One of the beautiful aspects about using OER in your curriculum is that when you do, you become a part of a large community of educators who are creating and sharing their work for others to use. You don't have to start from scratch; just find content you like, modify it according to the applicable CC license guidelines, use it, and pay it forward by sharing it.

Consider the following ways you may want to modify open resources to make them more appropriate for your teaching style:

There are many tools you can use to create or modify OER, but it can be confusing to pick the one you want. Here are some tools you can consider to get you started.
The simplest way to start is by using familiar word processing tools such as Microsoft Word, Google Docs, or Libre Office. You can easily save/export these documents as a PDF or print them.
Additional low-tech options include:
Another common way to create or edit educational resources is to create a website or hosted resource. This could be in the form of a blog, a static website, or a wiki. WordPress can be a great tool for these sorts of medium-tech projects.
Additional medium-tech options include:
There are a number of platforms that provide professional tools for authoring content, and some are very easy to use. A common tool used by OER projects is PressBooks (in which this text is published), a publishing software that makes it easy to produce interactive e-books and other text-based content. Other tools, like Jupyter, may take time to master and require special expertise.
Additional high-tech options include:
The Choose a License Tool will walk you through a few questions to help you determine which freedoms and restrictions you would like to allow for your work.
The Creative Commons also has a wiki entitled, Marking your work with a CC license that can help you license your own OER.
