 ## Introduction
 
 `evolved.lua` is a fast and flexible ECS (Entity-Component-System) library for Lua. It is designed to be simple and easy to use, while providing all the features needed to create complex systems with blazing performance.

 On the other hand, `evolved.lua` tries to be minimalistic and does not provide features that can be implemented outside the library. I'm trying to find a balance between minimalism and the number of possibilities, which forces me to make flexible decisions in the library's design. I hope you will find this balance acceptable.
 
+## Requirements
+
+- [lua](https://www.lua.org/) **>= 5.1**
+- [luajit](https://luajit.org/) **>= 2.0**

 ## Installation
 
-`evolved.lua` is a single-file pure Lua library and does not require any external dependencies. It is designed to work with [Lua 5.1](https://www.lua.org/) and later, [LuaJIT](https://luajit.org/), and [Luau](https://luau.org/) (Roblox).
-
-All you need to start using the library is the [evolved.lua](./evolved.lua) source file. You can download it from the [releases](https://github.com/BlackMATov/evolved.lua/releases) page or clone the [repository](https://github.com/BlackMATov/evolved.lua) and copy the file to your project.
-
-If you are using [LuaRocks](https://luarocks.org/), you can install the library using the following command:

 ## Quick Start
 
-To get started with `evolved.lua`, read the [Overview](#overview) section to understand the basic concepts and how to use the library. After that, check the [Example](develop/example.lua), which demonstrates complex usage of the library.

 All of these functions can be safely called on non-alive entities and non-alive fragments. Also, they do not cause any structural changes, because they do not modify anything.
 
-### Iterating Over Fragments
-
-Sometimes, you may need to iterate over all fragments attached to an entity. You can use the [`evolved.each`](#evolvedeach) function for this purpose.
-
-```lua
-local evolved = require 'evolved'
-
-local health = evolved.builder()
-    :name('health')
-    :spawn()
-
-local stamina = evolved.builder()

-local player = evolved.builder()
-    :set(health, 100)
-    :set(stamina, 50)

-for fragment, component in evolved.each(player) do

-        evolved.name(fragment), component))
-end
-```

-> [!NOTE]
-> [Structural changes](#structural-changes) are not allowed during iteration. If you want to spawn new entities or insert/remove fragments while iterating, defer these operations until the iteration is complete. See the [Deferred Operations](#deferred-operations) section for more details.

 ### Modifying Operations

-If you don't specify a query for the system, the system itself will be treated as a query. This means the system can contain `evolved.INCLUDES` and `evolved.EXCLUDES` fragments, and it will be processed according to them. This is useful for creating systems with unique queries that don't need to be reused in other systems.
-
-```lua
-local evolved = require 'evolved'
-
-local health = evolved.id()
-
-local system = evolved.builder()
-    :include(health)
-    :execute(function(chunk, entity_list, entity_count)
-        local health_components = chunk:components(health)

 To group systems together, you can use the [`evolved.GROUP`](#evolvedgroup) fragment. Systems with a specified group will be processed when you call the [`evolved.process`](#evolvedprocess) function with this group. For example, you can group all physics systems together and process them in one [`evolved.process`](#evolvedprocess) call.

Execution callbacks are called in the [deferred scope](#deferred-operations), which means that all modifying operations inside the callback will be queued and applied after the system has processed all chunks. But prologue and epilogue callbacks are not called in the deferred scope, so all modifying operations inside them will be applied immediately. This is done to avoid confusion and to make it clear that prologue and epilogue callbacks are not part of the chunk processing.

-#### Fragment Requirements
-
-Sometimes you want to add additional fragments to an entity when it receives a specific fragment. For example, you might want to add `position` and `velocity` fragments when an entity is given a `physical` fragment. This can be done using the [`evolved.REQUIRES`](#evolvedrequires) fragment trait. This trait expects a list of fragments that will be added to the entity when the fragment is inserted.

-
 #### Destruction Policies
 
 Typically, fragments remain alive for the entire lifetime of the program. However, in some cases, you might want to destroy fragments when they are no longer needed. For example, you can use some runtime entities as fragments for other entities. In this case, you might want to destroy such fragments even while they are still attached to other entities. Since entities cannot have destroyed fragments, a destruction policy must be applied to resolve this. By default, the library will remove the destroyed fragment from all entities that have it.

 ## Backlog
 
-- Improve the performance of required fragments by caching first-level required chunks.
-- Improve the performance of builders that are used multiple times by caching hint chunks.
-- Queries can cache major chunks to avoid finding them every time.
-- Should we make one builder:build method instead of :spawn and :clone?
-- Add multi-spawn to the builder to spawn multiple entities at once.
-- Add a function to shrink storages to free unused memory.
-- Should we cache the result of without_unique_fragments to clone faster?
+## After first release
+
+- cached queries
 - observers and events
 - add INDEX fragment trait
+- add REQUIRES fragment trait
 - use compact prefix-tree for chunks
 - optional ffi component storages
-- add EXCLUSIVE fragment trait
