-## How to use
+## Usage
 
 - Prepare [GoReleaser](https://goreleaser.com/intro/) configuration
 
-- Generate environment variable `PRIVATE_KEY` from the GPG private key (optional), if enable the [signing](https://goreleaser.com/customization/sign/) feature
+- Set up GPG signing (optional), if enable the [signing](https://goreleaser.com/customization/sign/) feature
 
   ```bash
   export PRIVATE_KEY=$(cat ~/private_key.gpg | base64)
   ```
 
-- Run docker container to build the binaries
-
+- Build the binaries:
   ```bash
-    export GO_BUILDER_VERSION=v1.17.1
-    docker run --rm --privileged \
-      -e PRIVATE_KEY=$(PRIVATE_KEY) \
-      -v $(CURDIR):/golang-cross-example \
-      -v /var/run/docker.sock:/var/run/docker.sock \
-      -v $(GOPATH)/src:/go/src \
-      -w /golang-cross-example \
-      ghcr.io/gythialy/golang-cross:$(GO_BUILDER_VERSION) --snapshot --rm-dist
+  export GO_BUILDER_VERSION=v1.17.1;
