 This is meant to be a spot for non-changing content, to host files to allow me to share with others.  In most cases it'll be best practice to keep project-related files within the project directory and serve public static content from a webserver within that project.  
 
+### Prerequisites
+
+1. First, install [Go](https://golang.org/dl/).  
+2. Then, install [Docker](https://docs.docker.com/engine/install/ubuntu/) - see left menu for other distibutions.
+3. Finally, install [docker-compose](sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose)
+
+
+### Build Application
+
+```shell
+go build -a -ldflags '-w'
+```
+
+You may need to log out and back in afterwards to ensure the "go" command is set in your PATH environment variable, otherwise it may say it's an invalid command.
+
+### Build Container
+
+Disclaimer! If you use this, you’ll need to build the container yourself. I have a CICD pipeline setup, but my registry is used for my internal infrastructure only and is not publicly available.
+
+Because this is a staticly linked binary with no external runtime dependancies, the container literally only contains the binary file, keeping it clean and low in size (6.3MB). I never did understand why people include operating systems in containers.
+
+```shell
+docker build -t publicfileserver:latest .
+```
+
+### Example docker-compose.yml
+
+```yaml
+version: '3.7'
+
+services:
+  publicfileserver:
+    image: publicfileserver:latest
+    restart: always
+    ports:
+      - 8080:8080
+    volumes:
+      - /data/public:/public
+```
+
+In this example, data stored on your host disk /data/public would be served
+
 ## Usage
 
 ```shell
 git clone https://deadbeef.codes/steven/deadbeef.codes-publicfileserver.git
+docker build -t publicfileserver:latest .
 docker-compose up -d
 ```
