 We welcome contributions to the **shiny** package. To submit a contribution:
 
 1. [Fork](https://github.com/rstudio/shiny/fork) the repository and make your changes.
 
-2. Ensure that you have signed the [individual](http://www.rstudio.com/wp-content/uploads/2014/06/RStudioIndividualContributorAgreement.pdf) or [corporate](http://www.rstudio.com/wp-content/uploads/2014/06/RStudioCorporateContributorAgreement.pdf) contributor agreement as appropriate. You can send the signed copy to jj@rstudio.com.
+2. If the change is non-trivial, ensure that you have signed the [individual](http://www.rstudio.com/wp-content/uploads/2014/06/RStudioIndividualContributorAgreement.pdf) or [corporate](http://www.rstudio.com/wp-content/uploads/2014/06/RStudioCorporateContributorAgreement.pdf) contributor agreement as appropriate. You can send the signed copy to jj@rstudio.com. For trivial changes (like typo fixes), a contributor agreement is not needed.
 
 3. Submit a [pull request](https://help.github.com/articles/using-pull-requests).
 
-We'll try to be as responsive as possible in reviewing and accepting pull requests. We appreciate your contributions!
+We generally do not merge pull requests that update included web libraries (such as Bootstrap or jQuery) because it is difficult for us to verify that the update is done correctly; we prefer to update these libraries ourselves.
+
+
+## How to make changes
+
+Before you submit a pull request, please do the following:
+
+* Add an entry to NEWS.md concisely describing what you changed.
+
+* If appropriate, add unit tests in the tests/ directory.
+
+* If you made any changes to the JavaScript files in the srcjs/ directory, make sure you build the output JavaScript files. See tools/README.md file for information on using the build system.
+
+* Run Build->Check Package in the RStudio IDE, or `devtools::check()`, to make sure your change did not add any messages, warnings, or errors.
+
+Doing these things will make it easier for the Shiny development team to evaluate your pull request. Even so, we may still decide to modify your code or even not merge it at all. Factors that may prevent us from merging the pull request include:
+
+* breaking backward compatibility
+* adding a feature that we do not consider relevant for Shiny
+* is hard to understand
+* is hard to maintain in the future
+* is computationally expensive
+* is not intuitive for people to use
+
+We will try to be responsive and provide feedback in case we decide not to merge your pull request.
+
+
+## Filing issues
+
+If you find a bug in Shiny, you can also [file an issue](https://github.com/rstudio/shiny/issues/new). Please provide as much relevant information as you can, and include a minimal reproducible example if possible.
