+# Access and Download the Source Code of Wolfree
+
+Wolfree is free and open-source software. You can access and download the source code from the following websites:
+
+1. https://try.gitea.io/wolfree
+2. https://codeberg.org/wolfree
+3. https://git.disroot.org/wolfree

+
+## The Unreliability of GitHub
+
+We do not recommend pushing the source code to GitHub. Their [DMCA Takedown Policy](https://docs.github.com/en/site-policy/content-removal-policies/dmca-takedown-policy) makes storing the source code on GitHub unreliable.
+
+## The High Availability of ForgeFed
+
+For a more reliable and collaborative development experience, we recommend using [Gitea](https://about.gitea.com/) and [Forgejo](https://forgejo.org/). These platforms support [ActivityPub](https://www.w3.org/TR/activitypub/) and [ForgeFed](https://forgefed.org/) protocols, enabling seamless collaboration and communication among developers.
+
+:::note
+If you cannot access Gitea or Forgejo, we recommend installing the [Tor Browser](https://www.torproject.org/). The Tor Browser is a reputable tool designed to bypass censorship.
