-# Build this project
-
-## Preparation
-
-1. Install [Node.js](https://nodejs.org/en/).
-2. Go to the project root, run `npm install`. This will install all required dependencies.
-
-Extra preparations are needed if you want to pull locale files from Transifex:
-
-1. Install Transifex client. Follow the instructions on [this page](https://docs.transifex.com/client/installing-the-client).
-2. You need a `.transifexrc` file in the root folder. Contact another admin if you need one. It includes the API key to use Transifex's API.
-
-## Generate the ZIP release
-
-Use the following command to generate a ZIP file that can be submitted to AMO or CWS:
-
-```
-npm run zip
-```
-
-The zip file includes all the files from the repository **except**:
-
-* All dot files (e.g. `.eslintrc` & `.gitignore`).
-* `node_modules` folder.
-* `tools` folder.
-* `package.json` file.
-* `package-lock.json` and/or `yarn.lock` file(s).
-
-<!-- FIXME: is this statement still true?
-* `vendor/codemirror/lib` files. This path is excluded because it contains a file modified for development purposes only. Instead, the CodeMirror files are copied directly from `node_modules/codemirror/lib`.
--->
-
-## Tag a release/Bump the version
-
-Use the `npm version (major | minor | patch)` command to tag a release.
-
-There are some scripts that will run automatically before/after tagging a version. Includes:
-
-1. Test.
-2. Update version number in `manifest.json`.
-3. Generate the ZIP file.
-4. Push the tag to github.
-
-## Translation
-
-We host locale files (`message.json`) on Transifex. All the files exist in our GitHub repository, but if you need to update the locale files, you will need to install the [Transifex client](https://docs.transifex.com/client/installing-the-client)
-
-To pull files from Transifex, run
-
-```
-npm run update-locales
-```
-
-To push files to Transifex:
-
-```
-npm run update-transifex
-```
-
-## 3rd-party libraries
-
-3rd-party libraries are managed by `npm`. Since Stylus is built with vanilla JS, we only use libraries that can run in the browser.
-
-We keep a copy of these libraries inside the `vendor` directory so users can side-load this repository without executing the build script. These files are downloaded from CDN or pulled from npm (`node_modules`).
-
-To add/update a library to the latest version, run `npm install PACKAGE_NAME@latest`.
-
-To remove a library, run `npm uninstall PACKAGE_NAME`.
-
-After the (un)installation, specify files which should be copied in `tools/build-vendor.js` and run `npm run build-vendor` to rebuild the vendor folder.
