+# SPoNgEBoB
+[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bgithub.com%2Fcalini%2Fspongebob.svg?type=shield)](https://app.fossa.io/projects/git%2Bgithub.com%2Fcalini%2Fspongebob?ref=badge_shield)
+
+Simple project for converting normal text to sPonGeBOb tExT
+
+It uses _CUTTING EDGE™_ technology like *MARKOV CHAINS* to generate REALISTICⓇ SPonGeBoB text.️
+
+## Getting it
+```sh
+go get -u github.com/calini/spongebob
+```
+
+## Using the CLI
+
+```sh
+spongebob "hello world"
+> hELlO wOrlD
+```
+
+## Building it manually
+```sh
+go build -o ./spongebob
+
+./spongebob "hello world"
+> hELlO wOrlD
+```
+
+## Using it as a library
+```go
+package main
+
+import (
+	"fmt"	
+
+	"github.com/calini/spongebob"
+)
+
+func main() {
+    fmt.Println(spongebob.Text("Hello world!"))
+}
+```
