 ## From the Binary Releases
 
-Every release of Jalapeno provides binary releases for a variety of OSes. These binary versions can be manually downloaded and installed.
+Cross-platform binaries are provided with each release of Jalapeno. These can manually be
+downloaded and installed from [GitHub releases](https://github.com/futurice/jalapeno/releases/).
 
-1. Download your [desired version](https://github.com/futurice/jalapeno/releases)
-1. Make the binary executable (`chmod +x jalapeno-linux-amd64`)
-1. Rename and move the binary to proper location (`mv jalapeno-linux-amd64 /usr/local/bin/jalapeno`)
+In short the process is:
+
+1. Download [the latest version of jalapeno](https://github.com/futurice/jalapeno/releases/latest)
+for your platform
+2. Make the binary executable
+3. Rename and move the binary to proper location
+
+For example on MacOS (running on Apple Silicon) this can be done with:
+
+```bash
+curl -L https://github.com/futurice/jalapeno/releases/latest/download/jalapeno-darwin-arm64 -o jalapeno
+chmod +x jalapeno
+mv jalapeno /usr/local/bin/jalapeno
+```
+
+## Use via Docker
+
+It is possible to use jalapeno via Docker without installing it locally. Jalapeno image is available
+from the GitHub Container Registry, and thus the following command on a *nix system is equivalent
+to running `jalapeno` locally:
+
+MacOS and Linux:
+
+```bash
+docker run -it --rm -v $(pwd):/workdir ghcr.io/futurice/jalapeno:v0.1.4
+```
+
+Windows Command Line:
+
+```batch
+docker run -it --rm -v %cd%:/workdir ghcr.io/futurice/jalapeno:v0.1.4
+```
+
+PowerShell:
+
+```powershell
+docker run -it --rm -v ${PWD}:/workdir ghcr.io/futurice/jalapeno:v0.1.4
+```
