# Setup & Environment

Antidote requires Erlang 21 or greater. Make sure the command `erl` is executable in your console.

Use the following `Makefile` targets to build and test antidote:

```
# compile the project:
make compile

# run the unit tests:
make test

# run the system tests:
make systests

# run the release test:
make reltest

# run dialyzer to check types:
make dialyzer

# run linter
make lint

# open a shell:
make shell

# build a release:
make rel
```

## Working on dependencies

When working on dependencies of Antidote it can be helpful to use them as [Checkout Dependencies](https://www.rebar3.org/docs/dependencies#section-checkout-dependencies):

* Create a folder named `_checkouts` in your `antidote` folder (next to the `_build` folder)
* Clone or symlink the dependency into that folder. The folder name in `_checkouts` must be the name of the dependency in `rebar.config`.
* When running a rebar3 task on Antidote, it will always use the latest version from the dependencies. 

  It will also recompile all other dependencies, which can be avoided [by patching rebar3](https://github.com/erlang/rebar3/issues/2152)
