Fix Docker build instruction example

Instead of calling perl directly from /usr/bin, set environment so that the current
default perl program is called.

+# Building with Docker
+
+The docker file will copy the local version of the site-generator program, the templates directory, the LICENSE file,
+and the site.cfg file into the Docker image. For the docker image to run correctly it needs access to your local 
+hpr.db file and the output directory (defaults to "public_html"). The default site.cfg assumes the hpr.db is located 
+in the directory from which the site-generator is run. There are two ways to make the db available to the container:
+
+* Put the hpr.db file in the public_html folder and modify the driver option under the [DBI] section of the site.cfg to:<br>
+  ```driver: dbi:SQLite:public_html/hpr.db```
+* mount the hpr.db file into the container when starting up the container with the -v option: <br>
+  ```-v <path to db directory>/hpr.db:/usr/src/app/hpr.db```
+
+Build the image by running the following command from the hpr_generator directory:
+```docker build -t hpr/site-generator .```
+
+The first build will take a while. It must pull down the base container, perl-latest, and then pull down and build the 
+various Perl modules from CPAN. After the initial build, if you have modified your site.cfg file, templates dir, or the 
+site-generator program itself, builds will be very quick.
+
+If the build fails, it is often from a CPAN module failing to download and install. Try running the Docker build command again.
+
+## Running the container
+
+When runing the Docker image, your local output directory (typically public_html) must be mounted into the container using 
+the -v option. If you are using the default path for the hpr.db, then the local hpr.db file must also be mounted into the image.
+The following is an example of running the site-generator with default locations from the hpr_generator directory:
+```
+docker run \
+-v "$(pwd)/public_html":/usr/src/app/public_html \
+-v "$(pwd)/hpr.db":/usr/src/app/hpr.db \
+hpr/site-generator --help
