 # EnvKey for .net Framework
 
-[NuGet Package](https://www.nuget.org/packages/EnvKey)  
-[EnvKey Releases](https://github.com/envkey/envkey-fetch/releases)
+Integrate [EnvKey](https://www.envkey.com) with your .net projects to keep api keys, credentials, and other configuration securely and automatically in sync for developers and servers.
 
-The current envkey nuget package supports only windows on x64.
-If you wish to use it on linux or mac please [open an issue](https://github.com/envkey/envkey-dotnet/issues) to show your demand.
+## Installation
 
-# Usage
+envkey-dotnet is distributed as a [NuGet Package](https://www.nuget.org/packages/EnvKey). Please refer to the [NuGet Documentation](https://docs.microsoft.com/en-us/nuget/consume-packages/overview-and-workflow) for instructions on installing a package through the Visual Studio Package Manager UI or the command line.
+
+## Usage
+
+First, generate an `ENVKEY` in the [EnvKey App](https://github.com/envkey/envkey-app). Then set `ENVKEY=...`, either in a gitignored `.env` file in the root of your project (in development) or in an environment variable (on servers).
+
+Next, initialize the envkey package at the start of your project's `Main` method.
 
 ```cs
 var envKey = new EnvKeyConfig();
 var success = envKey.Load();
+```
+
+Now you can access your EnvKey config anywhere you need it using `Environment.GetEnvironmentVariable` and these values will always be up-to-date.
 
+```cs
 Stripe.ApiKey = Environment.GetEnvironmentVariable("STRIPE_SECRET_KEY");
 ```
 
-## Building
+### Errors
+
+The package will throw an error if an `ENVKEY` is missing or invalid.
+
+### Overriding Vars
+
+This package will not overwrite existing environment variables or additional variables set in a `.env` file. This can be convenient for customizing environments that otherwise share the same configuration. You can also use [sub-environments](https://blog.envkey.com/development-staging-production-and-beyond-85f26f65edd6) in the EnvKey app for this purpose.
+
+### Working Offline
+
+This package caches your encrypted config when in `DEBUG` mode so that you can still use it while offline. Your config will still be available (though possibly not up-to-date) the next time you lose your internet connection. If you do have a connection available, envkey-dotnet will always load the latest config. Your cached encrypted config is stored in `$HOME/.envkey/cache`
+
+## envkey-fetch binaries
+
+If you look at the `NuGet/download_envkey.bat` script, you'll find that a number of `envkey-fetch` binaries for various platforms are pulled into the package before release. These are output by the [envkey-fetch Go library](https://github.com/envkey/envkey-fetch). It contains EnvKey's core cross-platform fetching, decryption, verification, web of trust, redundancy, and caching logic. It is completely open source.

 ### Preface
 
 Versions of envkey should go hand in hand with the nuget package version to keep things tidy.  
-That means that a envkey version 1.2.0 should be downlaoded (via `download_envkey.bat`) and a package should be generated with version 1.2.0 (via `build.bat` and `pack.bat`).  
-To release library changes that refer to a certain version of envkey, the package should get a build-version extension, eg. 1.2.0.**3**.
+That means that a envkey version 1.2.4 should be downloaded (via `download_envkey.bat`) and a package should be generated with version 1.2.4 (via `build.bat` and `pack.bat`).  
+To release library changes that refer to a certain version of envkey, the package should get a build-version extension, eg. 1.2.4.**3**.
