 ## Setup
-Requires a MySQL/Mongo/PostgreSQL database, a Redis (v5.0+) server and a network of Spigot (1.17.1+) or Fabric (1.20.1) Minecraft servers, running Java 17+.
+Requires a [MySQL/MariaDB/Mongo/PostgreSQL database](https://william278.net/docs/husksync/database), a [Redis (v5.0+) server]((https://william278.net/docs/husksync/redis)) and a network of [compatible Spigot or Fabric Minecraft servers](https://william278.net/docs/husksync/compatibility).
 
 1. Place the plugin jar file in the `/plugins` or `/mods` directory of each Spigot/Fabric server. You do not need to install HuskSync as a proxy plugin.
 2. Start, then stop every server to let HuskSync generate the config file.

+## Incompatible plugins / mods

+
+* Restart plugins / mods are not supported. These will cause [player data to not save correctly when your server restarts](troubleshooting#issues-with-player-data-going-out-of-sync-during-a-server-restart) due to the way these plugins utilise bash scripts. It's important to understand that restart plugins don't actually restart yur server, they just trigger some (often unstable) process-killing scripting logic to occur!
+* Combat logging plugins / mods are not supported. Some have built-in support for HuskSync and should work as expected, but for others you may wish to modify the [[Event Priorities]]

+### Credentials
+You will need to specify the credentials (hostname, port, username, password and the database). These credentials are used to connect to your database server.
+
+If your database server account doesn't have a password (not recommended), leave the password field blank (`password: ''`') and the plugin will attempt to connect without a password.
+
+### Connection Pool properties
+If you're using MySQL, MariaDB, or PostgreSQL as your database type, you can modify the HikariCP connection pool properties if you know what you're doing.
+
+Please note that modifying these values can cause issues if you don't know what you're doing. The default values should be fine for most users. 
+
+## MongoDB Setup
+If you're using a MongoDB database, in addition to setting the database type to `MONGO`, you'll need to perform slightly different configuration steps.
+
+- Under `credentials` in the `database` section, enter the credentials of your MongoDB Database. You shouldn't touch the `connection_pool` properties.
+- Under `parameters` in the `mongo_settings` section, ensure the specified `&authSource=` matches the database you are using (default is `HuskSync`).
+
+### MongoDB Atlas setup
+If you're using a MongoDB Atlas database, you'll also need to set the Atlas settings and adjust the connection parameters string.
+
+- Set `using_atlas` in the `mongo_settings` section to `true`.
+- Remove `&authSource=HuskSync` from `parameters` in the `mongo_settings`.
+
+Note that the `port` setting in `credentials` is ignored when using Atlas.

 The performance improvements offered by HuskSync's synchronization method will depend on your network environment and the economies of scale that come with your player count. In terms of featureset, HuskSync does feature greater rollback and snapshot backup/management features if this is something you are looking for.

+Redis is a piece of server used for data caching and cross-server messaging. A Redis server running Redis v5.0+ is **required** in addition to a compatible [[Database]] to use HuskSync. There are a number of ways of [installing or getting a Redis server](#getting-a-redis-server).
+
+For the best results, we recommend a Redis server with 1GB of RAM, hosted locally (on the same machine as all your other servers). If your setup has multiple machines, install Redis on the machine with your Velocity/BungeeCord/Waterfall proxy server and ensure lockstep syncing mode is in use.
+
+## What is Redis?
+[Redis](http://redis.io/) (**RE**mote **DI**ctionary **S**erver) is an open-source, in-memory data store server that can be used as a cache, message broker, streaming engine, or database.
+
+HuskSync requires Redis and uses it for caching player data when they change server, and for pub/sub messaging to facilitate cross-server admin actions (such as the [`/invsee` command](Commands) to update a player's data on other servers). Check the [[FAQs]] for more details.
+
+## Configuring
+To configure Redis, navigate to your [`config.yml`](Config-File) file and modify the properties under `redis`.
+
+<details>
+<summary>Database options (config.yml)</summary>

+
+If your Redis default user doesn't have a password, leave the password field blank (`password: ''`') and the plugin will attempt to connect without a password.
+
+### Default user password
+Depending on the version of Redis you've installed, Redis may or may not set a random default user password. Please check this in your Redis server config. You can clear the password of the default user with the below command in `redis-cli`.
+
+```bash
+requirepass thepassword
+user default on nopass ~* &* +@all
+```
+
+### Using Redis Sentinel
+If you're using [Redis Sentinel](https://redis.io/docs/latest/operate/oss_and_stack/management/sentinel/), set this up by filling out the properties under the `sentinel` subsection.
+

+## Getting a Redis Server
+HuskSync requires a Redis server. Instructions for getting Redis on different servers are detailed below. HuskSync is tested for the official Redis package, but should also work with Redis forks or other compatible software.
+
+For the best results, we recommend a Redis server with 1GB of RAM, hosted locally (on the same machine as all your other servers). If your setup has multiple machines, install Redis on the machine with your Velocity/BungeeCord/Waterfall proxy server and ensure lockstep syncing mode is in use.
+
+### If you're using a Minecraft server hosting provider
+Please contact your host's customer support and request Redis. You can direct them to this page if you wish. Looking for a Minecraft Server host that supports Redis? We maintain a list of [server hosts which offer Redis](https://william278.net/docs/website/redis-hosts).
+
+If your host doesn't offer Redis, you should consider whether HuskSync is the right plugin for you. If you still want to use HuskSync, you could choose to rent a cheap Redis server externally from a provider such as DigitalOcean, though note we don't recommend this as it increases the latency between your game servers and cache, which will impact syncing performance.
+
+### Redis on Linux or macOS
+You can [install Redis](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-linux/) on your distribution of Linux. Redis is widely available on most package manager repositories.
+
+You can also [install Redis](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-mac-os/) on your macOS server.
+
+### Redis on Windows
+Redis isn't officially supported on Windows, but there's a number of [unofficial ports](https://github.com/tporadowski/redis/releases) you can install which work great and run Redis as a Windows service.
+
+You can also [install Redis via WSL](https://redis.io/docs/latest/operate/oss_and_stack/install/install-redis/install-redis-on-windows/) if you prefer.
+
+### Pterodactyl / Pelican panel hosts
+If you're self-hosting your server on a Pterodactyl or Pelican panel, you will already have Redis installed and can use this server for HuskSync, too.
+
+If you are hosting your Redis server on the same node as your servers, you need to use `172.18.0.1` as your host (or equivalent if you changed your network settings), and bind it in the Redis config `nano /etc/redis/redis.conf`.
+
+You will also need to uncomment the `requirepass` directive and set a password to allow outside connections, or disable `protected-mode`. Once a password is set and Redis is restarted `systemctl restart redis`, you will also need to update the password in your pterodactyl `.env` (`nano /var/www/pterodactyl/.env`) and refresh the cache `cd /var/www/pterodactyl && php artisan config:clear`.
+
+You may also need to allow connections from your firewall depending on your Linux distribution.

 ### Exceptions when compressing data via Snappy (lightweight Linux distros)
 Some lightweight Linux distros such as Alpine Linux (used on Pterodactyl) might not have the dependencies needed for the [Snappy](https://github.com/xerial/snappy-java) compressor. It's possible to disable data compression by changing `compress_data` to false in your config. Note that after changing this setting you will need to reset your database. Alternatively, find the right libraries for your distro!
 
-### Redis connection problems on Pterodactyl
-If you are hosting your Redis server on the same node as your servers, you need to use 172.18.0.1 (or equivelant if you changed your network settings) as your host. You may also need to [allow connections from your firewall](https://pterodactyl.io/community/games/minecraft.html#firewalls) depending on your distribution.

+If you have more than one [[Database]] server connected to your panel, you may need to set `useSSL=true` in the parameters.
+
+### Issues with player data going out of sync during a server restart
+This can happen due to the way in which your server restarts. If your server uses either:
+
+* `/restart` (this is a weird Spigot/Fabric command that uses legacy bash scripting)
+* ANY restart plugin, e.g. UltimateAutoRestart (these basically execute an API-called restart using the same legacy bash logic as per above)
+
+These are **not compatible** with HuskSync in most cases due to the way in which this causes restart servers causing shutdown logic to process in strange and unpredictable orders, usually before HuskSync has had a chance to scan and perform its shutdown logic. To safely restart your server, please use:
+
+* A Pterodactyl task to perform a Restart. This executes the Power Action program stopcode (and then execute the startup command when the container has terminated)
+* A cronjob to send a stop command / Power Action program stopcode, listen for the service to fully terminate, and then execute your startup command
+* For manual restarts, executing `/stop` and starting your server up with the startup command is totally fine.
+
+It's not a great idea to use a plugin to handle restarts. Plugins are only able to operate when your server is turned on and must rely on scripts which don't safely shutdown servers when restarting.
