+
+Do you know that you can use Task without really needing to install it?
+
+If you work with Go, you probably depend on external binaries like linters,
+code generators and... Task.
+
+But asking your coworkers or contributors to install dependencies can be messy.
+Everyone is on a different operating system, use a different package manager,
+etc. In fact, [Task supports several package managers][install], but even having
+to choose how you want to install it can lead to some fatigue.
+
+Well, turns out you can just use `go tool`!
+
+Step one: add Task as a tool to your Go project:
+
+```bash
+go get -tool github.com/go-task/task/v3/cmd/task@latest
+```
+
+The command above will add a line like this to your `go.mod`:
+
+```
+tool github.com/go-task/task/v3/cmd/task
+```
+
+Step two: prefix `go tool` when calling Task:
+
+```bash
+go tool task {arguments...}
+```
+
+That's all!
+
+Go will compile the specified Task version on demand when calling `go tool task`.
+Don't worry, Go caches the tool, so subsequent calls are faster.
+
+This is useful when running Task on CI, as you don't need to stress about having
+to install it. It also means it'll be pinned to a specific Task version (but
+Dependabot or Renovate should be able to update it for you).

+## Go Tool
+
+If you're working in a Go project, a nice possibility is using `go tool`.
+`go tool` makes it easy to run Task without needing to install the binary
+manually. This works well on CI.
+
+To do that, just run the following to add Task as a tool in your Go project.
+Task will be added to your `go.mod`.
+
+```bash
+go get -tool github.com/go-task/task/v3/cmd/task@latest
+```
+
+Then, prefix `go tool` when calling Task like below. Go will compile Task on
+demand before calling it.
+
+```bash
+go tool task {arguments...}
