-# In other words, the 'url' prop should be the final accessible URL seen by a user.

+
+# Option 1: With Reverse Proxy

+#   +------+      |+-------------+      +----------------+|

+#   +------+      |+-------------+      +----------------+|
+#                 +---------------------------------------+
+#
+#   You need to setup reverse proxy. (eg. Nginx)
+#   You do not define 'https' section.
+
+# Option 2: Standalone
+#
+#                 +- https://example.tld/ -+
+#   +------+      |   +---------------+    |
+#   | User | ---> |   | Misskey (443) |    |
+#   +------+      |   +---------------+    |
+#                 +------------------------+
+#
+#   You need to run Misskey as root.
+#   You need to set Certificate in 'https' section.
+
+# To use option 1, uncomment below line.
+# port: 3000    # A port that your Misskey server should listen.
+
+# To use option 2, uncomment below lines.
