+# Create kshell terminals from a kscript
+
+
+Based on https://github.com/khud/sparklin which is a proof-of-concept software that includes experimental new Kotlin REPL.
+
+## Installation
+
+```bash
+wget https://raw.githubusercontent.com/holgerbrandl/kscript/master/misc/kshell_launcher/kshell_from_kscript.sh
+chmod +x kshell_from_kscript.sh
+```
+
+You may want to add it to your `PATH` as well.
+
+## Usage
+
+Simply provide any kscript as argument. E.g [`krangl_example.kts`]()
+```
+kshell_from_kscript.sh krangl_example.kts
+```
+
+## Todo
+
+* bundle this with kscript itself
