 ## Security Issues
 
-The IPFS protocol and its implementations are still in heavy development. This means that there may be problems in our protocols, or there may be mistakes in our implementations. And -- though IPFS is not production-ready yet -- many people are already running nodes in their machines. So we take security vulnerabilities very seriously. If you discover a security issue, please bring it to our attention right away!
-
-If you find a vulnerability that may affect live deployments -- for example, by exposing a remote execution exploit -- please send your report privately to security@ipfs.io. Please DO NOT file a public issue.
-
-If the issue is a protocol weakness that cannot be immediately exploited or something not yet deployed, just discuss it openly.
+Please follow [`SECURITY.md`](SECURITY.md).
 
 ## Install

 The snap sets `IPFS_PATH` to `SNAP_USER_COMMON`, which is usually `~/snap/ipfs/common`. If you want to use `~/.ipfs` instead, you can bind-mount it to `~/snap/ipfs/common` like this:
 
-```sudo mount --bind ~/.ipfs ~/snap/ipfs/common```
+```
+$ sudo mount --bind ~/.ipfs ~/snap/ipfs/common
+```
 
 If you want something more sophisticated to escape the snap confinement, we recommend using a different method to install `go-ipfs` so that it is not subject to snap confinement.

+If you find a vulnerability that may affect live deployments -- for example, by
+exposing a remote execution exploit -- please **send your report privately** to
+security@ipfs.io. Please **DO NOT file a public issue**.
+
+If the issue is a protocol weakness that cannot be immediately exploited or

+## Reporting a non security bug
+
+For non-security bugs, please simply file a GitHub [issue](https://github.com/ipfs/go-ipfs/issues/new/choose).
