   - Community
   - New Contributor's Guide
   - Advanced code contribution
   - Report bugs and propose features

   Yes, if the icons can be downloaded for free, we do not need a licence. The ones I selected are free.

       Is this needed if you included the svg files itself?

   @thisisnic no, I don't think we have a licence for Pro images but I have included only free versions and that should be fine. See https://fontawesome.com/plans under **Open Source Icons** "A solid set of icons safe for use in open source projects" near the bottom of the page.

   Yes, I would need to clarify better.
   
   For free downloadable icons it is stated that these are "A solid set of icons safe for use in open source projects." plus the paragraph you added, Joris, add the info about attribution.
   
   From this I concluded that the icons, I am able to download for free, are OK to be used.

+
+********************************
+Report bugs and propose features
+********************************
+
+Using the software and sharing your experience is a very helpful contribution
+itself. Those who actively develop Arrow need feedback from users on what
+works and what doesn't. Alerting us to unexpected behavior and missing features,
+even if you can't solve the problems yourself, help us understand and prioritize
+work to improve the libraries.
+
+We use `JIRA <https://issues.apache.org/jira/projects/ARROW/issues>`_
+to manage our development "todo" list and to maintain changelogs for releases.
+In addition, the project's `Confluence site <https://cwiki.apache.org/confluence/display/ARROW>`_
+has some useful higher-level views of the JIRA issues.
+
+To create a JIRA issue, you'll need to have an account on the ASF JIRA, which
+you can `sign yourself up for <https://issues.apache.org/jira/secure/Signup!default.jspa>`_.
+The JIRA server hosts bugs and issues for multiple Apache projects. The JIRA
+project name for Arrow is "ARROW".
+
+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs

+
+********************************
+Report bugs and propose features
+********************************
+
+Using the software and sharing your experience is a very helpful contribution
+itself. Those who actively develop Arrow need feedback from users on what
+works and what doesn't. Alerting us to unexpected behavior and missing features,
+even if you can't solve the problems yourself, help us understand and prioritize
+work to improve the libraries.
+
+We use `JIRA <https://issues.apache.org/jira/projects/ARROW/issues>`_
+to manage our development "todo" list and to maintain changelogs for releases.
+In addition, the project's `Confluence site <https://cwiki.apache.org/confluence/display/ARROW>`_
+has some useful higher-level views of the JIRA issues.
+
+To create a JIRA issue, you'll need to have an account on the ASF JIRA, which
+you can `sign yourself up for <https://issues.apache.org/jira/secure/Signup!default.jspa>`_.
+The JIRA server hosts bugs and issues for multiple Apache projects. The JIRA
+project name for Arrow is "ARROW".
+
+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs
+would get fixed as soon as they were reported. However, time and attention are
+finite, especially in an open-source project where most contributors are
+participating in their spare time. All contributors in Apache projects are
+volunteers and act as individuals, even if they are contributing to the project
+as part of their job responsibilities.
+
+In order for your bug to get prompt
+attention, there are things you can do to make it easier for contributors to
+reproduce and fix it.

+  If your bug report says "it crashes trying to read my file, but I can't
+  share it with you," it's really hard for us to debug.
+* Any relevant operating system, language, and library version information
+* If it isn't obvious, clearly state the expected behavior and what actually

   ```
   Just tidying up a bit of extra unnecessary output.

Review comment:
       It's needed for the dropdown in _contributing.rst_ - but I can just as well omit the icons (and this fix in the theme) in both dropdowns, will be fine either way.

   > @thisisnic no, I don't think we have a licence for Pro images but I have included only free versions and that should be fine. See https://fontawesome.com/plans under **Open Source Icons** "A solid set of icons safe for use in open source projects" near the bottom of the page.
   
   I'm not sure that that quote means that we can use those icons without a license, but the fact that you've only used the free ones means that it's all good anyway.  Glad we can use them as these look great!

+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs
+would get fixed as soon as they were reported. However, time and attention are
+finite, especially in an open-source project where most contributors are
+participating in their spare time. All contributors in Apache projects are
+volunteers and act as individuals, even if they are contributing to the project
+as part of their job responsibilities.
+
+In order for your bug to get prompt
+attention, there are things you can do to make it easier for contributors to
+reproduce and fix it.
+**When you're reporting a bug, please help us understand the issue by providing,
+to the best of your ability,**
+
+* **Clear, minimal steps to reproduce the issue, with as few non-Arrow
+  dependencies as possible.** If there's a problem on reading a file, try to
+  provide as small of an example file as possible, or code to create one.
+  If your bug report says "it crashes trying to read my file, but I can't
+  share it with you," it's really hard for us to debug.
+* Any relevant operating system, language, and library version information
+* If it isn't obvious, clearly state the expected behavior and what actually
+  happened.
+
+If a developer can't get a failing unit test, they won't be able to know that
+the issue has been identified, and they won't know when it has been fixed.
+Try to anticipate the questions you might be asked by someone working to
+understand the issue and provide those supporting details up front.
+
+Good reproducible examples or minimal bug reports can be found in next tabs:
+
+.. tabs::
+
+   .. tab:: Python
+
+      The ``print`` method of a timestamp with timezone errors:
+
+      .. code-block:: python
+
+         import pyarrow as pa
+
+         a = pa.array([0], pa.timestamp('s', tz='+02:00'))
+
+         print(a) # representation not correct?
+         # <pyarrow.lib.TimestampArray object at 0x7f834c7cb9a8>
+         # [
+         #  1970-01-01 00:00:00
+         # ]
+
+         print(a[0])
+         #Traceback (most recent call last):
+         #  File "<stdin>", line 1, in <module>

+         #ValueError: fromutc: dt.tzinfo is not self
+
+   .. tab:: R
+
+      Error when reading a CSV file with ``col_types`` option ``"T"`` or ``"t"``:

Review comment:
       ```suggestion

   I reckon that bug title could be even better :)

+********************************
+Report bugs and propose features
+********************************
+
+Using the software and sharing your experience is a very helpful contribution
+itself. Those who actively develop Arrow need feedback from users on what
+works and what doesn't. Alerting us to unexpected behavior and missing features,
+even if you can't solve the problems yourself, help us understand and prioritize
+work to improve the libraries.
+
+We use `JIRA <https://issues.apache.org/jira/projects/ARROW/issues>`_
+to manage our development "todo" list and to maintain changelogs for releases.
+In addition, the project's `Confluence site <https://cwiki.apache.org/confluence/display/ARROW>`_
+has some useful higher-level views of the JIRA issues.
+
+To create a JIRA issue, you'll need to have an account on the ASF JIRA, which
+you can `sign yourself up for <https://issues.apache.org/jira/secure/Signup!default.jspa>`_.
+The JIRA server hosts bugs and issues for multiple Apache projects. The JIRA
+project name for Arrow is "ARROW".
+
+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs
+would get fixed as soon as they were reported. However, time and attention are
+finite, especially in an open-source project where most contributors are
+participating in their spare time. All contributors in Apache projects are
+volunteers and act as individuals, even if they are contributing to the project
+as part of their job responsibilities.
+
+In order for your bug to get prompt
+attention, there are things you can do to make it easier for contributors to
+reproduce and fix it.
+**When you're reporting a bug, please help us understand the issue by providing,
+to the best of your ability,**
+
+* **Clear, minimal steps to reproduce the issue, with as few non-Arrow
+  dependencies as possible.** If there's a problem on reading a file, try to
+  provide as small of an example file as possible, or code to create one.
+  If your bug report says "it crashes trying to read my file, but I can't

   Trimming the extra bits of error message that wouldn't be here for users who haven't set the environment variable `ARROW_R_DEV` to `TRUE`

+********************************
+Report bugs and propose features
+********************************
+
+Using the software and sharing your experience is a very helpful contribution
+itself. Those who actively develop Arrow need feedback from users on what
+works and what doesn't. Alerting us to unexpected behavior and missing features,
+even if you can't solve the problems yourself, help us understand and prioritize
+work to improve the libraries.
+
+We use `JIRA <https://issues.apache.org/jira/projects/ARROW/issues>`_
+to manage our development "todo" list and to maintain changelogs for releases.
+In addition, the project's `Confluence site <https://cwiki.apache.org/confluence/display/ARROW>`_
+has some useful higher-level views of the JIRA issues.
+
+To create a JIRA issue, you'll need to have an account on the ASF JIRA, which
+you can `sign yourself up for <https://issues.apache.org/jira/secure/Signup!default.jspa>`_.
+The JIRA server hosts bugs and issues for multiple Apache projects. The JIRA
+project name for Arrow is "ARROW".
+
+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs
+would get fixed as soon as they were reported. However, time and attention are
+finite, especially in an open-source project where most contributors are
+participating in their spare time. All contributors in Apache projects are
+volunteers and act as individuals, even if they are contributing to the project
+as part of their job responsibilities.
+
+In order for your bug to get prompt
+attention, there are things you can do to make it easier for contributors to
+reproduce and fix it.
+**When you're reporting a bug, please help us understand the issue by providing,
+to the best of your ability,**
+
+* **Clear, minimal steps to reproduce the issue, with as few non-Arrow
+  dependencies as possible.** If there's a problem on reading a file, try to
+  provide as small of an example file as possible, or code to create one.
+  If your bug report says "it crashes trying to read my file, but I can't
+  share it with you," it's really hard for us to debug.
+* Any relevant operating system, language, and library version information
+* If it isn't obvious, clearly state the expected behavior and what actually
+  happened.
+
+If a developer can't get a failing unit test, they won't be able to know that
+the issue has been identified, and they won't know when it has been fixed.

Review comment:
       It finds `hand-point-up` but not the `pencil` icon 🤦‍♀️ 
   Looking at it I see is actually nicer without the icons in the dropdown so I will remove them.

   > Yes, if the icons can be downloaded for free, we do not need a licence.
   
   Theoretically, it's not because it is free / open source, that it might not be required to include the license if you copy some files (eg when we vendor another library in Arrow, we also include its license). 
   Now, checking the github repo, it has https://github.com/FortAwesome/Font-Awesome#license, which indicates the svg files are CC BY, which requires attribution, but there is also this paragraph:
   
   >  Downloaded Font Awesome Free files already contain embedded comments with sufficient attribution, so you shouldn't need to do anything additional when using these files normally.

+
+********************************
+Report bugs and propose features
+********************************
+
+Using the software and sharing your experience is a very helpful contribution
+itself. Those who actively develop Arrow need feedback from users on what
+works and what doesn't. Alerting us to unexpected behavior and missing features,
+even if you can't solve the problems yourself, help us understand and prioritize
+work to improve the libraries.
+
+We use `JIRA <https://issues.apache.org/jira/projects/ARROW/issues>`_
+to manage our development "todo" list and to maintain changelogs for releases.
+In addition, the project's `Confluence site <https://cwiki.apache.org/confluence/display/ARROW>`_
+has some useful higher-level views of the JIRA issues.
+
+To create a JIRA issue, you'll need to have an account on the ASF JIRA, which
+you can `sign yourself up for <https://issues.apache.org/jira/secure/Signup!default.jspa>`_.
+The JIRA server hosts bugs and issues for multiple Apache projects. The JIRA
+project name for Arrow is "ARROW".
+
+You don't need any special permissions on JIRA to be able to create issues.
+Once you are more involved in the project and want to do more on JIRA, such as
+assign yourself an issue, you will need "Contributor" permissions on the
+Apache Arrow JIRA. To get this role, ask on the mailing list for a project
+maintainer's help.
+
+
+.. _jira-tips:
+
+Tips for using JIRA
+===================
+
+Before you create a new issue, we recommend you first
+`search <https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20resolution%20%3D%20Unresolved>`_
+among existing Arrow issues.
+
+When reporting a new issue, follow these conventions to help make sure the
+right people see it:
+
+* Use the **Component** field to indicate the area of the project that your
+  issue pertains to (for example "Python" or "C++").
+* Also prefix the issue title with the component name in brackets, for example
+  ``[Python] issue name`` ; this helps when navigating lists of open issues,
+  and it also makes our changelogs more readable. Most prefixes are exactly the 
+  same as the **Component** name, with the following exceptions:
+
+  * **Component:** Continuous Integration — **Summary prefix:** [CI]
+  * **Component:** Developer Tools — **Summary prefix:** [Dev]
+  * **Component:** Documentation — **Summary prefix:** [Docs]
+
+* If you're reporting something that used to work in a previous version
+  but doesn't work in the current release, you can add the "Affects version"
+  field. For feature requests and other proposals, "Affects version" isn't
+  appropriate.
+
+Project maintainers may later tweak formatting and labels to help improve their
+visibility. They may add a "Fix version" to indicate that they're considering
+it for inclusion in the next release, though adding that tag is not a
+commitment that it will be done in the next release.
+
+.. _bug-report-tips:
+
+Tips for successful bug reports
+================================
+
+No one likes having bugs in their software, and in an ideal world, all bugs
+would get fixed as soon as they were reported. However, time and attention are
+finite, especially in an open-source project where most contributors are
+participating in their spare time. All contributors in Apache projects are
+volunteers and act as individuals, even if they are contributing to the project
+as part of their job responsibilities.
+
+In order for your bug to get prompt
+attention, there are things you can do to make it easier for contributors to
+reproduce and fix it.
+**When you're reporting a bug, please help us understand the issue by providing,
+to the best of your ability,**
+
+* **Clear, minimal steps to reproduce the issue, with as few non-Arrow
+  dependencies as possible.** If there's a problem on reading a file, try to
+  provide as small of an example file as possible, or code to create one.
+  If your bug report says "it crashes trying to read my file, but I can't
+  share it with you," it's really hard for us to debug.
+* Any relevant operating system, language, and library version information
+* If it isn't obvious, clearly state the expected behavior and what actually
+  happened.
+
+If a developer can't get a failing unit test, they won't be able to know that
+the issue has been identified, and they won't know when it has been fixed.
+Try to anticipate the questions you might be asked by someone working to
+understand the issue and provide those supporting details up front.

   @thisisnic no, I don't think we have a licence for Pro images but I have included only free versions and that should be fine. See https://fontawesome.com/plans under **Open Source Icons** "A solid set of icons safe for use in open source projects" near the bottom of the page.

Review comment:
       Ah, I see. I think it is fine to keep them. 
   In this dropdown, I suppose you cannot easily use a downloaded image as you did for the others?
   
   Now, the theme itself should normally also already include fontawesome. So I would still think that it would even work as is without the above line. For example, if you look at [view-source:https://alenkaf.github.io/arrow-dev-docs-preview/html/developers/contributing.html](view-source:https://alenkaf.github.io/arrow-dev-docs-preview/html/developers/contributing.html), there is already some other `/vendor/fontawesome/..` css included as well.
