+# yamlfmt
+
+`yamlfmt` is an extensible command line tool or library to format yaml files. 
+
+## Goals
+
+* Create a command line yaml formatting tool that is easy to distribute (single binary)
+* Make it simple to extend with new custom formatters
+* Enable alternative use as a library, providing a foundation for users to create a tool that meets specific needs 
+
+## Maintainers
+
+This tool is not yet officially supported by Google. It is currently maintained solely by @braydonk, and unless something changes primarily in spare time.
+
+## Blog
+
+I'm going to use these links to GitHub Discussions as a blog of sorts, until I can set up something more proper:
+* yamlfmt's recent slow development [#149](https://github.com/google/yamlfmt/discussions/149)
+* Issues related to the yaml.v3 library [#148](https://github.com/google/yamlfmt/discussions/148)
+
+## Installation
+
+To download the `yamlfmt` command, you can download the desired binary from releases or install the module directly:
+```
+go install github.com/google/yamlfmt/cmd/yamlfmt@latest
+```
+This currently requires Go version 1.18 or greater.
+
+NOTE: Recommended setup if this is your first time installing Go would be in [this DigitalOcean blog post](https://www.digitalocean.com/community/tutorials/how-to-build-and-install-go-programs).
+
+You can also download the binary you want from releases. The binary is self-sufficient with no dependencies, and can simply be put somewhere on your PATH and run with the command `yamlfmt`.
+
+You can also install the command as a [pre-commit](https://pre-commit.com/) hook. See the [pre-commit hook](./docs/pre-commit.md) docs for instructions.
+
+## Basic Usage
+
+See [Command Usage](./docs/command-usage.md) for in-depth information and available flags.
+
+To run the tool with all default settings, run the command with a path argument:
+```bash
+yamlfmt x.yaml y.yaml <...>
+```
+You can specify as many paths as you want. You can also specify a directory which will be searched recursively for any files with the extension `.yaml` or `.yml`.
+```bash
+yamlfmt .
+```
+
+You can also use an alternate mode that will search paths with doublestar globs by supplying the `-dstar` flag. 
+```bash
+yamlfmt -dstar **/*.{yaml,yml}
+```
+See the [doublestar](https://github.com/bmatcuk/doublestar) package for more information on this format.
+
+# Configuration File
+
+The `yamlfmt` command can be configured through a yaml file called `.yamlfmt`. This file can live in your working directory, a path specified through a [CLI flag](./docs/command-usage.md#operation-flags), or in the standard global config path on your system (see docs for specifics).
+For in-depth configuration documentation see [Config](docs/config-file.md).
