+# IpynbDiff: Better diff for Jupyter Notebooks
+
+This is a simple diff tool that cleans up Jupyter notebooks, transforming each [notebook](example/1/from.ipynb)
+into a [readable markdown file](example/1/from_html.md), keeping the output of cells, and running the
+diff after. Markdowns are generated using an opinionated Jupyter to Markdown conversion. This means
+that the entire file is readable on the diff.
+
+The result are diffs that are much easier to read:
+
+| Diff                                | IpynbDiff                                             |
+| ----------------------------------- | ----------------------------------------------------- |
+| [Diff text](example/diff.txt)       | [IpynbDiff text](example/ipynbdiff_percent.txt)       |
+| ![Diff image](example/img/diff.png) | ![IpynbDiff image](example/img/ipynbdiff_percent.png) |
+
+This started as a port of [ipynbdiff](https://gitlab.com/gitlab-org/incubation-engineering/mlops/poc/ipynbdiff),
+but now has extended functionality although not working as git driver.
+
+## Usage
+
+### Generating diffs
+
+```ruby
+IpynbDiff.diff(from_path, to_path, options)
+```
+
+Options:
+
+```ruby
+@default_transform_options = {
+  preprocess_input: true, # Whether the input should be transformed
+  write_output_to: nil, # Pass a path to save the output to a file
+  format: :text, # These are the formats Diffy accepts https://github.com/samg/diffy
+  sources_are_files: false, # Weather to use the from/to as string or path to a file
+  raise_if_invalid_notebook: false, # Raises an error if the notebooks are invalid, otherwise returns nil
+  transform_options: @default_transform_options, # See below for transform options
+  diff_opts: {
+    include_diff_info: false # These are passed to Diffy https://github.com/samg/diffy
+  }
+}
+```
+
+### Transforming the notebooks
+
+It might be necessary to have the transformed files in addition to the diff.
+
+```ruby
+IpynbDiff.transform(notebook, options)
+```
+
+Options:
+
+```ruby
+@default_transform_options = {
+    include_frontmatter: false, # Whether to include or not the notebook metadata (kernel, language, etc)
+}
+```
