+# Task - Simple "Make" alternative
+
+Task is a simple tool that allows you to easily run development and build
+tasks. Task is written in Go, but can be used to develop any language.
+It aims to be simpler and easier to use then [GNU Make][make].
+
+## Installation
+
+If you have a Go environment setup, you can simply run:
+
+```bash
+go get -u -v github.com/go-task/task/cmd/task
+```
+
+Now the `task` executable should be available in your `PATH`.
+
+## Usage
+
+Create a file called `Taskfile.yml`. The `cmds` key should contains the
+commands of a task:
+
+```yml
+build:
+  cmds:
+    - go build -v -i main.go
+
+assets:
+  cmds:
+    - gulp
+```
+
+Running the tasks is as simple as running:
+
+```bash
+task assets build
+```
+
+If Bash is available (Linux and Windows while on Git Bash), the commands will
+run in Bash, otherwise will run on `cmd` (Windows).
+
+### Task dependencies
+
+You may have tasks that depends on others. Just point them on `deps` will run
+them automatically:
+
+```yml
+build:
+  deps: [assets]
+  cmds:
+    - go build -v -i main.go
+
+assets:
+  cmds:
+    - gulp
+```
+
+In the above example, `assets` will always run right before `build` if you run
+`task build`.
+
+A task can have only dependencies and no commands to group tasks together:
+
+```yml
+assets:
+  deps: [js, css]
+
+js:
+  cmds:
+    - npm run buildjs
+
+css:
+  cmds:
+    - npm run buildcss
+```
+
+### Prevent task from running when not necessary
+
+If a task generates something, you can inform Task the source and generated
+files, to Task will prevent to run them if not necessary.
+
+```yml
+build:
+  deps: [js, css]
+  cmds:
+    - go build -v -i main.go
+
+js:
+  cmds:
+    - npm run buildjs
+  sources:
+    - js/src/**/*.js
+  generates:
+    - public/bundle.js
+
+css:
+  cmds:
+    - npm run buildcss
+  sources:
+    - css/src/*.css
+  generates:
+    - public/bundle.css
+```
+
+`sources` and `generates` should be file patterns. When both are given, Task
+will compare the modification date/time of the files to determine if it's
+necessary to run the task. If not, it will just print
+`Task "js" is up to date`.
