 # Eye of Nemesis
 Eye of Nemesis is a plugin that allows server admins to write policies that will deny or allow (black/whitelist) players to do specific things based on the value of nodes.
 
-## Warnings
-- Even though running `/eye` will tell you to run `/eye help` to list all available commands, this is not implemented yet, however all commands are available as tab-complete of `/eye`.
-- This plugin is in a very early stage.
-
 ## Motivations
 I made this plugin as an effort to preserve a village from my private server. Originally from beta 1.7.3 Betalands server, then transferred to RetroMC, and then finally we downloaded the chunks to merge into our server, I was afraid it would not have the same feeling after all the updates, so I had the idea to make a plugin that can block the newer features.
 
+## Game version and loaders
+Since version 1.0.3-SNAPSHOT, Eye of Nemesis has _reflection_, a technique that allows me to target multiple versions of the game while sharing the codebase across versions.
+
+Currently, we support the following Minecraft versions/loaders:
+- **PaperMC** `1.21, 1.21.1, 1.21.2, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10`
+- **Bukkit** `b1.7.3 (CB1060)`
+
 ## Performance
 This plugin is not scalable as it is and will end up running unoptimized checks when your players do things with policies in effect, I made it for a server with a few friends. I'll look forward into writing more performant code after all my other priorities are implemented.

+# Nodes
+Nodes narrow down even further if an action can be done or not. A node needs _properties_ to know what it should check against, for example, a HIT node needs a _list_ of blocks that it will check if the player is holding; while a USE_ENCHANTMENT node needs a mapping of enchantment to level. Some nodes like glyde don't need a value and will ignore if you provide one.
+```yaml
+nodes:
+  - [HIT]:
+      values:
+        - 'GOLD_SWORD'
+  - [USE_ENCHANTMENT]:
+      values:
+        - "UNBREAKING": "1"
+  - [GLYDE]
+```
+
+## Available nodes
+### INTERACT
+Triggered on `InteractionEvent`, returns true when the provided `list` contains the material used to interact.
+
+### HIT
+Triggered on `EntityDamageByEntityEvent`, returns true when the provided `list` contains the material used to hit.
+
+### PLACE
+Triggered on `BlockPlaceEvent`, returns true when the provided `list` contains the material being placed.
+
+### BREAK
+Triggered on `BlockBreakEvent`, returns true when the provided `list` contains the material used to break.
+
+### EQUIP
+Triggered on `InventoryClickEvent` and `PlayerInteractEvent` (only if item is an armor), returns true when the provided `list` contains the material being equipped.
+
+### GLYDE
+Triggered on `PlayerMoveEvent`, returns true if player is gliding.
+
+### USE_ENCHANTMENT
+Triggered on `BlockBreakEvent` and `onEntityDamageByEntityEvent`, returns true the used item has an enchantment matching the provided mapping of enchantment-level.

docs/Policies.md

+# Policies
+Policies are a list of nodes with a specific condition to be met, they also determine what effect a node is going to have. Below is an example policy:
+```yaml
+  - name: "Allow example"
+    type: "location"
+    effect: ALLOW
+    weight: 1
+    worlds: [world]
+    locations:
+      coordinates:
+        - corner1: { x: 2100, y: 256, z: 1400 }
+          corner2: { x: 1000, y: -64, z: 2200 }
+    nodes:
+      - [INTERACT, BREAK, HIT, PLACE]:
+          values:
+            - AIR
+```
+
+## Properties
+### `name`
+Name of the policy, must not contain spaces or else commands that require you to type the policy name will not work.
+
+Example: `name: "disable-axe-damage"`
+
+### `type`
+One of the policy [types](#Types).
+
+Example: `type: location`
+
+### `effect`
+Can be `deny` to block the action if a node check returns true, `ALLOW` to revert `DENY` effects if the node check is true or `ALLOWONLY` to allow the action **only** if the node check returns true.
+
+Example: `effect: DENY`
+
+### `weight`
+A policy with greater weight will override a conflicting policy of lower weight.
+
+Example: `weight: 0`
+
+### `nodes`
+Must contain a list of node mappings to evaluate if the policy applies to a player.
+
+Example:
+```yaml
+nodes:
+  - [HIT]:
+      values:
+        - '.*_AXE$'
+```
+
+### `locations`
+Only used for `type: "location"`, is a list of mappings where corner1 and corner2 should map x, y and z to two corners of a rectangular area where the policy will take effect; `worlds` may be defined here.
+
+Example:
+
+```yaml
+locations:
+  worlds: [world]
+  coordinates:
+    - corner1: { x: 2100, y: 256, z: 1400 }
+      corner2: { x: 1000, y: -64, z: 2200 }
+```
+
+### `permissions`
+Only used for `type: "permission"`, is a list of permissions.
+
+Example:
+
+```yaml
+permissions:
+  - "server.axehit"
+```
+
+### `names`
+Only used for `type: "playerName"`, is a list of player names.
+
+## Types
+
+### `global`
+Always matches.
+
+### `location`
+Matches if the player location is inside any rectangle defined in the `locations` property.
+
+### `playerName`
+Matches if the player name is in the `names` property.
+
+### `permission`
+Matches if the player has a permission in the `permissions` property.
