 If you  do not find a  binary release for your  platform, please don't
 hesitate to ask me about it, I'll add it.
 
+### Using the docker image
+
+A pre-built docker  image is available, which you can  use to test the
+app without  installing it. To download:
+
+```shell
+docker pull ghcr.io/tlinden/anydb:latest
+```
+
+To execute anydb  inside the image do something like this:
+
+```shell
+mkdir mydb
+docker run -ti  -v mydb:/db -u `id -u $USER` -e HOME=/db ghcr.io/tlinden/anydb:latest set foo bar
+docker run -ti  -v mydb:/db -u `id -u $USER` -e HOME=/db ghcr.io/tlinden/anydb:latest list -o wide
+```
+
+Here, we operate in a local  directory `mydb`, which we'll use as HOME
+inside  the  docker  container.  anydb  will  store  its  database  in
+`mydb/.config/anydb/default.db`.
+
