+The completion script must be evaluated to provide interactive
+completion. This can be done by sourcing it from your shell profile.

+Bash:
+    source <({{.CLIName}} completion bash)

+    # To load completions for each session, execute once:
+    # Linux:
+    {{.CLIName}} completion bash > /etc/bash_completion.d/{{.CLIName}}
+    # macOS:
+    {{.CLIName}} completion bash > /usr/local/etc/bash_completion.d/{{.CLIName}}
+
+Zsh:
+    # If shell completion is not already enabled, enable it:
+    echo "autoload -U compinit; compinit" >> ~/.zshrc
+
+    # To load completions for each session, execute once:
+    {{.CLIName}} completion zsh > "${fpath[1]}/_{{.CLIName}}"
+
+    # You will need to start a new shell for this setup to take effect.
+
+Fish:
+    {{.CLIName}} completion fish | source
+
+    # To load completions for each session, execute once:
+    {{.CLIName}} completion fish > ~/.config/fish/completions/{{.CLIName}}.fish
+
+PowerShell:
+    {{.CLIName}} completion powershell | Out-String | Invoke-Expression
+
+    # To load completions for every new session:
+    {{.CLIName}} completion powershell > {{.CLIName}}.ps1
+    # and source this file from your PowerShell profile.
