+# How to contribute Apache Arrow Julia
+
+## Did you find a bug or have an improvement?
+
+We recommend you first search among existing [Github issues](https://github.com/apache/arrow-julia/issues). The community may already address the same idea. If you could find the issue, you may want to contribute to the existing issue.
+
+
+## How do you write a patch that fixes a bug or brings an improvement?
+If you cannot find the same idea in the issues, you first need to write a GitHub issue (e.g. [issues in Arrow-julia](https://github.com/apache/arrow-julia/issues)) for a bug fix or planned features for the improvement. To write an issue would help the community have visibility and opportunities for collaborations before a pull request (PR) shows up. This is for the [Apache way](http://theapacheway.com/). We can use GitHub labels to identify bugs.
+It should not be necessary to file an issue for some non-code changes, such as CI changes or minor documentation updates such as fixing typos.
+
+After writing the issue, you may want to write a code by creating [a PR](https://github.com/apache/arrow-julia/pulls). In the PR, it is preferable to refer to the issue number (e.g. `#1`) that you already created.
+
+
+## Do you want to propose a significant new feature or an important refactoring?
+
+We ask that all discussions about major changes in the codebase happen publicly on the [arrow-dev mailing-list](https://lists.apache.org/list.html?dev@arrow.apache.org).
+
+
+## Do you have questions about the source code, the build procedure or the development process?
+
+You can also ask on the mailing-list, see above.
+
+
+## Local Development
+
+When developing on Arrow.jl it is recommended that you run the following to ensure that any changes to ArrowTypes.jl are immediately available to Arrow.jl without requiring a release:
+
+```
+julia --project -e 'using Pkg; Pkg.develop(path="src/ArrowTypes")'
+```
+
+
+## Release cycle
+
+The Julia community would like an independent release cycle. Release for apache/arrow doesn't include the Julia implementation. The Julia implementation uses separated version scheme. (apache/arrow uses 6.0.0 as the next version but the next Julia implementation release doesn't use 6.0.0.)
