-# Corso documentation
-
-Corso documentation uses [Docusaurus 2](https://docusaurus.io/), a modern static website generator.
-[Mermaid](https://mermaid-js.github.io/mermaid/) provides support for native diagrams in Markdown.
-
-## Requirements
-
-Developing documentation for Corso requires the following tools on your machine:
-
-- `make`
-- Docker
-
-## Installation
-
-```bash
-make buildimage
-```
-
-## Live documentation development
-
-```bash
-make dev
-```
-
-This command starts a local development server within the Docker container and will expose docs at [http://localhost:3000](http://localhost:3000).
-
-## Generating Corso CLI docs
-
-```bash
-make genclidocs
-```
-
-Corso's CLI documents are auto generated. This command explicitly triggers generating these docs. This step will happen
-automatically for the other commands where this is relevant.
-
-## Building static documentation
-
-```bash
-make build
-```
-
-This command generates static content into the `build` directory for integration with any static contents hosting service.
-
-## Serving static documentation
-
-```bash
-make serve
-```
-
-This command will serve the static content generated with `make build` at [http://localhost:3000](http://localhost:3000).
-
-## Style and linting
-
-```bash
-# Lint all docs
-make check
-# Lint specific files and/or folders
-make check VALE_TARGET="README.md docs/concepts"
-```
-
-This command will lint all Markdown files and check them for style issues using the Docker container
-
-## Documentation platform development
-
-```bash
-make shell
-```
-
-Use this command to interactively (and temporarily!) change the contents or
-configuration of the live documentation container image (for example, when
-experimenting with new plugins).
