-LuckPerms is an advanced permissions implementation aiming to be a fast, reliable and flexible alternative to existing permission plugins. The project's main goals are centered around high performance and a wide feature set, filling the gaps of functionality and building upon existing features found in other plugins.
+LuckPerms is a permissions plugin for Minecraft servers. It allows server admins to control what features players can use by creating groups and assigning permissions.

-LuckPerms also includes an extensive API for developers, and support for a variety of Minecraft server software & data storage options.
+The latest downloads, wiki & other useful links can be found on the project homepage at [luckperms.net](https://luckperms.net/).

-The main features of the project are detailed on this wiki page: [Why LuckPerms?](https://github.com/lucko/LuckPerms/wiki/Why-LuckPerms)
+It is:

-* [Spigot Plugin Release Page](https://www.spigotmc.org/resources/luckperms-an-advanced-permissions-system.28140/ "Spigot Plugin Page")
-* [Sponge Plugin Release Page](https://forums.spongepowered.org/t/luckperms-an-advanced-permissions-system/14274 "Sponge Plugin Page")
+* **fast** - written with performance and scalability in mind.
+* **reliable** - trusted by thousands of server admins, and the largest of server networks.
+* **easy to use** - setup permissions using commands, directly in config files, or using the web editor.
+* **flexible** - supports a variety of data storage options, and works on lots of different server types.
+* **extensive** - a plethora of customization options and settings which can be changed to suit your server.
+* **free** - available for download and usage at no cost, and permissively licensed so it can remain free forever.

-## Useful Links
-* **Downloads** - <https://ci.lucko.me/job/LuckPerms>

 ## Building
-LuckPerms uses Maven to handle dependencies.
+LuckPerms uses Gradle to handle dependencies & building.

 #### Requirements
-* Java 8 JDK
-* Maven 3.3.x (the older versions will not work.)
+* Java 17 JDK or newer
 * Git

-#### Then run
+#### Compiling from source
 ```sh
-git clone https://github.com/lucko/LuckPerms.git
+git clone https://github.com/LuckPerms/LuckPerms.git
 cd LuckPerms/
-mvn clean package
+./gradlew build
 ```

-You can find the output jars in the `target` directories.
+You can find the output jars in the `loader/build/libs` or `build/libs` directories.
+
+## Tests
+There are some automated tests which run during each build.
+
+* Unit tests are defined in [`common/src/test`](https://github.com/LuckPerms/LuckPerms/tree/master/common/src/test)
+* Integration tests are defined in [`standalone/src/test`](https://github.com/LuckPerms/LuckPerms/tree/master/standalone/src/test).

-/**
- * Represents a LuckPerms "node".
- *
- * <p>The {@link Node} class encapsulates more than just permission assignments.
- * Nodes are used to store data about inherited groups, as well as assigned
- * prefixes, suffixes and meta values.</p>
- *
- * <p>Combining these various states into one object (a "node") means that a
- * holder only has to have one type of data set (a set of nodes) in order to
- * take on various properties.</p>
- *
- * <p>It is recommended that users of the API make use of {@link Stream}s
- * to manipulate data and obtain the required information.</p>
- *
- * <p>This interface provides a number of methods to read the attributes of the
- * node, as well as methods to query and extract additional state and properties
- * from these settings.</p>
- *
- * <p>Nodes have the following attributes:</p>
- * <p></p>
- * <ul>
- *     <li>{@link #getPermission() permission} - the actual permission string</li>
- *     <li>{@link #getValuePrimitive() value} - the value of the node (false for negated)</li>
- *     <li>{@link #isOverride() override} - if the node is marked as having special priority over other nodes</li>
- *     <li>{@link #getServer() server} - the specific server where this node should apply</li>
- *     <li>{@link #getWorld() world} - the specific world where this node should apply</li>
- *     <li>{@link #getContexts() context} - the additional contexts required for this node to apply </li>
- *     <li>{@link #getExpiry() expiry} - the time when this node should expire</li>
- * </ul>
- *
- * <p>Nodes can also fall into the following sub categories.</p>
- * <p></p>
- * <ul>
- *     <li>normal - just a regular permission</li>
- *     <li>{@link #isGroupNode() group node} - a "group node" marks that the holder should inherit data from another group</li>
- *     <li>{@link #isPrefix() prefix} - represents an assigned prefix</li>
- *     <li>{@link #isSuffix() suffix} - represents an assigned suffix</li>
- *     <li>{@link #isMeta() meta} - represents an assigned meta option</li>
- * </ul>
- *
- * <p>The core node state must be immutable in all implementations.</p>

- * A set of contexts.
- *
- * <p>Context in the most basic sense simply means the circumstances where
- * something will apply.</p>
- *
- * <p>A single "context" consists of a key and a value, both strings. The key
- * represents the type of context, and the value represents the setting of the
- * context key.</p>
- *
- * <p>Contexts can be combined with each other to form so called
- * "context sets" - simply a collection of context pairs.</p>
- *
- * <p>Context keys are case-insensitive, and will be converted to
- * {@link String#toLowerCase() lowercase} by all implementations.
- * Values however are case-sensitive.</p>
- *
- * <p>Context keys and values may not be null or empty. A key/value will be
- * deemed empty if it's length is zero, or if it consists of only space
- * characters.</p>
- *
- * <p>Two default ContextSet implementations are provided.
- * {@link MutableContextSet} allows the addition and removal of context keys
- * after construction, and {@link ImmutableContextSet} does not.</p>

+/**
+ * A set of contexts.
+ *
+ * <p>Context in the most basic sense simply means the circumstances where
+ * something will apply.</p>
+ *
+ * <p>A single "context" consists of a key and a value, both strings. The key
+ * describes the type of the context, and the value represents what the key is
+ * set to.</p>
+ *
+ * <p>For example, a context with {@code key=world} and {@code value=world_nether}
+ * describes that a subject is in the "world_nether" world.</p>
+ *
+ * <p>Contexts are exposed to end users and manipulated when managing permissions.
+ * For this reason, context keys should strike a balance between being descriptive
+ * and succinct.</p>
+ *
+ * <p>Context keys and values are case-insensitive, and will be automatically
+ * converted to {@link String#toLowerCase() lowercase} when added to a
+ * context set. Keys and values cannot be null or empty (len=0 or consisting of
+ * only whitespace).</p>
+ *
+ * <p>If a context key is formed of more than one word, the parts should be
+ * separated by the '{@code -}' character. (e.g. "{@code server-type}")</p>
+ *
+ * <p>If a context key is likely to conflict with another plugin, it should be
+ * appropriately namespaced using the name of the plugin providing the context.
+ * The namespace should be at the start of the context key, and separated using
+ * the '{@code :}' character. (e.g. "{@code worldguard:region}" for WorldGuard
+ * regions)</p>
+ *
+ * <p>Contexts can be combined with each other to form so called
+ * "context sets" - simply a collection of context pairs.</p>
+ *
+ * <p>Two default ContextSet implementations are provided.
+ * {@link MutableContextSet} allows the addition and removal of context keys
+ * after construction, and {@link ImmutableContextSet} does not.</p>
