+# @session.js/errors
+
+Session.js error classes. This module can be used to check instance of thrown errors in Session.js. All errors extend from `SessionJsError` class which itself extends from generic Error class.
+
+```ts
+import { SessionRuntimeError, SessionJsError } from '@session.js/error'
+
+try {
+  // something throws
+} catch(e) {
+  if(e instanceof SessionRuntimeError) {
+    console.error('Session.js runtime error handled')
+  } else {
+    if(e instanceof SessionJsError) {
+      console.error('It\'s not Session.js runtime error... but at least we know it\'s Session\.js error')
+    } else {
+      console.error('No idea what is this error')
+      throw e
+    }
+  }
+}
+```
+
+## Made for session.js
+
+Use Session messenger programmatically with [Session.js](https://github.com/sessionjs/client): Session bots, custom Session clients, and more.
