# 2 Install the CDT

This section provides guidance on how to install `cyberway.cdt` tools on your server.

The CyberWay Contract Development Toolkit (CyberWay CDT) is based on EOSIO CDT and is a collection of tools related to contract compilation. CyberWay CDT is primarily used for compiling contracts and generating ABI.

It is recommended to build and debug contracts on a specific server. Therefore, the server where CDT is installed, must meet the following characteristics (or above):

* RAM size (a min. of): 8 GB
* disk space (a min. of): 20 GB

One of the following operating systems must also be installed on the server:

* Ubuntu 16.04
* Ubuntu 18.04
* MacOS Darwin 10.12 (or later versions)
* Centos 7
* Fedora 25 (or later versions)
* Mint 18

**Attention**

* If you have previously installed CyberWay.CDT, run the `uninstall.sh` script (it is in the root of CyberWay.CDT repository) before downloading and using the binary releases.

## Install cyberway.cdt on local server

Installing `cyberway.cdt` requires you to perform the following actions:\
1\. Cloning the `cyberway.cdt` repository to your server\
2\. Building binaries\
3\. Tools installation

The last two actions are performed by scripts `build.sh` and `install.sh` located in the root of `cyberway.cdt`. These scripts are universal and designed for all operating systems supported by the CyberWay platform.

### Clone the cyberway.cdt repository

The location where `cyberway.cdt` is cloned is not that important because `cyberway.cdt` will be installing as a local binary in later steps. You can clone `cyberway.cdt` to "contracts" directory previously created or to any other location on your local system that is fit.

```bash
 $ cd CONTRACTS_DIR
 $ git clone --recursive https://github.com/cyberway/cyberway.cdt
```

### Build binaries

```bash
 $ cd cyberway.cdt
 $ ./build.sh
```

### Install tools

```bash
 $ sudo ./install.sh
```

The following tools will be installed to your local machine:

* cyberway-abidiff
* cyberway-cpp
* eosio-abigen
* eosio-cc
* eosio-init
* eosio-ld
* eosio-objcopy
* eosio-pp
* eosio-wasm2wast
* eosio-wast2wasm
* llvm-ar
* llvm-nm
* llvm-objdump
* llvm-ranlib
* llvm-readelf
* llvm-readobj
* llvm-strip

### Uninstall

```bash
 $ cd cyberway.cdt
 $ sudo ./uninstall.sh
```

The `install.sh` and `uninstall.sh` scripts need to be ran with `sudo` because various binaries of `cyberway.cdt` will be installed locally. It needs to be typed computer's account password.

## Important

Installing `cyberway.cdt` will make the compiled binary global, therefore it can be accessable anywhere. For this tutorial, it is strongly suggested that you do not skip the install step for `cyberway.cdt`, failing to install will make it more difficult to follow this and other tutorials and make usage more difficult in general.
