+# Contributing to reneeTools
+
+## Proposing changes with issues
+
+If you want to make a change, it's a good idea to first
+[open an issue](https://code-review.tidyverse.org/issues/)
+and make sure someone from the team agrees that it’s needed.
+
+If you've decided to work on an issue,
+[assign yourself to the issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/assigning-issues-and-pull-requests-to-other-github-users#assigning-an-individual-issue-or-pull-request)
+so others will know you're working on it.
+
+## Pull request process
+
+We use [GitHub Flow](https://docs.github.com/en/get-started/using-github/github-flow)
+as our collaboration process.
+Follow the steps below for detailed instructions on contributing changes to
+reneeTools.
+
+![GitHub Flow diagram](./img/GitHub-Flow_bg-white.png)
+
+### Clone the repo
+
+If you are a member of [CCBR](https://github.com/CCBR),
+you can clone this repository to your computer or development environment.
+Otherwise, you will first need to
+[fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo)
+the repo and clone your fork. You only need to do this step once.
+
+```sh
+git clone https://github.com/CCBR/reneeTools
+```
+
+> Cloning into 'reneeTools'...
+> remote: Enumerating objects: 1136, done.
+> remote: Counting objects: 100% (463/463), done.
+> remote: Compressing objects: 100% (357/357), done.
+> remote: Total 1136 (delta 149), reused 332 (delta 103), pack-reused 673
+> Receiving objects: 100% (1136/1136), 11.01 MiB | 9.76 MiB/s, done.
+> Resolving deltas: 100% (530/530), done.
+
+```sh
+cd reneeTools
+```
+
+### If this is your first time cloning the repo, install dependencies
+
+- In an R console, install the R development dependencies with
+ `devtools::install_dev_deps()`, and then make sure the package passes R CMD
+ check by running `devtools::check()`. If R CMD check doesn't pass cleanly,
+ it's a good idea to ask for help before continuing.
+
+- Install [`pre-commit`](https://pre-commit.com/#install) if you don't already
+ have it. Then from the repo's root directory, run
+
+ ```sh
+ pre-commit install
+ ```
+
+ This will install the repo's pre-commit hooks.
+ You'll only need to do this step the first time you clone the repo.
+
+### Create a branch
+
+ Create a Git branch for your pull request (PR). Give the branch a descriptive
+ name for the changes you will make, such as `iss-10` if it is for a specific
+ issue.
+
+ ```sh
+ # create a new branch and switch to it
+ git branch iss-10
+ git switch iss-10
+ ```
+
+ > Switched to a new branch 'iss-10'
+
+### Make your changes
+
+Edit the code, write unit tests, and update the documentation as needed.
+
+#### style
+
+New code should follow the tidyverse [style guide](https://style.tidyverse.org).
+You can use the [styler](https://CRAN.R-project.org/package=styler) package to
+apply these styles, but please don't restyle code that has nothing to do with
+your PR.
+
+#### test
+
+Most changes to the code will also need unit tests to demonstrate that the
+changes work as intended.
+Use [`testthat`](https://testthat.r-lib.org/) to create your unit tests and test
+the code.
+Test files are organized as described in
+.
+Take a look at the existing code in this package for examples.
+
+#### document
+
+If you have written a new function or changed the API of an existing function,
+you will need to update the function's documentation using
+[roxygen2](https://cran.r-project.org/package=roxygen2) with
+[Markdown syntax](https://roxygen2.r-lib.org/articles/rd-formatting.html).
+See instructions on writing roxygen2 comments here:
+.
+If the function is used in a vignette, you may also need to update the vignette.
+
+#### check
+
+After making your changes, run `devtools::check()` from an R console to make
+sure the package still passes R CMD check.
+
+### Commit and push your changes
+
+If you're not sure how often you should commit or what your commits should
+consist of, we recommend following the "atomic commits" principle where each
+commit contains one new feature, fix, or task.
+Learn more about atomic commits here:
+
+
+First, add the files that you changed to the staging area:
+
+```sh
+git add path/to/changed/files/
+```
+
+Then make the commit.
+Your commit message should follow the
+[Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
+specification.
+Briefly, each commit should start with one of the approved types such as
+`feat`, `fix`, `docs`, etc. followed by a description of the commit.
+Take a look at the [Conventional Commits specification](https://www.conventionalcommits.org/en/v1.0.0/#summary)
+for more detailed information about how to write commit messages.
+
+
+```sh
+git commit -m 'feat: create function for awesome feature'
+```
+
+pre-commit will enforce that your commit message and the code changes are
+styled correctly and will attempt to make corrections if needed.
+
+> Check for added large files..............................................Passed
+> Fix End of Files.........................................................Passed
+> Trim Trailing Whitespace.................................................Failed
+> - hook id: trailing-whitespace
+> - exit code: 1
+> - files were modified by this hook
+>
+> Fixing path/to/changed/files/file.txt
+>
+> codespell................................................................Passed
+> style-files..........................................(no files to check)Skipped
+> readme-rmd-rendered..................................(no files to check)Skipped
+> use-tidy-description.................................(no files to check)Skipped
+
+In the example above, one of the hooks modified a file in the proposed commit,
+so the pre-commit check failed. You can run `git diff` to see the changes that
+pre-commit made and `git status` to see which files were modified. To proceed
+with the commit, re-add the modified file(s) and re-run the commit command:
+
+```sh
+git add path/to/changed/files/file.txt
+git commit -m 'feat: create function for awesome feature'
+```
+
+This time, all the hooks either passed or were skipped
+(e.g. hooks that only run on R code will not run if no R files were
+committed).
+When the pre-commit check is successful, the usual commit success message
+will appear after the pre-commit messages showing that the commit was created.

+> Conventional Commit......................................................Passed
+> [iss-10 9ff256e] feat: create function for awesome feature
+> 1 file changed, 22 insertions(+), 3 deletions(-)
+
+Finally, push your changes to GitHub:
+
+```sh
+git push
+```
+
+If this is the first time you are pushing this branch, you may have to
+explicitly set the upstream branch:
+
+```sh
+git push --set-upstream origin iss-10
+```

+> Total 4 (delta 3), reused 0 (delta 0), pack-reused 0
+> remote: Resolving deltas: 100% (3/3), completed with 3 local objects.
+> remote:
+> remote: Create a pull request for 'iss-10' on GitHub by visiting:
+> remote: https://github.com/CCBR/reneeTools/pull/new/iss-10
+> remote:
+> To https://github.com/CCBR/reneeTools
+>
+> [new branch] iss-10 -> iss-10
+> branch 'iss-10' set up to track 'origin/iss-10'.
+
+We recommend pushing your commits often so they will be backed up on GitHub.
+You can view the files in your branch on GitHub at
+`https://github.com/CCBR/reneeTools/tree/`
+(replace `` with the actual name of your branch).
+
+### Create the PR
+
+Once your branch is ready, create a PR on GitHub:
+
+
+Select the branch you just pushed:
+
+![Create a new PR from your branch](./img/new-PR.png)
+
+Edit the PR title and description.
+The title should briefly describe the change.
+Follow the comments in the template to fill out the body of the PR, and
+you can delete the comments (everything between ``) as you go.
+When you're ready, click 'Create pull request' to open it.
+
+![Open the PR after editing the title and description](./img/create-PR.png)
+
+Optionally, you can mark the PR as a draft if you're not yet ready for it to
+be reviewed, then change it later when you're ready.
+
+### Wait for a maintainer to review your PR
+
+We will do our best to follow the tidyverse code review principles:
+.
+The reviewer may suggest that you make changes before accepting your PR in
+order to improve the code quality or style.
+If that's the case, continue to make changes in your branch and push them to
+GitHub, and they will appear in the PR.
+
+Once the PR is approved, the maintainer will merge it and the issue(s) the PR
+links will close automatically.
+Congratulations and thank you for your contribution!
+
+### After your PR has been merged
+
+After your PR has been merged, update your local clone of the repo by
+switching to the main branch and pulling the latest changes:
+
+```sh
+git checkout main
+git pull
+```
+
+It's a good idea to run `git pull` before creating a new branch so it will
+start from the most recent commits in main.
