+
+Namespaces are identifiers that mark content ownership. You can think of them as folders. Namespaces are helpful because they keep naming conflicts from happening.
+
+Namespaces in addon creation can essentially be thought of as "the part to the left of the colon". For example, `minecraft` is the namespace of `minecraft:zombie`. The general form is `namespace:name`.
+
+As a concrete example of why namespaces are helpful, let's imagine you create a new Mob. You name it `minecraft:shark`, not aware that you should create your own namespace for custom content. Next year, Mojang decides to add sharks into the game! Now there is a naming conflict since there are two definitions of `minecraft:shark`. Your addon will break.
+
+If you had instead used `your_namespace:shark`, the naming conflict wouldn't have happened.
+
+## Picking a namespace
+
+A suitable namespace is unique to you. Something like `mob` or `cars` or `content` or `custom` would be a **bad** namespace since another developer might come up with the same namespace as you.
+
+A suitable namespace is short. You will be writing your namespace a **LOT**, so the shorter, the better. `george_carlin_the_comedian` would be a lousy namespace for this reason.
+
+For personal projects, I recommend a convenient version of your player name, and for commercial projects, I recommend a suitable version of the company name.
+
+Some good examples:
+
+-   `gcarlin`
+-   `sirlich`
+-   `cubeworld`
+-   `bworks`
+
+**DO NOT USE** `minecraft` or `minecon` as a namespace unless editing a vanilla file. Not only is it a terrible idea, but Minecraft reserves these, and it won't even work.
+
+## Where to use namespaces?
+
+In short, you should use namespaces as often as you can.
+
+For starters, you should use a namespace when adding custom entities to the game.
+
+`sirlich:shark` is much better than `shark`.
+
+It would be best if you also used namespaces for components and events. Just like Mojang uses `minecraft:pig_saddled` you should use `namespace:my_mob_event`, and `namespace:my_component_group`.
+
+It would be best if you also used namespaces in animation controllers, render controllers, and animations.
+
+For example: `controller.animation.namespace.entity_name.action` is better than `controller.animation.my_action`.
+
+## Where NOT to use namespaces.
+
+The actual file structure does not need namespaces.
+
+`animations/namespace/my_entity/animation` is more confusing than `animations/my_entity/animation`.
