+# Wolfree instances that do not bypass paywalls
+
+Wolfree is a free and open-source software for accessing the calculation results computed by Wolfram Alpha. Wolfree operates through a network of websites known as "instances." Unlike most instances, this instance **does not bypass paywalls**.
+
+<FormCTA autoFocus={true} submitText="Compute Input" />
+
+## How to access the calculation results generated by Wolfram Alpha
+
+<form onSubmit={submitMathInputForm}>
+
+1. Type your math problem in the text box.
+
+   <InputMathProblems autoFocus={false} defaultValue="y'=y" />
+
+2. Click the "Compute Input" button.
+
+   <SubmitButton text="Compute Input" />
+
+3. Explore the calculation result provided. 🎉
+
+</form>
+
+## The problem with other Wolfree instances
+
+Most other Wolfree instances can bypass paywalls, which raises concerns about Microsoft GitHub's [DMCA Takedown Policy](https://docs.github.com/en/site-policy/content-removal-policies/dmca-takedown-policy). Unfortunately, this means that developers of [LibRedirect](https://libredirect.github.io/) cannot redirect users to such instances. For details about this issue, refer to [issue #425](https://github.com/libredirect/browser_extension/issues/425) on Microsoft GitHub.
+
+## How this instance resolves the problem
+
+Unlike most Wolfree instances, this instance prioritizes ethical values and **does not bypass paywalls**.
+
+## Mirror sites
+
+Wolfree operates through a network of mirror sites. If you can't access this web page, visit the [mirror sites](/mirror).
+
+<ButtonLink to="./mirror" text="Access mirror sites" />
+
+## Source code
+
+Wolfree is **free** and **open-source** software built on transparency and openness, welcoming individuals from diverse backgrounds to collaborate on [source code](/source). ❤️
+
+<ButtonLink to="./source" text="Explore source code" />
+
+## How it works
+
+1. Install [LibRedirect](https://libredirect.github.io/) on your web browser.
+2. Enable auto-redirection from Wolfram to this instance.
+3. Enjoy accessing Wolfree instances that **do not bypass paywalls**.
+
+## Key benefits
+
+### Compliance with Microsoft GitHub
+
+This instance **does not bypass paywalls**, resolving [the GitHub issues](https://github.com/libredirect/browser_extension/issues/425) LibRedirect developers encounter.
+
+### Auto-redirection
+
+Once you install LibRedirect on your web browser, you can enable auto-redirection from Wolfram to this instance.
+
+### Cyber Ethics
+
+By accessing this instance, you actively promote ethical practices and support the work of content creators.
+
+## Get started now
+
+Install LibRedirect and enable auto-redirection. Enjoy Wolfree instances that **do not bypass paywalls**.

+# Mirror sites: alternative instances
+
+Wolfree operates through a network of mirror sites. If you can't access this web page, visit the mirror sites.
+
+1. https://gqq.gitlab.io/
+2. https://jqq.gitlab.io/
+3. https://rqq.gitlab.io/
+4. https://sqq.gitlab.io/
+5. https://uqq.gitlab.io/
+
+## Fetching JSON list of instances
+
+If you have programming knowledge, you can deserialize the [instances.json](pathname://../instances.json) file.
+
+## Accessing Wolfree in censored countries
+
+If you cannot access any of the mirror sites, we recommend installing the [Tor Browser](https://www.torproject.org/) to bypass censorship.
