+# Description
+
+### A notice
+If you are unsure, please refer to the description on the last commit on the
+[`master`](https://github.com/paveloom-d/binder-julia/tree/master) branch.
+
+### What is this?
+
+This is a Docker image from
+[the series of images](https://github.com/orgs/paveloom-d/projects/1) based on the
+[`paveloom/binder-base`](https://github.com/paveloom-d/binder-base) image. It adds
+[the Julia programming language](https://julialang.org/) to the system. For a more formal
+description, see under the spoiler:
+
+<details>
+<summary>Content of the image</summary>
+<ul>
+  <li>
+    Base image:
+    <a href="https://github.com/paveloom-d/binder-base">paveloom/binder-base</a>
+    (0.1.1)
+  </li>
+  <li>Julia (1.5.0)</li>
+</ul>
+</details>
+
+### How do I use it?
+
+The image is hosted on [Docker Hub](https://hub.docker.com/r/paveloom/binder-julia).
+To get it, in your `Dockerfile` just specify:
+
+```dockerfile
+FROM paveloom/binder-julia:tag
+```
+
+where the `tag` is one of the following:
+
+* [0.1.0](https://github.com/paveloom-d/binder-julia/releases/tag/v0.1.0)
+
+### Can I easily see what it looks like?
+
+Absolutely. For example, here's a
+[link](https://mybinder.org/v2/gh/paveloom-d/binder-base/master?urlpath=lab) to run a
+Binder instance from the stable `master` branch. You may notice that a new kernel has been
+added.
