+# Contraband System
+## Overview
+Contraband System is the system that defines what contraband is in-character. As of now (when I am writing this doc), it is a detailed examine showing 2 things: type of contraband (departmental-restricted, minor, major, syndicate) and whether or not the wearer ID allows the person to possess this contraband. 
+
+## Background
+Contraband system was initially added in [#28688](https://github.com/space-wizards/space-station-14/pull/28688). The main reason for this systems was to improve security work by strictly defining contraband. Shortly after, the Space Law was changed in [#30937](https://github.com/space-wizards/space-station-14/pull/30937), changing manual listing to a reference to the in-game system.
+Afterwards, many small-scale PRs were made in order to adjust contraband markings. 
+With the addition of magical contraband in [#35254](https://github.com/space-wizards/space-station-14/pull/35254), addition of job-specific contraband in [#33385](https://github.com/space-wizards/space-station-14/pull/33385) and changes to contraband examine in [#32250](https://github.com/space-wizards/space-station-14/pull/32250), several discussions took place about the desired behavior of the system.
+
+## Technical info
+Contraband System relies on ContrabandComponent in order to store all information about contraband status.
+To simplify prototyping, abstract prototypes have been created for base contraband types, for example:
+```yaml
+- type: entity
+  id: BaseSecurityBartenderContraband
+  parent: BaseRestrictedContraband
+  abstract: true
+  components:
+  - type: Contraband
+    allowedDepartments: [ Security ]
+    allowedJobs: [ Bartender ]
+
+- type: entity
+  id: BaseMajorContraband
+  abstract: true
+  components:
+  - type: Contraband
+    severity: Major
+```
+Severity here refers to the ContrabandSeverityPrototype, which can be defined like this:
+```yaml
+- type: contrabandSeverity
+  id: Minor
+  examineText: contraband-examine-text-Minor
+```
+In order to designate an object as contraband, assign one of the base contraband types as a parent. Here's an example with the security HUD: BaseSecurityContraband as a parent automatically adds the contraband designation.
+```yaml
+- type: entity
+  parent: [ClothingEyesBase, ShowSecurityIcons, BaseSecurityContraband]
+  id: ClothingEyesHudSecurity
+  name: security hud
+  description: A heads-up display that scans the humanoids in view and provides accurate data about their ID status and security records.
+  components:
+  - type: Sprite
+    sprite: Clothing/Eyes/Hud/sec.rsi
+  - type: Clothing
+    sprite: Clothing/Eyes/Hud/sec.rsi
+  - type: Tag
+    tags:
+    - HudSecurity
+```
+## Intended Experience
+- Help security to solve conflicts like "I found it it maints, therefore it's legal" and "Not everything with syndicate mention in the name is illegal" using in-character means;
+- Be an easy way to determine if using this item as security or command will be in breach of the rules;
+- Help admins settle conflicts where items are being confiscated by security (lawfully or unlawfully).
+## Experience To Avoid
+- Starting OOC conflicts about legal status of an item;
+- Uncovering stealth items;
+- Blocking possibility of delegations and exceptions (like captain giving the sabre to HoS due to being a pacifist, or using syndicate contraband as a last resort against nukies).
