+# stack-templatizer
+
+Stack Templatizer is a small application that lets you generate stack template
+`hsfiles` from a folder.
+
+Install or clone & build the project using `stack`:
+
+```
+# Install from Stack Nightly
+stack install stack-templatizer --nightly
+
+# Or build and install from source
+git clone https://github.com/prikhi/stack-templatizer
+cd stack-templatizer
+stack install
+```
+
+Once installed, you can run `stack-templatizer my-template-folder` to generate
+a `my-template-folder.hsfiles` stack template.
