 [![PkgGoDev](https://pkg.go.dev/badge/golang.org/x/tools)](https://pkg.go.dev/golang.org/x/tools)
 
-This subrepository holds the source for various packages and tools that support
-the Go programming language.
+This repository provides the `golang.org/x/tools` module, comprising
+various tools and packages mostly for static analysis of Go programs,
+some of which are listed below.
+Use the "Go reference" link above for more information about any package.
 
-Some of the tools, `godoc` and `vet` for example, are included in binary Go
-distributions.
+It also contains the
+[`golang.org/x/tools/gopls`](https://pkg.go.dev/golang.org/x/tools/gopls)
+module, whose root package is a language-server protocol (LSP) server for Go.
+An LSP server analyses the source code of a project and
+responds to requests from a wide range of editors such as VSCode and
+Vim, allowing them to support IDE-like functionality.
 
-Others, including the Go `guru` and the test coverage tool, can be fetched with
-`go install`.
+<!-- List only packages of general interest below. -->
 
-Packages include a type-checker for Go and an implementation of the
-Static Single Assignment form (SSA) representation for Go programs.
+Selected commands:
 
-## Download/Install
+- `cmd/goimports` formats a Go program like `go fmt` and additionally
+  inserts import statements for any packages required by the file
+  after it is edited.
+- `cmd/callgraph` prints the call graph of a Go program.
+- `cmd/digraph` is a utility for manipulating directed graphs in textual notation.
+- `cmd/stringer` generates declarations (including a `String` method) for "enum" types.
+- `cmd/toolstash` is a utility to simplify working with multiple versions of the Go toolchain.
 
-The easiest way to install is to run `go install golang.org/x/tools/...@latest`.
+These commands may be fetched with a command such as
+`go install golang.org/x/tools/cmd/goimports@latest`.
 
-## JS/CSS Formatting
+Selected packages:
+
+- `go/ssa` provides a static single-assignment form (SSA) intermediate
+  representation (IR) for Go programs, similar to a typical compiler,
+  for use by analysis tools.
+
+- `go/packages` provides a simple interface for loading, parsing, and
+  type checking a complete Go program from source code.
+
+- `go/analysis` provides a framework for modular static analysis of Go
+  programs.
+
+- `go/callgraph` provides call graphs of Go programs using a variety
+  of algorithms with different trade-offs.
+
+- `go/ast/inspector` provides an optimized means of traversing a Go
+  parse tree for use in analysis tools.
+
+- `go/cfg` provides a simple control-flow graph (CFG) for a Go function.
+
+- `go/expect` reads Go source files used as test inputs and interprets
+  special comments within them as queries or assertions for testing.
+
+- `go/gcexportdata` and `go/gccgoexportdata` read and write the binary
+  files containing type information used by the standard and `gccgo` compilers.
+
+- `go/types/objectpath` provides a stable naming scheme for named
+  entities ("objects") in the `go/types` API.
+
+Numerous other packages provide more esoteric functionality.
+
