 Command-line tool to encode and decode arbitrary protobuf data.
 
-
-## Installation
-
-This program requires Crystal. See: https://crystal-lang.org/install/
-
-### Standalone
-
-1. Clone: `git clone https://github.com/iv-org/protodec && cd protodec`
-2. Build: `crystal build src/protodec.cr`
-3. See [Usage](#Usage) below
-
-
-### As a Crystal library
-
-Add this to your application's `shard.yml`:
-
-```yaml
-dependencies:
-  protodec:
-    github: iv-org/protodec
-    version: ~> 0.1.5
-```

-## Windows
-
-Windows users can run the binaries in a linux-on-windows tool (like Git bash or WSL) or use the official [protobuf binaries](https://github.com/protocolbuffers/protobuf/releases) to encode/decode protobuf data.
