 [`github.com/markbates/pkger`](https://godoc.org/github.com/markbates/pkger) is a tool for embedding static files into Go binaries. It will, hopefully, be a replacement for [`github.com/gobuffalo/packr/v2`](https://godoc.org/github.com/gobuffalo/packr/v2).
 
-## How it Works
+### Requirements
+
+* Go 1.13+
+* Go Modules
+
+## How it Works (Module Aware Pathing)
 
 Pkger is powered by the dark magic of Go Modules, so they're like, totally required.

 * Packages can specified in at the beginning of a path with a `:` seperator.
 github.com/markbates/pkger:/cmd/pkger/main.go
 * There are no relative paths. All paths are absolute to the modules root.
+* Fully-qualified paths are embedded into the metadata of your static assets. If this behavior is undesirable, a preference is to build in a containerized environ, like docker, where the path strings are not ex-filtrating data about your development environment.

+"github.com/gobuffalo/buffalo:/go.mod" => /go/pkg/mod/github.com/gobuffalo/buffalo@v0.14.7/go.mod
 ```
 
-## Usage
+## CLI
+
+### Installation
+
+```bash
+$ go get github.com/markbates/pkger/cmd/pkger
+$ pkger -h
+```
+
+### Usage
+
+```bash
+$ pkger
+```
+
+The result will be a `pkged.go` file in the **root** of the module with the embedded information and the package name of the module.
+
+```go
+// ./pkged.go
+package <.>
+
+// Pkger stuff here
+```
+
+The `-o` flag can be used to specify the directory of the `pkged.go` file.
+
+```bash
+$ pkger -o cmd/reader
+```
+
+The result will be a `pkged.go` file in the **cmd/reader** folder with the embedded information and the package name of that folder.
+
+```go
+// cmd/reader/pkged.go
+package <reader>
+
+// Pkger stuff here
+```
+
+### Including Files at Package Time
+
+There may be reasons where you don't reference a particular file, or folder, that you want embedded in your application, such as a build artifact.
+
+To do this you may use either the [`github.com/markbates/pkger#Include`](https://godoc.org/github.com/markbates/pkger#Include) function to set a no-op parser directive to include the specified path.
+
+Alternatively, you may use the `-include` flag with the `pkger` and `pkger list` commands.
+
+```bash
+$ pkger list -include /actions -include github.com/gobuffalo/buffalo:/app.go
+
+app
+ > app:/actions
+ > app:/actions/actions.go
+ > app:/assets
+ > app:/assets/css

+## API Usage
 
 Pkger's API is modeled on that of the [`os`](https://godoc.org/os) package in Go's standard library. This makes Pkger usage familiar to Go developers.
 
-
+The two most important interfaces are [`github.com/markbates/pkger/pkging#Pkger`](https://godoc.org/github.com/markbates/pkger/pkging#Pkger) and [`github.com/markbates/pkger/pkging#File`](https://godoc.org/github.com/markbates/pkger/pkging#File).
 
 ```go
 type Pkger interface {
   Parse(p string) (Path, error)
-  Abs(p string) (string, error)
-  AbsPath(Path) (string, error)
   Current() (here.Info, error)

-### Output Without Packing
+## Understanding the Parser
+
+The [`github.com/markbates/pkger/parser#Parser`](https://godoc.org/github.com/markbates/pkger/parser#Parser) works by statically analyzing the source code of your module using the [`go/parser`](https://godoc.org/go/parser) to find a selection of declarations.
+
+The following declarations in your source code will tell the parser to embed files or folders.
+
+* `pkger.Dir("<path>")` - Embeds all files under the specified path.
+* `pkger.Open("<path>")` - Embeds the file, or folder, of the specified path.
+* `pkger.Stat("<path>")` - Embeds the file, or folder, of the specified path.
+* `pkger.Walk("<path>", filepath.WalkFunc)` - Embeds all files under the specified path.
+* `pkger.Include("<path>")` - `Include` is a no-op that directs the pkger tool to include the desired file or folder.
+
+### CLI Usage
+
+To see what declarations the parser has found, you can use the `pkger parse` command to get a `JSON` list of the declarations.
