+### How do I use custom certificates?
+
+Y need to mount custom certificates into container like this:
+
+```yml
+volumes:
+    ....
+    ./ca1.crt:/usr/local/share/ca-certificates/ca1.crt:ro
+    ./ca2.crt:/usr/local/share/ca-certificates/ca2.crt:ro
+    ....
+```
+
+Then, restart the container, which runs `update-ca-certificates` on startup, adding local certificates into system certificate store.

 ### How do I make this work on Raspberry Pi?
 
 You won't be able to use official Docker Hub images, those are amd64 only. Use dynamic setup (master branch of this repository) instead.
