+The algorithms are written in ES6, use `babel-node` to run them.
+
+Most algorithms have a `-debug` version which includes logs and stuff to understand the algorithm runtime better.
+
+I wanted to add tests for all algorithms but I haven't yet.

+# Contributing
+
+Contributions are always welcome, no matter how large or small. Before
+contributing, please read the
+[code of conduct](https://github.com/babel/babel/blob/master/CODE_OF_CONDUCT.md).
+
+
+## Developing
+
+#### Setup
+
+```sh
+$ git clone https://github.com/babel/babel
+$ cd babel
+$ make bootstrap
+```
+
+Then you need to run:
+
+```sh
+$ make watch-core
+```
+
+This will compile Babel and then sit in the background and on file modification
+recompile the necessary files. Babel itself is written in ES6. The source files
+reside in `src/` and transpile to `lib/`
+
+
+#### 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
+
+
