 # Owl Online Tutorial
 
-The main purpose of the online tutorial is for teaching how to use Owl software. The tutorial also convers many useful numerical and system techniques in numerical computing. Furthermore, the tutorial includes in-depth discussion on the lessons learnt by building a large and complex software system to enable scientific computing in OCaml.
-
-The tooling and template reuse those in [Real World OCaml](https://realworldocaml.org/) under original authors' permission, with minor modidications.
-
-
-Test code:
-
-```ocaml
-let test_sum_reduce ?(seq = false) ?(a = true) expected shape axis =
-    let input = if seq = false then N.ones shape else N.sequential shape in
-    let output = if a = true then N.sum_reduce ~axis input else N.sum_reduce input in
-    let out_shp = N.shape output in
-    let expected = N.of_array expected out_shp in
-    close output expected
-```
-
-## Compile
-
-- `make` uses docker container to build the book.
-- `make test` synchronises with Owl API by evaluating the code snippet in the tutorial book.
-- `make compile` generates html files.
-- Edit `book/toc.scm` to add more chapters. Do not edit `book/tune` and `static/dune` directly.
-- Refer to [RWO](https://github.com/realworldocaml/book/blob/master/README.md) for details.
-
-Note that tooling is not finished at the moment. Structure and tools are copied mostly from RWO book.
-
-
-## Contribute
-
-Currently contribution to the book is mainly in the form of Pull Request. 
-Normally you only need to change one of the `README.md` files in `book/` directory, though adding inline scripts requires some special care.
-Please make sure that your local changes compile without any error, and include both the change of markdown file in `docs/` directory in a PR. 
-
-
-## Tooling
-
-The following tools are used in the project, please refer to their documentation.
-
-- [Pandoc](https://pandoc.org/MANUAL.html)
-- [Pandoc-crossref](http://lierdakil.github.io/pandoc-crossref/)
