to false
+
+####BungeeCord/Waterfall
+
+1. Activate BungeeCord in the Spigot configuration
+2. Restart your server
+3. Now there is proxy-whitelist file in the FastLogin folder
+Put your stats id from the BungeeCord config into this file
+4. Activate ipForward in your BungeeCord config
+5. Download and Install FastLogin on BungeeCord AND Spigot
+6. Check your database settings in the config of FastLogin on BungeeCord
+7. Set your proxy (BungeeCord) in offline mode by setting the value onlinemode in your config.yml to false
+8. (BungeeCord doesn't support SQLite per default, so you should change the configuration to MySQL or MariaDB)

+####How does minecraft logins work?
+######Online Mode
+1. Client -> Server: I want to login, here is my username
+2. Server -> Client: Okay. I'm in online mode so here is my public key for encryption and my serverid
+3. Client -> Mojang: I'm player "xyz". I want to join a server with that serverid
+4. Mojang -> Client: Session data checked. You can continue
+5. Client -> Server: I received a successful response from Mojang. Heres our shared secret key
+6. Server -> Mojang: Does the player "xyz" with this shared secret key has a valid account to join me?
+7. Mojang -> Server: Yes, the player has the following additionally properties (UUID, Skin)
+8. Client and Server: encrypt all following communication packet
+9. Server -> Client: Everything checked you can play now
+
+
+######Offline Mode
+In offline mode step 2-7 is skipped. So a login request is directly followed by 8.
+
+######More details
+http://wiki.vg/Protocol#Login
+
+####How does this plugin work?
+By using ProtocolLib, this plugin works as a proxy between the client and server. This plugin will fake that the server
+runs in online mode. It does everything an online mode server would do. This will be for example, generating keys or
+checking for valid sessions. Because everything is the same compared to an offline mode login after an encrypted
+connection, we will intercept only **login** packets of **premium** players.
+
+1. Player is connecting to the server.
+2. Plugin checks if the username we received activated the fast login method (i.e. using command)
+3. Run a check if the username is currently used by a paid account.
+(We don't know yet if the client connecting is premium)
+4. Request an Mojang Session Server authentication
+5. On response check if all data is correct
+6. Encrypt the connection
+7. On success intercept all related login packets and fake a new login packet as a normal offline login
+
+####Why does the plugin require offline mode?
+1. As you can see in the question "how does minecraft login works", offline mode is equivalent to online mode except of
+the encryption and session checks on login. So we can intercept and cancel the first packets for premium players and
+enable an encrypted connection. Then we send a new fake packet in order to pretend that this a new login request from
+a offline mode player. The server will handle the rest.
+2. Some plugins check if the server is in online mode. If so, they could process the real offline (cracked) accounts
+incorrectly. For example, a plugin tries to fetch the UUID from Mojang, but the name of the player is not associated to
+a paid account.
+3. Servers, who allow cracked players and just speed up logins for premium players, are **already** in offline mode.
+
+####Can cracked player join with premium usernames?
+Yes, indeed. Therefore the command for toggling the fast login method exists.
+
+####Why do players have to invoke a command?
+1. It's a secure way to make sure a person with a paid account cannot steal the account
+of a cracked player that has the same username. The player have to proof first that it's his own account.
+2. We only receive the username from the player on login. We could check if that username is associated
+to a paid account but if we request a online mode login from a cracked player (who uses a username from
+a paid account), the player will disconnect with the reason "bad login" or "Invalid session". There is no way to change
+that message on the server side (without client modifications), because it's a connection between the Client and the
+Sessionserver.
+3. If a premium player would skip registration too, a player of a cracked account could later still register the
+account and would claim and steal the account from the premium player. Because commands cannot be invoked unless the
+player has a account or is logged in, protects this method also premium players
+
+###What happens if a paid account joins with a used username?
+The player on the server have to activate the feature of this plugin by command. If a person buys the username
+of his own account, it's still secured. A normal offline mode login makes sure he's the owner of the server account
+and Mojang account. Then the command can be executed. So someone different cannot steal the account of cracked player
+by buying the username.
+
+####Does the plugin have BungeeCord support?
+Yes it has. See the how to install above.
+
+####Could premium players have a premium UUID and Skin?
+Since 0.7 both features are implemented. You can check the config.yml in order to activate it.
+
+####Is this plugin compatible with Cauldron?
+It's not tested yet, but all needed methods also exists in Cauldron so it could work together.

+# FastLogin config
+# Project site: https://www.spigotmc.org/resources/fastlogin.14153
+# Source code: https://github.com/games647/FastLogin
+#
+# You can access the newest config here:
+# https://github.com/games647/FastLogin/blob/master/core/src/main/resources/config.yml
+
+# Request a premium login without forcing the player to type a command
+#
+# If you activate autoRegister, this plugin will check/do these points on login:
+# 1. An existing cracked account shouldn't exist
+# -> paid accounts cannot steal the existing account of cracked players
+# - (Already registered players could still use the /premium command to activate premium checks)
+# 2. Automatically registers an account with a strong random generated password
+# -> cracked player cannot register an account for the premium player and so cannot the steal the account
+#
+# Furthermore the premium player check have to be made based on the player name
+# This means if a cracked player connects to the server and we request a paid account login from this player
+# the player just disconnect and sees the message: 'bad login' or 'invalid session'
+# There is no way to change this message
+# For more information: https://github.com/games647/FastLogin#why-do-players-have-to-invoke-a-command
+autoRegister: false
+
+# If this plugin detected that a player has a premium, it can also set the associated
+# uuid from that account. So if the players changes their usernames, they will still have
+# the same playerdata (inventory, permissions, ...)
+#
+# Warning: This also means that the UUID will be different if the player is connecting
+# through a offline mode connection. This **could** cause plugin compatibility issues.
+#
+# This is a example and doesn't apply for every plugin.
+# Example: If you want to ban players who aren't online at the moment, the ban plugin will look
+# after a offline uuid associated to the player, because the server is in offline mode. Then the premium
+# players could still join the server, because they have different UUID.
+#
+# Moreover you may want to convert the offline UUID to a premium UUID. This will ensure that the player
+# will have the same inventory, permissions, ... if they switched to premium authentification from offline/cracked
+# authentification.
+#
+# This feature requires Cauldron, Spigot or a fork of Spigot (PaperSpigot, TacoSpigot)
+premiumUuid: false
+
+# This will make an additional check (only for player names which are not in the database) against the mojang servers
+# in order to get the premium UUID. If that premium UUID is in the database, we can assume on sucessful login that the
+# player changed it's  username and we just update the name in the database.
+# Examples:
+# #### Case 1
+# nameChangeCheck = false ----- autoRegister = false
+#
+# Player logins as cracked until the player invoked the command /premium. Then we could override the existing database
+# record.
+#
+# #### Case 2
+#
+# nameChangeCheck = true ----- autoRegister = false
+#
+# Connect the Mojang API and check what UUID the player has (UUID exists => Paid Minecraft account). If that UUID is in
+# the database it's an **existing player** and FastLogin can **assume** the player is premium and changed the username.
+# If it's not in the database, it's a new player and **could be a cracked player**. So we just use a offline mode
+# authentication for this player.
+#
+# **Limitation**: Cracked players who uses the new username of a paid account cannot join the server if the database
+# contains the old name. (Example: The owner of the paid account no longer plays on the server, but changed the username
+# in the meanwhile).
+#
+# #### Case 3
+#
+# nameChangeCheck = false ----- autoRegister = true
+#
+# We will always request a premium authentication if the username is unknown to us, but is in use by a paid minecraft
+# account. This means it's kind of a more aggressive check like nameChangeCheck = true and autoRegister = false, because
+# it request a premium authentication which are completely new to us, that even the premium UUID is not in our database.
+#
+# **Limitation**: see below
+#
+# #### Case 4
+#
+# nameChangeCheck = true ----- autoRegister = true
+#
+# Based on autoRegister it checks if the player name is premium and login using a premium authentication. After that
+# fastlogin receives the premium UUID and can update the database record.
+#
+# **Limitation from autoRegister**: New offline players who uses the username of an existing minecraft cannot join the
+# server.
+nameChangeCheck: false
+
+# If your players have a premium account and a skin associated to their account, this plugin
+# can download the data and set it to the online player.
+#
+# Keep in mind that this will only works if the player:
+# * is the owner of the premium account
+# * the serverconnection is established through a premium connection (paid account authentification)
+# * has a skin
+#
+# This means this plugin doesn't need to create a new connection to the Mojang servers, because
+# the skin data is included in the Auth-Verification-Response sent by Mojang. If you want to use for other
+# players like cracked player, you have to use other plugins.
+#
+# If you want to use skins for your cracked player, you need an additional plugin like
+# ChangeSkin, SkinRestoer, ...
+forwardSkin: true
+
+# Displays a warning message that this message SHOULD only be invoked by
+# users who actually are the owner of this account. So not by cracked players
+#
+# If they still want to invoke the command, they have to invoke /premium again
+premium-warning: true
+
+# If you have autoRegister or nameChangeCheck enabled, you could be rate-limited by Mojang.
+# The requests of the both options will be only made by FastLogin if the username is unknown to the server
+# You are allowed to make 600 requests per 10-minutes (60 per minute)
+# If you own a big server this value could be too low
+# Once the limit is reached, new players are always logged in as cracked until the rate-limit is expired.
+# (to the next ten minutes)
+#
+# The limit is IP-wide. If you have multiple IPv4-Addreses you specify them here. FastLogin will then use it in rotating
+# order --> 5 different IP-addreses 5 * 600 per 10 minutes
+# If this list is empty only the default one will be used
+#
+# Lists are created like this:
+#ip-addresses:
+#    - 192-168-0-2
+ip-addresses: []
+
+# How many requests should be established until the plugin uses the third-party API https://mcapi.ca/
+# Once this number is reached in a range of ten minutes it will start connecting to https://mcapi.ca/ for the next ten minutes
+# This option exists in order to workaround the rate-limiting. Name -> UUID are fetched in the same way like heads
