-## Usage Documentation
+## Documentation
 
-Usage documentation exists for each major version. Don't know what version you're on? You're probably using the version from the `main` branch, which is currently `v2`.
-
-- `v2` - [./docs/v2/manual.md](./docs/v2/manual.md)
-- `v1` - [./docs/v1/manual.md](./docs/v1/manual.md)
-
-Guides for migrating to newer versions:
-
-- `v1-to-v2` - [./docs/migrate-v1-to-v2.md](./docs/migrate-v1-to-v2.md)
-
-## Installation
-
-Using this package requires a working Go environment. [See the install instructions for Go](http://golang.org/doc/install.html).
-
-Go Modules are required when using this package. [See the go blog guide on using Go Modules](https://blog.golang.org/using-go-modules).
-
-### Using `v2` releases
-
-```
-$ go get github.com/urfave/cli/v2
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli/v2" // imports as package "cli"
-)
-...
-```
-
-### Using `v1` releases
-
-```
-$ go get github.com/urfave/cli
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli"
-)
-...
-```
-
-### Build tags
-
-You can use the following build tags:
-
-#### `urfave_cli_no_docs`
-
-When set, this removes `ToMarkdown` and `ToMan` methods, so your application
-won't be able to call those. This reduces the resulting binary size by about
-300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to fewer dependencies.
-
-### GOPATH
-
-Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can
-be easily used:
-```
-export PATH=$PATH:$GOPATH/bin
-```
-
-### Supported platforms
-
-cli is tested against multiple versions of Go on Linux, and against the latest
-released version of Go on OS X and Windows. This project uses Github Actions for
-builds. To see our currently supported go versions and platforms, look at the [./.github/workflows/cli.yml](https://github.com/urfave/cli/blob/main/.github/workflows/cli.yml).
+More documentation is available in [`./docs`](./docs) or the hosted
