 Boundary's CLI has predictable behavior throughout its various commands. This page details the common patterns in used in order to help users make better use of the CLI.
 
+## Completion
+
+Before detailing how parameters work, it's useful to note that Boundary's CLI supports autocompletion, which allows tab completion of commands, flags, and in some cases the parameters to those flags.
+
+This can be installed via the CLI itself:
+
+`boundary config autocomplete install`
+
+If you want to install it manually, for Bash, the following line in a `~/.bash_profile` or similar file will work:
+
+`complete -C /path/to/boundary boundary`
+
 ## Parameter Handling
 
 All parameters specified on the CLI are specified as a Go-style flag with a single dash, e.g. `-id`. The arguments to those flags can be specified via an equals sign, as in `-id=r_1234567890`, or a space, like `-id r_1234567890`.

 This allows the CLI to perform proper presentation and validation of parameters and functions for the given type.
 
 Similar to `read`, `update` operates on an existing target so will always take an `-id` parameter. Similar to `list`, `create` operates on a collection so will either take a `-scope-id` parameter or a parameter defining the parent resource.

+Boundary has a Go SDK that sports full coverage of Boundary's API. This SDK is mostly auto-generated so the patterns are predictable from package to package; for the most part, browsing [pkg.go.dev](https://pkg.go.dev/github.com/hashicorp/boundary/api) is a great way to get started.
