| <p>This guide is a resource for contributing to |
| Apache Arrow for new contributors.</p> |
| <p>No matter what your current skills are, you can try and make |
| your first time contribution to Arrow.</p> |
| <p>Starting to contribute to a project like Apache Arrow can be |
| intimidating. Taking small steps will make this task |
| easier.</p> |
| <section id="why-contribute-to-arrow"> |
| <h2>Why contribute to Arrow?<a class="headerlink" href="#why-contribute-to-arrow" title="Permalink to this heading">#</a></h2> |
| <p>There can be various reasons why you might want to contribute |
| to Arrow:</p> |
| <ul class="simple"> |
| <li><p>You find the project interesting and would like to try making |
| a contribution to learn more about the library and grow your skills.</p></li> |
| <li><p>You use Arrow in a project you are working on and you would like |
| to implement a new feature or fix a bug you encountered.</p></li> |
| </ul> |
| <p>Read more about the project in the <a class="reference internal" href="architectural_overview.html#architectural-overview"><span class="std std-ref">Architectural Overview</span></a> section.</p> |
| <div class="admonition note"> |
| <p class="admonition-title">Note</p> |
| <p>Contributors at Apache Arrow are following ASF’s |
| <a class="reference external" href="https://www.apache.org/foundation/policies/conduct.html">Code of Conduct</a>.</p> |

| <section id="quick-reference"> |
| <span id="quick-ref-guide"></span><h2>Quick Reference<a class="headerlink" href="#quick-reference" title="Permalink to this heading">#</a></h2> |
| <p>Here are the basic steps needed to get set up and contribute to Arrow. |
| This is meant both as a checklist and also to provide an overall picture of the process.</p> |
| <p>For complete instructions please follow <a class="reference internal" href="step_by_step/index.html#step-by-step"><span class="std std-ref">Steps in making your first PR</span></a> (a |
| step-by-step guide) or R and Python <a class="reference internal" href="tutorials/index.html#tutorial-index"><span class="std std-ref">Tutorials</span></a> for an example |
| of adding a basic feature.</p> |
| <ol class="arabic"> |
| <li><p><strong>Install and set up Git, and fork the Arrow repository</strong></p> |
| <p>See detailed instructions on how to <a class="reference internal" href="step_by_step/set_up.html#set-up"><span class="std std-ref">Set up</span></a> Git and fork the |
| Arrow repository.</p> |
| </li> |
| <li><p><strong>Build Arrow</strong></p> |
| <p>Arrow libraries include a wide range of functionalities and may require |
| the installation of third-party packages, depending on which build |
| options and components you enable. The C++ build guide |
| has suggestions for commonly encountered issues - you can find it |
| <a class="reference internal" href="../cpp/index.html#cpp-development"><span class="std std-ref">here</span></a>. |
| Anytime you are stuck, feel free to reach out via |
| appropriate <a class="reference internal" href="communication.html#communication"><span class="std std-ref">Communication</span></a> channel.</p> |
| <p>See a short description about the building process of |
| <a class="reference internal" href="step_by_step/building.html#build-arrow-guide"><span class="std std-ref">PyArrow or the R package</span></a> or go straight to detailed |
| instructions on how to build one of Arrow libraries in the |
| <a class="reference external" href="https://arrow.apache.org/docs/">documentation</a> .</p> |
| </li> |
| <li><p><strong>Run the tests</strong></p> |
| <p>We should run the tests to check if everything is working correctly. For example, |
| you can run the tests from a terminal for Python</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$ </span>pytest<span class="w"> </span>pyarrow |
| </pre></div> |
| </div> |
| <p>or in R console for R</p> |
| <div class="highlight-R notranslate"><div class="highlight"><pre><span></span><span class="n">devtools</span><span class="o">::</span><span class="nf">test</span><span class="p">()</span> |
| </pre></div> |

| <p>See also the section on <a class="reference internal" href="step_by_step/testing.html#testing"><span class="std std-ref">Testing 🧪</span></a>.</p> |
| </li> |
| <li><p><strong>Find an issue (if needed), create a new branch and work on the problem</strong></p> |
| <p><strong>Finding an issue</strong></p> |
| <p>You might already have a bug to fix in mind, or a new feature that you want to |
| implement. But if you don’t and you need an issue to work on, then you may need |
| help finding it. Read through the <a class="reference internal" href="step_by_step/finding_issues.html#finding-issues"><span class="std std-ref">Finding good first issues 🔎</span></a> section to get some ideas.</p> |
| <p><strong>Finding your way through the project</strong></p> |
| <p>The first step when starting a new project is the hardest and so we’ve |
| wrote some guides to help you with this.</p> |
| <p>You can start by reading through <a class="reference internal" href="step_by_step/arrow_codebase.html#arrow-codebase"><span class="std std-ref">Working on the Arrow codebase 🧐</span></a> section.</p> |
| <p><strong>Communication</strong></p> |
| <p>Communication is very important. You may need some help solving problems |
| you encounter on the way (this happens to developers all the time). Also, |
| if you have a GitHub issue you want to solve, then it is advisable to let the team |
| know you are working on it and may need some help.</p> |
| <p>See possible channels of <a class="reference internal" href="communication.html#communication"><span class="std std-ref">Communication</span></a>.</p> |
| </li> |
| <li><p><strong>Once you implemented the planned fix or feature, write and run tests for it</strong></p> |
| <p>See detailed instructions on how to <a class="reference internal" href="step_by_step/testing.html#testing"><span class="std std-ref">test</span></a>. Also run the linter |
| to make sure the code is <a class="reference internal" href="step_by_step/styling.html#styling"><span class="std std-ref">styled</span></a> correctly before proceeding |
| to the next step!</p> |
| </li> |
| <li><p><strong>Push the branch on your fork and create a Pull Request</strong></p> |
| <p>See detailed instructions on <a class="reference internal" href="step_by_step/pr_lifecycle.html#create-pr"><span class="std std-ref">Creating a pull request</span></a></p> |
| </li> |
| </ol> |
| <p>If you are ready you can start with building Arrow or choose to follow |
| one of the <a class="reference internal" href="tutorials/index.html#tutorial-index"><span class="std std-ref">Tutorials</span></a> on writing an R binding or Python feature.</p> |

| <h2>Different ways to contribute<a class="headerlink" href="#different-ways-to-contribute" title="Permalink to this heading">#</a></h2> |
| <p>There are lots of ways to contribute to the project besides writing code!</p> |
| <ul class="simple"> |
| <li><p>Improving the <strong>documentation</strong> is a great way to start contributing! |
| For more information visit <a class="reference internal" href="documentation.html#documentation"><span class="std std-ref">Helping with documentation</span></a> section of the guide.</p></li> |
| <li><p><strong>Apache Arrow Cookbooks</strong> are a collection of recipes for solving various problems |
| and completing different tasks using Apache Arrow. They are also a great way to start |
| contributing. For more information visit |
