+# CREDITS
+
+This project includes ideas and adapted code from several open-source projects.\
+In most cases the original code has been modified, optimized, or extended.
+
+## Symbol palette
+
+The symbol palette feature is based on the original Overleaf implementation:
+
+https://github.com/overleaf/web/tree/master/frontend/js/features/symbol-palette
+
+The original code was slightly improved, particularly in the parts related to keyboard input.
+
+## LDAP authentication
+
+LDAP authentication was inspired by:
+
+https://github.com/smhaller/ldap-overleaf-sl
+
+The project provided the idea and part of the implementation for adding LDAP users to the user's contacts.
+
+## Autocomplete of reference keys
+
+Autocomplete of reference keys is based on:
+
+https://github.com/lcpu-club/overleaf
+
+The implementation largely follows the referenced code, except that a different `.bib` file parser is used.
+
+## Real-time track changes and comments
+
+The Track Changes and Comments feature exists largely in the original Overleaf codebase.\
+The missing parts were implemented based on:
+
+https://github.com/ertuil/overleaf
+
+The referenced code was fixed, optimized, and extended.
+
+## Sandboxed compiles
+
+The Sandboxed Compiles feature was until recently largely present in the original Overleaf codebase.\
+The missing parts were implemented in this project.
+
+## Import file from external URL
+
+The "From External URL" feature exists in the original Overleaf code.\
+The missing proxy component was implemented in this project.
+
+## Git integration
+
+Git integration is based on:
+
+https://github.com/ayaka-notes/overleaf-pro/tree/feat-git-bridge
+
+The backend was completely rewritten.\
+The frontend uses the referenced code, which was optimized and improved.
+
+## Original Features
+
+The following features are original work implemented in this project:
+
+- Template Gallery
+- Advanced administrator tools for managing user accounts and projects
+- SAML authentication
+- OpenID Connect authentication
+
+## Acknowledgments
+
+Thanks to the users of the project for valuable feedback, suggestions,
+and help in identifying and fixing bugs.

-> [!CAUTION]
-> Overleaf Community Edition is intended for use in environments where **all** users are trusted. Community Edition is **not** appropriate for scenarios where isolation of users is required due to Sandbox Compiles not being available. When not using Sandboxed Compiles, users have full read and write access to the `sharelatex` container resources (filesystem, network, environment variables) when running LaTeX compiles.
