+Config Catalyst automatically converts static config files in your repos into parameterized templates.
+It's the easiest way to "pay down config tech debt" with a single command.
+We :heart: feedback, [bugs](https://github.com/cloudtruth/config-catalyst/issues/new), and [enhancement suggestions](https://github.com/cloudtruth/config-catalyst/issues/new). We also have a #config-catalyst channel [on our Discord](https://discord.com/invite/eBZXm9Tzr7).
+
+# Motivation
+Config Catalyst exists to solve this problem:
+"I need to take this weird network config that Bob (who left five years ago) roughed out by hand and turn it into a crisp little YAML template with parameterized variables."
+Static, hard-coded config is a form of "tech debt" many teams want to eliminate, but the "pay it down" process is tedious and time consuming.
+
+# How it works
+Config Catalyst works off of a local copy of your repo folder structure.
+1. Scans your repos and finds all the configuration files (JSON, YAML, ENV, HCL, TF_Var, etc..)
+1. Automatically creates parameterized templates with linked parameters and secrets to the parameter/secret store.
+1. Result: Finally, parameter and secret changes can be reflected in all the config files that use/depend on them.
+
+You don't need to build all the plumbing anymore. Config file changes are independent of param/secret variable changes.
 
-# Supported file types
+Need to manage values across multiple environments with one template? No problem!
+
+Bonus: Optionally, the variables and secrets can be synced to Azure Key Vault, AWS Secrets Manager, ParameterStore, or Vault.
+
+# Features and supported file types
+
+**Current file type support includes**:
 * JSON
 * YAML
 * dotenv
 * tfvars
 * variables.tf
 
-## Not yet supported (but planned)

-# Usage
+# Installation
 This utility is distributed as a Docker container and can be pulled from cloudtruth/config-catalyst on Docker Hub
 
+Clone your repo(s) to local disk to allow Config Catalyst to find the supported file types.
+
+You will need a CloudTruth [API token](https://app.cloudtruth.io/organization/api) to complete the process.
+
+Use your existing account or create a free [CloudTruth account](https://app.cloudtruth.io/signup) to get an API token.
+
+# Usage
+
 ## Procesing a directory tree (the easy method)
 You can feed a directory of files into the `walk-directories` command, which will find all files matching the supplied types and parse them into CloudTruth config formats. If you supply your CLOUDTRUTH_API_KEY via docker, the data will be uploaded to your CloudTruth account.
 
 ```
 docker run --rm -it -e CLOUDTRUTH_API_KEY="myverysecureS3CR3T!!" -v ${PWD}/files:/app/files cloudtruth/config-catalyst walk-directories --config-dirs /app/samples/ -t dotenv -t json -t tf
 ```
 
-# Advanced Usage
 ## Processing a single file

+An example of how to process a .env file. This example assumes you have one .env file in the current directory that will be mounted through to the container
+
 ```
-docker run --rm -v ${PWD}/files:/app/files cloudtruth/config-catalyst process-configs -p myproj --default-values /app/samples/.env.sample --file-type dotenv --output-dir /app/files/
+docker run --rm -v ${PWD}:/app/files cloudtruth/config-catalyst walk-directories --config-dirs /app/files/ --file-type dotenv --output-dir /app/files/
 ```
 
-This command will mount a subdir `files` from the current working directory to the container. Assuming your input file is in that dir, the processed files will be placed in that dir once processing has completed.
+# Advanced Usage
+These examples break down the directory walking method into its individual components.

 See `dynamic_importer.processors` and the subclasses within for examples of the current design. TL;DR - if you can convert the source into a dict, `BaseProcessor._traverse_data` should handle most of the heavy lifting.
 
-# Counter-examples
-Because this has come up internally, this utility is intended to process config data, not application code or even raw IaC code. If you want to feed it a full Terraform manifest, you're going to get strange results. Pull your common variables into a variables.tf first!
