# Task
Task is a task runner / build tool that aims to be simpler and easier to use
than, for example, [GNU Make][make].
Since it's written in [Go][go], Task is just a single binary and has no other
dependencies, which means you don't need to mess with any complicated install
setups just to use a build tool.
Once [installed](installation.md), you just need to describe your build tasks
using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
```yaml
version: '3'
tasks:
hello:
cmds:
- echo 'Hello World from Task!'
silent: true
```
And call it by running `task hello` from you terminal.
The above example is just the start, you can take a look at the [usage](usage.md)
guide to check the full schema documentation and Task features.
## Features
- [Easy installation](installation.md): just download a single binary, add to
$PATH and you're done! Or you can also install using [Homebrew][homebrew],
[Snapcraft][snapcraft], or [Scoop][scoop] if you want;
- Available on CIs: by adding [this simple command](installation.md#install-script)
to install on your CI script and you're done to use Task as part of your CI pipeline;
- Truly cross-platform: while most build tools only work well on Linux or macOS,
Task also supports Windows thanks to [this awesome shell interpreter for Go][sh];
- Great for code generation: you can easily [prevent a task from running](usage.md#prevent-unnecessary-work)
if a given set of files haven't changed since last run (based either on its
timestamp or content).
