=== "Homebrew"
To install `func` using Homebrew, run the following commands:
```bash
brew tap knative-sandbox/kn-plugins
```
```bash
brew install func
```
If you have already installed the `kn` CLI by using Homebrew, the `func` CLI is automatically recognized as a plugin to `kn`, and can be referenced as `kn func` or `func` interchangeably.
!!! note
Use `brew upgrade` instead if you are upgrading from a previous version.
=== "Executable binary"
You can install `func` by downloading the executable binary for your system and placing it in the system path.
1. Download the binary for your system from the [`func` release page](https://github.com/knative/func/releases){target=_blank}.
1. Rename the binary to `func` and make it executable by running the following commands:
```bash
mv <path-to-binary-file> func
```
```bash
chmod +x func
```
Where `<path-to-binary-file>` is the path to the binary file you downloaded in the previous step, for example, `func_darwin_amd64` or `func_linux_amd64`.
1. Move the executable binary file to a directory on your PATH by running the command:
```bash
mv func /usr/local/bin
```
1. Verify that the CLI is working by running the command:
```bash
func version
```
=== "Go"
1. Check out the `func` client repository and navigate to the `func` directory:
```bash
git clone https://github.com/knative/func.git func
```
```bash
cd func/
```
1. Build an executable binary:
```bash
make
```
1. Move `func` into your system path, and verify that `func` commands are working properly. For example:
```bash
func version
```
=== "Container image"
Run `func` from a container image. For example:
```bash
docker run --rm -it ghcr.io/knative/func/func create -l node -t http myfunc
```
Links to images are available here:
- [Latest release](https://gcr.io/knative-releases/knative.dev/client/cmd/kn){target=_blank}
!!! note
Running `func` from a container image does not place the binary on a permanent path. This procedure must be repeated each time you want to use `func`.
