+## Building
+
+You need [Ragel](http://www.colm.net/open-source/ragel/) and a C compiler.
+
+Ragel is used to generate `shortcodes.c` out of `shortcodes.rl`.
+As a convenience there is a generated `shortcodes.c` in the repo,
+
+Then:
+
+```shell
+  cd src && make
+```
+
+To run tests:
+
+```shell
+  crystal spec
+```
+
+## Installation
+
+1. Add the dependency to your `shard.yml`:
+
+   ```yaml
+   dependencies:
+     cr-discount:
+       github: ralsina/shortcodes
+   ```
+
+2. Run `shards install`
+
+## Usage
+
+```crystal
+require "shortcodes"
+```
