+# What is Hitch?
+
+[Hitch](https://hitch-tls.org/) is a *libev-based* high performance *SSL/TLS proxy* by [Varnish Software](https://varnish-software.com). It is specifically built to terminate TLS connections at high scale and forwards unencrypted HTTP traffic to Varnish or any other HTTP backend.
+
+# How to use this image
+
+Running a Hitch Docker container can be done by using the following command:
+
+```console
+$ docker run --name=hitch -p 443:443 %%IMAGE%%
+```
+
+This container will expose port `443`, which is required for HTTPS traffic.
+
+## Configuration file and extra options
+
+Without any argument, the container will run `hitch --config=/etc/hitch/hitch.conf`. You can mount your own configuration file to replace the default one:
+
+```console
+$ docker run -v /path/to/your/config/file:/etc/hitch/hitch.conf:ro %%IMAGE%%
+```
+
+You can also change the path of the configuration file by setting the `HITCH_CONFIG_FILE` environment variable.
+
+Note that extra arguments can be added to the command line. If the first argument starts with a `-`, the arguments are added to the default command line, otherwise they are treated as a command.
+
+> Our assumption is that your backend, Varnish or other, supports both *HTTP/2* and the *PROXY* protocol.
+
+## Connecting to the backend
+
+By default Hitch will connect to the backend using `localhost:8843` using the [PROXY protocol](https://github.com/varnish/hitch/blob/master/docs/proxy-protocol.md). If your backend server *PROXY*, the two will be able to talk together and backend will be able to expose the true client IP.
+
+But you'll probably run your backend service in a separate container. In that case, you'll want to change the backend settings. You can either do that by replacing the [`backend`](https://github.com/varnish/hitch/blob/master/hitch.conf.man.rst#backend--) configuration setting in your mounted configuration file, or by adding a *command-line option*.
+
+Here's how you set the backend via a *command-line option*, assuming your backend is available through `backend.example.com` on port `8443`:
+
+```console
+$ docker run %%IMAGE%% "--backend=[backend.example.com]:8443"
+```
+
+## Setting the certificate
+
+The Hitch Docker image comes with a self-signed certificate that is stored in `/etc/hitch/certs/default`.
+
+This certificate is automatically created during *Hitch* package install, and is a self-signed certificate using 2048-bit RSA-encrypted cipher. It is set up for the `localhost` hostname, with an expiration date 30 years in the future.
+
+This certificate is only suited for testing. Using a bind mount, you can override the value of the certificate and use your own certificate, which is advisable.
+
+Here's an example:
+
+```console
+$ docker run -v /path/to/your/certificate:/etc/hitch/certs/default:ro %%IMAGE%%
+```
+
+You can also override the [`pem-file`](https://github.com/varnish/hitch/blob/master/hitch.conf.man.rst#pem-file--string) configuration setting in your mounted configuration file.
+
+If you prefer setting the certificate location on the command line, you can add the location as part of the `--backend` option.
+
+Here's how you do this:
+
+```console
+$ docker run %%IMAGE%% "--backend=[backend.example.com]:8443:/path/to/cert.pem"
+```
