   goreleaser: Deliver Go binaries as fast and easily as possible
 ---
 
-### Updating `goreleaser`
+To update or switch versions, run `webi goreleaser@stable` (or `@v0.174`,
+`@beta`, etc).
 
-`webi goreleaser@stable`
+## Cheat Sheet
 
-Use the `@beta` tag for pre-releases.
+> `goreleaser` makes it easy to build versioned Go binaries for Mac, Linux,
+> Windows, and Raspberry Pi, and to publish the ChangeLog and binaries to common
+> release platforms including GitHub, Gitea, Gitlab, and Homebrew.
 
-## Cheat Sheet
+There's a lot that you can do with GoReleaser. These are the things that we've
+found the most useful for the majority of projects:
+
+- Basic Usage & Versioning
+- Publishing Builds to GitHub
+- Publishing to Gitea and Gitlab
+- Building for RPi et al
+- Building from one or more `cmd/`s
+- Cross-Compiling with cgo
+- Full `.goreleaser.yml` example
+
+## Basic Usage & Versioning
+
+To create an example `.goreleaser.yaml` file, and test the configuration:
+
+```bash
+goreleaser init
+goreleaser --snapshot --skip-publish --rm-dist
+```
+
+- `--snapshot` allows "dirty" builds (when the repo has uncommitted changes)
+- `--skip-publish` will NOT publish to GitHub, etc
+- `--rm-dist` will automatically remove the `./dist/` directory
+
+The default `.goreleaser.yml` works well for projects for which `package main`
+is at the root.
+
+GoReleaser provides version information. Here's a good, generic way to print it
+out:
+
+```go
+package main
+
+var (
+       // these will be replaced by goreleaser
+       version = "v0.0.0"
+       date    = "0001-01-01T00:00:00Z"
+       commit  = "0000000"
+)
+
+func main() {
+       if len(os.Args) >= 2 && "version" == strings.TrimPrefix(os.Args[1]) {
+               fmt.Printf("YOUR_CLI_NAME v%s %s (%s)\n", version, commit[:7], date)
+       }
+
+       // ...
+}
+```
+
+### How to Publish Builds to GitHub
+
+You'll need a **Personal Access Token** with the `repo` scope. \
+You can get one at <https://github.com/settings/tokens/new>.
+
+You can export the environment variable:
+
+```bash
+export GITHUB_TOKEN="YOUR_GITHUB_TOKEN"
+```
+
+Or place the token in the default config location:
+
+```bash
+~/.config/goreleaser/github_token
+```
+
+You can also set `env_files` in `.goreleaser.yml`:
+
+```yml
+env_files:
+  github_token: ~/.config/goreleaser/github_token
+```
+
+Running GoReleaser without `--snapshot` must use the latest
+[Git tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging) of your repository.
+Create a tag and push it to Git:
+
+```bash
+git tag -a v1.0.0 -m "First release"
+git push origin v1.0.0
+```
+
+Running GoReleaser without `--skip-publish` will publish the builds:
+
+```bash
+goreleaser --rm-dist
+```
+
+Check the console output to make sure that there are no messages about a failed
+publish. \
+If all is well you should the git tag on the releases page updated with a ChangeLog
+and the published binaries.
+
+### How to Publish to Gitea and others
+
+Gitea Token: https://try.gitea.io/user/settings/applications
 
-> `goreleaser` doesn't exist and this text should have been replaced. It doesn't do
-> anything, but what it does is useful because it is; everybody knows it.
+```yml
+env_files:
+  gitea_token: ~/.config/goreleaser/gitea_token
+gitea_urls:
+  api: https://try.gitea.io/api/v1/
+```
+
+GitLab Token: https://gitlab.com/profile/personal_access_tokens
+
+```yml
+env_files:
+  gitlab_token: ~/.config/goreleaser/gitlab_token
+gitlab_urls:
+  api: https://gitlab.com/api/v1/
+```
+

+
+### How to Build for Raspberry Pi (ARM)
+
+All of the Raspberry Pis are ARM processors and can run Linux. Most can run
+Windows as well.
+
+- RPi 4 is ARM 64, also known as `aarch64`, `arm64`, and `armv8`.
+- RPi 3 could run `armv7` and `arm64`.
+- RPi 2, RPi Zero, and RPi can run either `armv6` or `armv7`.
+
+To build Go binaries for ARM, you'll need to update the `build` section of your
+`.goreleases.yml`.
+
+```yml
+builds:
+  - env:
+      - CGO_ENABLED=0
+    goos:
+      - linux
+      - windows
+      - darwin
+    goarch:
+      - 386
+      - amd64
+      - arm
+      - arm64
+    goarm:
+      - 6
+      - 7
+```
+
+For information on other supported build options, such as BSD and ppc, see
+[Go (Golang) GOOS and GOARCH](https://gist.github.com/asukakenji/f15ba7e588ac42795f421b48b8aede63).
+
+### How to Build from the `cmd` Directory
+
+By default GoReleaser assumes that the root of your package is `package main`.
+
+If your `package main` is in a `cmd/` directory or you have multiple commands,
+you should update your `builds` directive accordingly.
+
+```yml
+- builds:
+    - id: command123
+      main: ./cmd/command123/command123.go
+      binary: command123
+      goos:
+        - linux
+        - windows
+        - darwin
+      goarch:
+        - amd64
+        - arm64
+    - id: other321
+      main: ./cmd/other321/other321.go
+      binary: other123
+      goos:
+        - linux
+        - windows
+        - darwin
+      goarch:
+        - amd64
+        - arm64
+```
+
+### How to Cross-Compile cgo
+
+> [cgo](https://golang.org/cmd/cgo/) is not Go - Dave Cheney
+
+Most Go programs are "pure Go" and will cross-compile `CGO_ENABLED=0` without
+any special configuration.
 
-To run goreleaser:
+Some programs include C libraries, especially SQLite3 or 7z, and require
+integration with C libraries.
+
+#### Mac Cross-Compilers
+
+From macOS you can easily cross-compile cgo for Windows and Linux.
+
+Install [brew](https://webinstall.dev/brew), if needed:
+
+```bash
+curl -sS https://webinstall.dev/brew | bash
+```
+
+Install mingw and musl-cross: \
+(this may take hours if pre-built binaries are not available)
+
+```bash
+brew install mingw-w64
+brew install FiloSottile/musl-cross/musl-cross --with-aarch64 --with-arm # --with-mips --with-486
+```
+
+You may want to manually test compiling for multiple platforms before automating
+it:
 
 ```bash
-goreleaser
+GOARCH=amd64 GOOS=darwin                              go build -o unarr_darwin cmd/unarr/unarr.go
+GOARCH=amd64 GOOS=windows CC=x86_64-w64-mingw32-gcc   go build -o unarr.exe cmd/unarr/unarr.go
+GOARCH=amd64 GOOS=linux   CC=x86_64-linux-musl-gcc    go build -o unarr_linux_amd64 cmd/unarr/unarr.go
+GOARCH=arm64 GOOS=linux   CC=aarch64-linux-musl-gcc   go build -o unarr_linux_arm64 cmd/unarr/unarr.go
+GOARCH=arm   GOOS=linux   CC=arm-linux-musl-gcc       go build -o unarr_linux_armv7 cmd/unarr/unarr.go
 ```
 
-### Add Baz Highlighting
+If you have simple instructions for how to set up cross-compiling from Windows
+or Linux, please let us know.
+
+#### Build Changes
+
+You'll need to manually create a different `builds` item for each unique `id`:
+
+```yml
+- builds:
+    - id: unarr-linux-x64
+      main: ./cmd/unarr/unarr.go
+      env:
+        - CGO_ENABLED=1
+        - CC=x86_64-linux-musl-gcc
+      flags:
+        - '-ldflags'
+        - '-extldflags "-static"'
+      goos:
+        - linux
+      goarch:
+        - amd64
+    - id: unarr-linux-aarch64
+      main: ./cmd/unarr/unarr.go
+      env:
+        - CGO_ENABLED=1
+        - CC=aarch64-linux-musl-gcc
+      flags:
+        - '-ldflags'
+        - '-extldflags "-static"'
+      goos:
+        - linux
+      goarch:
+        - arm64
+    - id: unarr-linux-armv7
+      main: ./cmd/unarr/unarr.go
+      env:
+        - CGO_ENABLED=1
+        - CC=arm-linux-musleabi-gcc
+      flags:
+        - '-ldflags'
+        - '-extldflags "-static"'
+      goos:
+        - linux
+      goarch:
+        - arm
+      goarm:
+        - 7
+    - id: unarr-windows-x64
+      main: ./cmd/unarr/unarr.go
+      env:
+        - CGO_ENABLED=1
+        - CC=x86_64-w64-mingw32-gcc
+      flags:
+        - '-ldflags'
+        - '-extldflags "-static"'
+      goos:
+        - linux
+      goarch:
+        - amd64
+```
 
-To run goreleaser with both bar and baz highlighting turned on:
+If you compile without `-static`, you will need the `musl` libraries to run on
+(non-Alpine) Linuxes:
 
 ```bash
-goreleaser --bar=baz
+sudo apt-get install -y musl
+```
+
+### Full Example Config
+
+The full file will look something like this:
+
+`.goreleaser.yml`
+
+```yml
+project_name: exampleproject
+before:
+  hooks:
+    - go mod download
+    - go generate ./...
