 ## Licensing
 
-Sentry is using [FSL (Functional Source License)](https://fsl.software/). Although it's not an OSI-approved license, the source code of Sentry and its' surrounding service & libraries for self-hosted deployment are open and [available on GitHub](https://github.com/orgs/getsentry/repositories?q=has%3Atag-production). For self-hosted, this license means that users can use Sentry and deploy it anywhere (even inside an enterprise ecosystem), but users are prohibited to sell deployed self-hosted Sentry as any kind of offering (SaaS or any kind of business model) and users are prohibited to be a direct competitor of Sentry by using Sentry's code that is FSL-licensed.  After two years, the license converts to Apache 2.0 or MIT.
