As Minestom is a Java library, it must be loaded the same way any other Java library may be loaded.
This means you need to add Minestom as a dependency, add your code and compile by yourself.
For adding the required repositories and dependencies, [check this out](https://wiki.minestom.net/setup/dependencies)
`minestom-ce` is available on [Maven Central](https://central.sonatype.com/artifact/dev.hollowcube/minestom-ce),

# What is `minestom-ce`?
`minestom-ce` is a fork of `Minestom/Minestom` with some controversial/breaking changes. It was originally started as @mworzala's
personal fork for making changes, but has since been used by a number of others and aims to be relatively stable. The high
level goal of many changes are to make Minestom more of a library and less of a server implementation. For example:
* Removing extensions
* Removing logging & terminal implementations
The name "community edition" is not a reflection of an intentional rift between the two projects, it was just a joke between
a few people that stuck. I (@mworzala) am very happy for changes in `minestom-ce` to be merged back to `Minestom/Minestom`, I
just do not necessarily have the time to do so myself.
# Why Minestom?
Minecraft has evolved a lot since its release, most of the servers today do not take advantage of vanilla features and even have to struggle because of them.
Our target audience is those who want to make a server that benefits little from vanilla features. e.g. creative, kitpvp.

Commands are the simplest way of communication between clients and server. Since 1.13 Minecraft has incorporated a new library denominated "Brigadier", we then integrated an API designed to use the full potential of args types.

* Add `Tag.Transient`
* Optionally allow multiple parents in event nodes
* **breaking** Add sender to argument parsing chain
* This allows for argument parsing based on the sender, such as in argument map. This was already present for suggestions, but not for parsing.
* This is a breaking change because it changes the signature of `Argument#parse`, but most use cases should not be affected.
Support has been maintained for the old argument map signature, so only completely custom arguments will be affected.
