+HuskSync is primarily developed against the latest release. Old Minecraft versions are allocated a support channel based on popularity, mod support, etc:
+
+* Long Term Support (LTS) &ndash; Supported for up to 12-18 months
+* Non-Long Term Support (Non-LTS) &ndash; Supported for 3-6 months
+
+Verify your purchase on Discord and [Download HuskSync](https://william278.net/project/husksync#download) for your server.
+
+## Setup
+Requires a MySQL/Mongo/PostgreSQL database, a Redis (v5.0+) server and a network of Spigot or Fabric Minecraft servers (see [Compatibility](#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.
-3. Navigate to the HuskSync config file on each server (~/plugins/HuskSync/config.yml) and fill in both your database and Redis server credentials.

+HuskSync is primarily developed against the latest release. Old Minecraft versions are allocated a support channel based on popularity, mod support, etc:
+
+* Long Term Support (LTS) – Supported for up to 12-18 months
+* Non-Long Term Support (Non-LTS) – Supported for 3-6 months
+
+## Incompatible versions
+This plugin does not support the following software-Minecraft version combinations. The plugin will fail to load if you attempt to run it with these versions. Apologies for the inconvenience.

+### 3.1 Identifier dependencies
+* HuskSync lets you specify a set of `Dependency` objects when creating an `Identifier`. These are used to deterministically apply data in a specific order.
+* Dependencies are references to other data type identifiers. HuskSync will apply data in dependency-order; that is, it will apply the data of the dependencies before applying the data of the dependent.
+* This is useful when you have data that relies on other data to be applied first; for example, if you're writing an add-on for additional modded inventory data and you need to apply the base inventory data first.
+* You can specify whether a dependency is required or optional. HuskSync will not sync data of a type that has a required dependency that is missing (for instance, if it is disabled in the config, or - if provided by another plugin - has failed to register).
+* Use `Identifer#from(String, String, Set<Dependency>)` or `Identifier#from(Key, Set<Dependency>)` to create an identifier with dependencies
+* Dependencies can be created with `Dependency.optional(Identifier)` or `Dependency.required(Identifier)` for optional or required dependencies respectively.
+
 ## 4. Setting and getting our Data to/from a User
 * Now that we've registered our `Data` and `Serializer` classes, we can set our data to a user, applying it to them.
 * To do this, we use the `OnlineUser#setData(Identifier, Data)` method.
   * This method will apply the data to the user, and store the data to the plugin player custom data map, to allow the data to be retrieved later and be saved to snapshots.
 * Snapshots created on servers where the data type is registered will now contain our data and synchronise between instances!
