 ## Developing
 
-> Note: Babel moves fast. Only the latest release is guaranteed to build correctly.
-> Older releases are not officially supported. If you attempt to build them, do that at your own risk.
-
 #### Setup
 
-```sh
-$ git clone https://github.com/babel/babel
-$ cd babel
-$ make bootstrap
-```
-
-Then you can either run:
-
-```sh
-$ make build-core
-```
-
-to build Babel **once** or:
-
-```sh
-$ make watch-core
-```
-
-to have Babel build itself then incrementally build files on change.
-
-#### Running tests
-
-You can run tests via:
-
-```sh
-$ make test
-```
-
-This is mostly overkill and you can limit the tests to a select few by directly
-running them with `mocha`:
-
-```sh
-$ mocha test/core/transformation.js
-```
-
-Use mocha's `--grep` option to run a subset of tests by name:
-
-```sh
-$ mocha test/core/transformation.js --grep es7
-```
-
-If you don't have `mocha` installed globally, you can still use it from Babel's
-dependencies in `node_modules`, but make sure `node_modules/.bin` is added to
-your [`$PATH`](http://unix.stackexchange.com/questions/26047/how-to-correctly-add-a-path-to-path) environment variable.
-
-
-#### Workflow
-
-* Fork the repository
-* Clone your fork and change directory to it (`git clone git@github.com:yourUserName/babel.git && cd babel`)
-* Install the project dependencies (`make bootstrap`)
-* Link your forked clone (`npm link`)
-* Develop your changes ensuring you're fetching updates from upstream often
-* Ensure the test are passing (`make test`)
-* Create new pull request explaining your proposed change or reference an issue in your commit message
-
-#### Dependencies
-
-+ [ast-types](http://ghub.io/ast-types) This is required to monkeypatch regenerators AST definitions. Could be improved in the future.
-
-+ [chalk](http://ghub.io/chalk) This is used for terminal color highlighting for syntax errors.
-
-+ [convert-source-map](http://ghub.io/convert-source-map) Turns a source map object into a comment etc.
-
-+ [core-js](http://ghub.io/core-js) Used for the polyfill.
-
-+ [debug](http://ghub.io/debug) Used to output debugging information when NODE_DEBUG is set to babel.
-
-+ [detect-indent](http://ghub.io/detect-indent) This is used in the code generator so it can infer indentation.
-
-+ [estraverse](http://ghub.io/estraverse) The only method on this is attachComments. I'd like to implement our own comment attachment algorithm eventually though.
-
-+ [esutils](http://ghub.io/esutils) Various ES related utilities. Check whether something is a keyword etc.
-
-+ [fs-readdir-recursive](http://ghub.io/fs-readdir-recursive) Recursively search a directory for.
-
-+ [globals](http://ghub.io/globals) A list of JavaScript global variables. This is used by the scope tracking to check for colliding variables.
-
-+ [is-integer](http://ghub.io/is-integer) Checks if something is an integer.
-
-+ [js-tokens](http://ghub.io/js-tokens) This is used to get tokens for syntax error highlighting.
-
-+ [line-numbers](http://ghub.io/line-numbers) Used to produce the code frames in syntax errors.
-
-+ [lodash](http://ghub.io/lodash) Used for various utilities.
-
-+ [minimatch](http://ghub.io/minimatch) This is used to match glob-style ignore/only filters.
-
-+ [output-file-sync](http://ghub.io/output-file-sync) Synchronously writes a file and create its ancestor directories if needed.
-
-+ [path-is-absolute](http://ghub.io/path-is-absolute) Checks if a path is absolute. C:\foo and \foo are considered absolute.
-
-+ [regenerator](http://ghub.io/regenerator) This is used to transform generators/async functions.
-
-+ [regexpu](http://ghub.io/regexpu) Used to transform unicode regex patterns.
-
-+ [repeating](http://ghub.io/repeating) Repeats a string.
-
-+ [shebang-regex](http://ghub.io/shebang-regex) Literally just a regex that matches shebangs.
-
-+ [slash](http://ghub.io/slash) Normalises path separators.
-
-+ [source-map](http://ghub.io/source-map) Generates sourcemaps.
-
-+ [source-map-support](http://ghub.io/source-map-support) Adds source map support to babel-node/babel/register.
-
-+ [strip-json-comments](http://ghub.io/strip-json-comments) Remove comments from a JSON string. This is used for .babelrc files.
-
-+ [to-fast-properties](http://ghub.io/to-fast-properties) A V8 trick to put an object into fast properties mode.
-
-+ [trim-right](http://ghub.io/trim-right) Trims the rightside whitespace.
-
-+ [path-exists](https://www.npmjs.com/package/path-exists) Checks if a path exists. (replaces the deprecated `fs.exists` methods)
-
-+ [home-or-tmp](https://github.com/sindresorhus/home-or-tmp) Gets the user home directory with fallback to the system temporary directory. This is used to resolve the babel-node/babel/register cache.
-
-+ [resolve](https://www.npmjs.com/package/resolve) Implements the [`require.resolve()` algorithm](http://nodejs.org/docs/v0.12.0/api/all.html#all_require_resolve) such that we can `require.resolve()` on behalf of a file asynchronously and synchronously.
