+### use inside a container
+
+`gomplate` is often used inside Docker containers. When building images with Docker 17.05 or higher, you can use [multi-stage builds][] to easily include the `gomplate` binary in your container images.
+
+Use the `COPY` instruction's `--from` flag to accomplish this:
+
+```Dockerfile
+...
+COPY --from=hairyhenderson/gomplate:v2.5.0-slim /gomplate /bin/gomplate
+```
+
+Now, `gomplate` will be available in the `/bin` directory inside the container image.
+
+Note that when using `gomplate` with HTTPS-based datasources, you will likely need to install the `ca-certificates` package for your base distribution. Here's an example when using the [`alpine`](https://hub.docker.com/_alpine) base image:
+
+```Dockerfile
+FROM alpine
+
+COPY --from=hairyhenderson/gomplate:v2.5.0-slim /gomplate /bin/gomplate
+RUN apk add --no-cache ca-certificates
+```

+### Slim binaries
+
+As a convenience, self-extracting compressed `gomplate` binaries are available from the [releases][] page. These are named with `-slim` as a suffix (or `-slim.exe`). They are compressed with [UPX][].
+
+Generally, these binaries are ~5x smaller than the regular ones, but are otherwise exactly the same.
+
+There are a few reasons that a regular binary is also distributed:
+- UPX lacks support for some platforms
+- there's a very slight chance that the slim binary could exhibit some form of bug related to being compressed
+- there could be environments where self-extracting compressed executables are disallowed
