You can download prebuilt packages from <http://paperjs.org/download/>.
As of July 2013, the recommended way to install and maintain Paper.js is through Bower for browsers, and through NPM for Node.js.
The recommended way to install and maintain Paper.js as a dependency in your
project is through Bower for browsers, and through NPM for Node.js.
For OSX see <http://madebyhoundstooth.com/blog/install-node-with-homebrew-on-os-x/> for a tutorial explaining how to install Node.js, NPM and Bower.
For Linux see <http://nodejs.org/download/> to locate 32-bit and 64-bit nodejs binaries as well as sources. It is recommended that you download directly from the nodejs site; the version available via many OS-supplied package managers is out-of-date and doesn't work with many of the packages paper uses. NPM is now included with the nodejs distribution. Once nodejs (with npm) has been installed you can install bower using the following command:
npm install -g bower
With Bower installed, simply type this command in your project folder:
If Bower is already installed installed, simply type this command in your
project folder:
bower install paper
Upon execution, you will find a `paper` folder inside the project's `bower_components` folder. For more information on Bower and to learn about its features for dependence tracking, see <http://bower.io/>.

`bower_components` folder.
## Which Version to Use?
For more information on how to install Bower, read the chapter [Installing
Node.js, NPM and Bower](#installing-nodejs-npm-and-bower).
The various distributions come with three different pre-build versions of Paper.js, in minified and normal variants:
To learn more about its features for dependence tracking, see
<http://bower.io/>.
- `paper-full.js` – The full version for the browser, including PaperScript support and Acorn.js
- `paper-core.js` – The core version for the browser, without PaperScript support nor Acorn.js. Use this to shave off some bytes when working with JavaScript directly.
- `paper-node.js` – The version for Node.js. It is recommended to install this through NPM, see below.

The easiest way to install Cairo is install Homebrew <http://mxcl.github.io/homebrew/> then issue the command:
Node.js is required by Bower, as well as by Gulp, which needs to be installed if
you intend to build the library or its documentation by yourself.
There are many tutorials explaining the different ways to install Node.js on
different platforms. It is generally not recommended to install Node.js through
OS-supplied package managers, as the its development cycles move fast and these
versions are often out-of-date.
NVM can be used instead to install and maintain multiple versions of Node.js on
the same platform, as often required by different projects:
<http://blog.dynamicprogrammer.com/2014/02/18/installing-node-js-on-mac-osx.html>
on OSX, [Homebrew](http://brew.sh/) is also a good option if one version of
Node.js on the platform is enough:
<http://blog.teamtreehouse.com/install-node-js-npm-mac>
Homebrew is recommended on OSX also if you intend to install Paper.js for
Node.js, as described in the next paragraph.
For Linux see <http://nodejs.org/download/> to locate 32-bit and 64-bit nodejs
binaries as well as sources, or use NVM: <http://learn.bevry.me/node/install/>
Once Node.js (with NPM) has been installed you can install bower *globally*
using the following command:
npm install -g bower
And from there onwards, you should be able to use Bower like this:
bower search paperjs

**Get the source (for building):**
The main Paper.js source tree is hosted on
[GitHub](https://github.com/paperjs/paper.js/). `git` is required to create a
clone of the repository, and can be easily installed through your preferred
package manager on your platform.
### Get the Source
git clone --recursive git://github.com/paperjs/paper.js.git
**Get the source (for contributing):**
If you want to contribute to the project you will have to [make a fork](http://help.github.com/forking/). Then do this:
git clone --recursive git@github.com:yourusername/paper.js.git
cd paper.js
git remote add upstream git://github.com/paperjs/paper.js.git
### Refreshing Your Clone
To fetch changes from origin (your fork), run
To refresh your clone and fetch changes from origin, run:
git fetch origin

### Setting Up For Building
Paper.js has a couple of dependencies as Bower and NPM modules. See <http://madebyhoundstooth.com/blog/install-node-with-homebrew-on-os-x/> for a tutorial explaining how to install Node.js, NPM and Bower on OSX.
As of 2016, Paper.js uses [Gulp](http://gulpjs.com/) for building, and has a
couple of dependencies as Bower and NPM modules. Read the chapter [Installing
Node.js, NPM and Bower](#installing-nodejs-npm-and-bower) if you still need to
install these.
In order to be able to build Paper.js, after checking out the repository, paper has dependencies that need to be installed. Install them by issuing the following commands from the paper.js directory:
In order to be able to build Paper.js, after checking out the repository, paper
has dependencies that need to be installed. Install them by issuing the
following commands from the Paper.js directory:
npm install
bower install
You might find that the npm command fails attempting to fetch packages needed for dependencies due to using https (the default protocol to access the npm registry). If that is the case you can switch to using http for registry access with the following command:
It is also recommended to install Gulp globally, so you can easier execute the
build commands from anywhere in the command line:
npm config set registry http://registry.npmjs.org/
Next you need to create minified versions of some of these dependencies. This is handled by the `minify-components.sh` script inside the `build` folder:
cd build
./minify-components.sh
npm install -g gulp
### Building the Library
The Paper.js sources are distributed across many separate files, organised in subfolders inside the `src` folder. To compile them all into one distributable file, you can run the `build.sh` script inside the `build` folder:
The Paper.js sources are distributed across many separate files, organised in
subfolders inside the `src` folder. To compile them all into distributable
files, you can run the `build` task:
cd build
./build.sh
gulp build
You will then find the built library inside the `dist` folder, named `paper.js`.
`build.sh` offer two modes:
commented Preprocessed but still formated and commented
stripped Formated but without comments (default)
In order to minify the resulting built versions, you can run the `minify.sh` script:
cd build
./minify.sh
You will then find the built library files inside the `dist` folder, named
`paper-full.js`, `paper-core.js` and `paper-node.js`, along with their minified
versions. Read [Which Version to Use?](#which-version-to-use) for an explanation
of the different versions.
### Running Directly from Separate Source Files
As a handy alternative to building the library after each change to try it out in your scripts, there is a helper script `src/load.js` that loads the library directly from all the separate source files in the `src` folder. The shell script `load.sh` in the `build` folder produces the `paper-full.js` and `paper-node.js` files in `dist` as symbolic links to `src/load.js`. This means you can switch between loading from sources and loading a built library simply by running `build.sh` or `load.sh` inside the `build` folder.
As a handy alternative to building the library after each change to try it out
in your scripts, there is the helper task `load`, that replaces the built
libraries with symbolic links to the `scrc/load.js` script. This script then
load the library directly from all the separate source files in the `src`
folder, through the [Prepro.js](https://github.com/lehni/prepro.js) JavaScript
preprocessing library.
cd build
./load.sh
This means you can switch between loading from sources and loading a built
library simply by running.
gulp load
And to go back to a built library
cd build
./build.sh
gulp build
Note that your PaperScripts examples do not need to change, they can keep loading `dist/paper-full.js`, which will always do the right thing. Note also that `src/load.js` handles both browsers and Node.js, through the handy Prepro.js preprocessing library <http://github.com/lehni/prepro.js>.

loading `dist/paper-full.js`, which will always do the right thing. Note also
that `src/load.js` handles both browsers and Node.js, as supported by Prepro.js.
### Other Build Tasks
Create a final zipped distribution file inside the `dist` folder:
gulp dist
And since `dist` is the default task, this is the same:
gulp
### Branch structure
Since the release of version `v0.9.22`, Paper.js has adopted aspects of the Git-Flow workflow. For now, this just means that all development is taking place in the `develop` branch, which is only merged into `master` when a new release occurs. On this `develop` branch, `src/load.js` is used by default to load the library.

### Testing
Paper.js was developed and tested from day 1 using proper unit testing through jQuery's [Qunit](http://docs.jquery.com/Qunit). To run the tests after any change to the library's source, simply open `index.html` inside the `test` folder in your web browser. There should be a green bar at the top, meaning all tests have passed. If the bar is red, some tests have not passed. These will be highlighted and become visible when scrolling down.

**Use one topic branch per feature** -- don't mix different kinds of patches in the same branch. Instead, merge them all together into your `develop` branch (or develop everything in your `develop` branch and then cherry-pick-and-merge into the different topic branches). Git provides for an extremely flexible workflow, which in many ways causes more confusion than it helps you when new to collaborative software development. The guides provided by GitHub at <http://help.github.com/> are a really good starting point and reference.
If you are fixing an issue, a convenient way to name the branch is to use the issue number as a prefix, like this: `git checkout -tb 53-feature-manually-select-language`.
