+## Notice
+I am now maintaining OpenInv over at [Jikoo/OpenInv](https://github.com/Jikoo/OpenInv) because I needed higher levels of access to add secrets to the repository for Github Actions. It feels ruder to send an email saying what amounts to "pls op" than to redirect people to my fork, though neither option is polite. Existing issues will remain open here until resolved (you can't transfer issues across organizations/users), but any new issues in this repo will be closed without resolution.
+
+## About
+OpenInv is a [Bukkit plugin](https://dev.bukkit.org/bukkit-plugins/openinv/) which allows users to open and edit anyone's inventory or ender chest - online or not!
+
+## Features
+- **OpenInv**: Open anyone's inventory, even if they're offline.
+  - Read-only mode! No edits allowed! Don't grant the permission `OpenInv.editinv`
+  - Cross-world support! Don't grant `OpenInv.crossworld`
+  - No self-opening! Don't grant `OpenInv.openself`
+  - Drop items as the player! Place items in the unused slots to the right of the armor to drop them
+- **OpenEnder**: Open anyone's ender chest, even if they're offline.
+  - Read-only mode! No edits allowed! Don't grant `OpenInv.editender`
+  - Cross-world support! Don't grant `OpenInv.crossworld`
+  - No opening others! Don't grant `OpenInv.openenderall`
+- **SilentContainer**: Open containers without displaying an animation or making sound.
+- **AnyContainer**: Open containers, even if blocked by ocelots or blocks.

+## For Developers
+To compile, the relevant Craftbukkit/Spigot jars must be installed in your local repository using the install plugin.
+Ex: `mvn install:install-file -Dpackaging=jar -Dfile=spigot-1.8-R0.1-SNAPSHOT.jar -DgroupId=org.spigotmc -DartifactId=spigot -Dversion=1.8-R0.1-SNAPSHOT`
+
+To compile for a single version, specify the NMS revision you are targeting: `mvn -pl <NMS module> -am clean install`
+
+To compile for a set of versions, you'll need to use a profile. The only provided profile is `all`. Select a profile using the `-P` argument: `mvn clean package -am -P all`
+
+For more information, check out the [official Maven guide](http://maven.apache.org/guides/introduction/introduction-to-profiles.html).
+
+The final file is `target/OpenInv.jar`

- * Check dev.bukkit.org to find updates for a given plugin, and download the updates if needed.
- * <p/>
- * <b>VERY, VERY IMPORTANT</b>: Because there are no standards for adding auto-update toggles in your plugin's config, this system provides NO CHECK WITH YOUR CONFIG to make sure the user has allowed
- * auto-updating. <br>
- * It is a <b>BUKKIT POLICY</b> that you include a boolean value in your config that prevents the auto-updater from running <b>AT ALL</b>. <br>
- * If you fail to include this option in your config, your plugin will be <b>REJECTED</b> when you attempt to submit it to dev.bukkit.org.
- * <p/>
- * An example of a good configuration option would be something similar to 'auto-update: true' - if this value is set to false you may NOT run the auto-updater. <br>
- * If you are unsure about these rules, please read the plugin submission guidelines: http://goo.gl/8iU5l
