+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

-# HuskSync API v2
-![](https://jitpack.io/v/WiIIiam278/HuskSync.svg)
-
 The HuskSync API provides methods for retrieving and updating user data, as well as a number of events for tracking when user data is synced and saved. 
 
-The API is distributed via [JitPack](https://jitpack.io/#net.william278/HuskSync). Please note that the HuskSync v1 API is not compatible.
+## Compatibility
-(Some) javadocs are also available to view on Jitpack [here](https://javadoc.jitpack.io/net/william278/HuskSync/latest/javadoc/).

+
+The HuskSync API shares version numbering with the plugin itself for consistency and convenience. Please note minor and patch plugin releases may make API additions and deprecations, but will not introduce breaking changes without notice.
+
+| API Version |  HuskSync Versions  | Supported |
+|:-----------:|:--------------------:|:---------:|

-HuskSync requires Redis to operate (for reasons demonstrated below). Redis is an in-memory database server used for caching data at scale and sending messages across a network. You have a Redis server in a similar fashion to the way you have a MySQL database server. If you're using a Minecraft hosting company, you'll want to contact their support and ask if they offer Redis. If you're looking for a host, I have a list of some popular hosts and whether or not they support Redis [available to read here.](https://william278.net/redis-hosts)

+No. MMOItems and SlimeFun are not compatible with HuskSync due to the way they inject data directly into item NBT rather than the Spigot API's plugin-agnostic PersistentDataContainer.

 HuskSync makes use of both MySQL and Redis for optimal data synchronisation.
 
 When a user changes servers, in addition to data being saved to MySQL, it is also cached via the Redis server with a temproary expiry key. When changing servers, the receiving server detects the key and sets the user data from Redis. When a player rejoins the network, the system fetches the last-saved data snapshot from the MySQL Database.
 
-This approach is able to dramatically improve both synchronisation performance and reliability. A few other techniques are used to optimize this process, such as comrpessing the serialized user data json using Snappy.

-I can't provide a fair answer to this question! What I can say is that your mileage may vary. The performance improvements offered by HuskSync's synchronisation method will depend on your network environment and the economies of scale that come with your player count.
+I can't provide a fair answer to this question! What I can say is that your mileage may vary. 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.
+
+With that said, servers running plugins or mods that make use of custom items (such as MMOItems, SlimeFun) are not supported by HuskSync and so MySQLPlayerDataBridge may be a better choice for you.
 
 A migrator from MPDB is built-in to HuskSync.

 ### PersistentDataContainer tags
-The player [PersistentDataContainer](https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/) is a part of the Spigot API that enables plugins to set custom data tags to players, entities & items and have them persist. HuskSync will synchronise this data cross-server. Plugins that use legacy or propietary forms of saving data, such as by modifying NBT directly, may not correctly synchronise.

 ### Custom enchantments
 Plugins that add custom enchantments by registering them to ItemStacks through setting them via the [EnchantmentStorageMeta](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/EnchantmentStorageMeta.html) will work, but note that the plugin _must_ be lower on the load order than HuskSync; in other words, HuskSync should be on the plugin's `loadbefore:`. This is because Spigot's item serialization API requires that the plugin that registered the enchantment be online to serialize it due to how it reads from the enchantment registry and so if the plugin does not load before (and thus does not shut down after) HuskSync, it won't be able to serialize the custom enchantments in the event of a server shutdown with players online.
