-Sync a directory with Nomad Variables
+Nomad Var DirSync is a command-line tool designed to synchronize directories with Nomad variables. It allows you to write the contents of a directory to Nomad variables and read Nomad variables back into a directory.
+
+## Installation
+
+To install Nomad Var DirSync, you need to have Go installed on your machine. You can download and install Go from [the official website](https://golang.org/dl/).
+
+Once you have Go installed, you can install Nomad Var DirSync by running the following command:
+
+```sh
+go install git.iamthefij.com/iamthefij/nomad-var-dirsync@latest
+```
+
+## Usage
+
+Nomad Var DirSync provides two main actions: `write` and `read`.
+
+### Write Directory to Nomad Variables
+
+To write the contents of a directory to Nomad variables, use the `write` action:
+
+```sh
+nomad-var-dirsync -root-var=<root-variable-path> write <source-directory>
+```
+
+- `-root-var`: The root path for the Nomad variable.
+- `<destination-directory>`: The path to the directory you want to write to Nomad variables.
+
+### Read Nomad Variables to Directory
+
+To read Nomad variables back into a directory, use the `read` action:
+
+```sh
+nomad-var-dirsync -root-var=<root-variable-path> -dir-perms=<permissions> read <target-directory>
+```
+
+- `-root-var`: The root path for the Nomad variable.
+- `-dir-perms`: (Optional) Default permissions for new directories (default: `0o777`).
+- `<target-directory>`: The path to the directory where you want to read the Nomad variables.
+
+
+## Environment Variables
+
+- `NOMAD_ADDR`: The address of the Nomad server (default: `http://localhost:4646`).
+- `NOMAD_TOKEN`: The secret ID token for authenticating with the Nomad API.
+
+This should also support the same environment variables as the official [Nomad CLI](https://www.nomadproject.io/docs/commands/cli).
