------------------------
+--------------------
-![Build Status](https://github.com/jscoq/jscoq/actions/workflows/ci.yml/badge.svg)
+A trimmed down version of jscoq for teaching purposes.
-jsCoq is an Online Integrated Development Environment for the
+### First time setup
-[Coq](https://coq.inria.fr) proof assistant and runs in your browser!
-We aim to enable new UI/interaction possibilities and to improve the
-accessibility of the Coq platform itself. Current stable version is
-jsCoq 0.16.1 supporting Coq 8.16.0, try it:
-<https://coq.vercel.app>
+- Install docker. Docker requires `sudo` by default, because it uses `chroot` to create a lightweight "virtual machine".
+If you are not comfortable with this, there exists an experimental [rootless version of Docker ](https://docs.docker.com/engine/security/rootless/). However, I haven't yet tested whether it works.
-jsCoq is written to conform to ES2017; any recent standard-compliant
+- In the root of the project run `sudo docker build --tag jscoq-dev-image .` this will take a while.
-browser should be able to run it. No servers or external programs are needed.
-See the [Troubleshooting](#Troubleshooting) section if you have problems.
-jsCoq is community-developed by a [team of contributors](#Credits).
-## Are you a jsCoq user?
-Have you developed or taught a course **using jsCoq**? Do you have some feedback for us?
-If so, please submit a pull request or an issue so we can add your
-lectures to the list of [jsCoq users](#jsCoq-Users). This is essential
-to guarantee future funding of the project.
-## Basic Usage
-The main page showcases jsCoq by walking through a proof for the infinitude of primes using
-[`math-comp`](https://github.com/math-comp/math-comp), due to Georges Gonthier.
-Once jsCoq finishes loading, you can step through the proof using the
-arrow buttons on the toolbar (top right), or using these keyboard
-shortcuts:
-| Shortcut           | Action           |
-|--------------------|------------------|
-| Alt-N or Alt-↓     | Go to next       |
-| Alt-P or Alt-↑     | Go to previous   |
-| Alt-Enter or Alt-→ | Go to cursor     |
-You can open a blank editor and experiment with your own Coq developments using the
-[scratchpad](https://jscoq.github.io/node_modules/jscoq/examples/scratchpad.html).
-The same keyboard shortcuts apply here.
-The scratchpad's contents are saved in your browser's local storage (IndexedDB, specifically),
-so they are not lost if you close the browser window or refresh the page.
-You can, in fact, store more than one document using the local open/save file dialogs:
-| Shortcut           | Action                                                                       |
-|--------------------|------------------------------------------------------------------------------|
-| Ctrl-S             | Save file (with the last name provided, or `untitled.v`)                     |
-| Ctrl-Shift-S       | Save file as (prompts for file name; also has options to download or share the content)  |
-| Ctrl-Alt-S         | Save file to disk (using the browser's Save dialog, or preset destination)   |
-| Ctrl-O             | Open file (prompts for file name, supports tab completion)                   |
-| Ctrl-Alt-O         | Open file from disk (using the browser's Open dialog)                        |
-On Mac, replace Ctrl with ⌘ (command) and Alt with ⌥ (option), as is traditional.
-Drag `.v` files from your local drive onto the scratchpad to open them.
-You can also drag multiple files, which will open up a project pane to the left of the editor, allowing you to switch between them; this functionality is still experimental.
-### Sharing your development
-A small pastebin-like server based on [Hastebin](https://hastebin.com) is available for sharing `.v` files between users.
-Open the save dialog (Ctrl-Shift-S) and click "Share"; then share the URL from your browser's location bar with anyone you like.
-The URL represents the state of the document at the moment it was shared, and this state is read-only. Every time you click "Share", a fresh URL is generated.
-Shared content is not saved forever, though; documents are typically available for a period of ~30 days.
-## How to build your own jsCoq documents
-See the [dedicated page](docs/embedding.md) for information on advanced
-options and jsCoq HTML embedding API. A quick setup can be done with:
+- While still in the root of the project, create a container using 
 ```
-$ npm install jscoq
+sudo docker container create -p 8000:8000 --mount type=bind,source=.,target=/root/jscoq --name jscoq-dev jscoq-dev-image
 ```
-then copy and adapt the [template page](https://github.com/ejgallego/jscoq/blob/v8.14/examples/npm-template.html)
+- You can now start the container using `sudo docker container start jscoq-dev`. This runs a web server hosting your local version of jscoq on port 8000. You can stop it using `sudo docker container stop jscoq-dev`.

-### Addon Packages
-One of jsCoq's strengths is its support for bundling addon
-packages. In order to add your Coq package to jsCoq, you need to compile
-it with jsCoq's version of Coq.
-Head over to [jscoq/addons](https://github.com/jscoq/addons) for pointers to
-some well-known packages that have been compiled for jsCoq and are bundled
-with every version of jsCoq.
-You can use these as examples for bundling your own libraries.
-## Troubleshooting
-**Are you getting a `StackOverflow` exception?** Unfortunately these
-are hard to fix; you may be stuck with them for a while.
-* Clearing the browser cache usually solves lots of issues.
-* Change browser, if using Firefox try Chrome, if using Chrome try Firefox.
-### Reporting Bugs ###
-Feel free to use the issue tracker. Please include your
-browser/OS/user-agent and any command-line options.
-### Contact and on-line help ###
- [jsCoq's Zulip Room](https://coq.zulipchat.com/#narrow/stream/256336-jsCoq), main developer chat
- [jsCoq's gitter](https://gitter.im/jscoq/Lobby), legacy developer chat
- [Coq's discourse](https://coq.discourse.group/) [use the jscoq tag], for general announcements and questions
- [StackOverflow](https://stackoverflow.com/) [use the jscoq tag]
-### What is broken ###
-* Loading ML modules is slow.
-* Loading `.vo` files is slow.
-* There surely are threading and performance problems.
-* `vm_compute` and `native_compute` fall back to regular `compute`.
-## Documents
+- After the container has been started, run `sudo docker exec -it jscoq-dev bash -c "cd /root/jscoq && ./etc/toolchain-setup.sh && make coq && make jscoq && npm link"` to compile everything for the first time
-See the `etc/notes/` directory for some random notes about the project.
+### Compiling jscoq
-## Credits
+- Make sure the container is started by running `sudo docker container start jscoq-dev`
-### Core developer team
+- Run `sudo docker exec -it jscoq-dev bash` : you are now in a shell inside the container.
- [Emilio Jesús Gallego Arias](https://www.irif.fr/~gallego/) , Inria, Université de Paris, IRIF
+- `cd /root/jscoq` to enter to the `jscoq` directory source. 
- [Shachar Itzhaky](https://cs.technion.ac.il/~shachari/) , Technion
+This is a bind mount, meaning `/root/jscoq` inside the container is actually the same directory as the git repository on your machine. You can edit the source code of jscoq outside of the container and the changes will be reflected inside the container.
-### Past Contributors
+- To compile jscoq, run `make jscoq`. The result will be saved in `_build/jscoq+32bit`. You can upload this directory to a web server; it contains an `index.html` which should work in your browser.
- Benoît Pin, [CRI, MINES ParisTech](https://www.cri.ensmp.fr)
+- You don't need to copy this directory to a web server to test your version, [the docker container runs a web server for this purpose](http://localhost:8000/_build/jscoq%2B32bit/).

+- https://news.ycombinator.com/item?id=9836900
+### Addon Packages
+One of jsCoq's strengths is its support for bundling addon
+packages. In order to add your Coq package to jsCoq, you need to compile
+it with jsCoq's version of Coq.
+Head over to [jscoq/addons](https://github.com/jscoq/addons) for pointers to
+some well-known packages that have been compiled for jsCoq and are bundled
+with every version of jsCoq.
+You can use these as examples for bundling your own libraries.
+## Troubleshooting
+**Are you getting a `StackOverflow` exception?** Unfortunately these
+are hard to fix; you may be stuck with them for a while.
+* Clearing the browser cache usually solves lots of issues.
+* Change browser, if using Firefox try Chrome, if using Chrome try Firefox.
+### Reporting Bugs ###
+Feel free to use the issue tracker. Please include your

+### What is broken ###
+* Loading ML modules is slow.
+* Loading `.vo` files is slow.
+* There surely are threading and performance problems.
+* `vm_compute` and `native_compute` fall back to regular `compute`.

+jsCoq was made possible thanks to funding by the
+[FEEVER](http://feever.fr) project and support from [MINES
+ParisTech](http://www.mines-paristech.eu)
+We want to _strongly thank_ the `js_of_ocaml` developers. Without
+their great and quick support jsCoq wouldn't have been possible.
+[CodeMirror](https://codemirror.net/) has played a crucial role in the
+project, we are very happy with it, thanks a lot!
+Please consider supporting the development of CodeMirror with a donation.
