+# Static Website
+get a static website up and running on a VM
+
+## What is in this image
+- Includes preinstalled wget, openssh-server, curl, git and caddy binaries.
+- zinit process manager which is configured with these services:
+     - sshd: Starts OpenSSH server daemon 
+     - sshkey: Adds the user SSH key to authorized_keys, so he can log in remotely to the host which running this image.
+     - clone: Clones the git repository to `website` directory.
+     - github_branch: Checkout out to a specific branch if `GITHUB_BRANCH` env var was provided.
+     - caddyfile: Constracts the Caddyfile.
+     - caddy: Runs the caddy server.
+
+## Building
+
+in the staticwebsite directory
+
+`docker build -t {user|org}/staticwebsite .`
+
+### Convert the docker image to Zero-OS flist
+Easiest way to convert the docker image to Flist is using [Docker Hub Converter tool](https://hub.grid.tf/docker-convert), make sure you already built and pushed the docker image to docker hub before using this tool.
+
+
+## Deploying
+Easiest way to deploy a VM using the flist is to head to to our [dashboard](https://dashboard.grid.tf) and deploy a Virtual Machine by providing the flist URL.
+* make sure to provide the correct entrypoint, and required env vars.
+* another important perquisite is to have a disk mounted on `/var/lib/docker`. make sure its size is big enough to fit both the images for taiga, and the volumes which will store all the db and the media files, etc.
+
+or use the dedicated Static Website application if available, which will deploy an instance that satisfies the above perquisites.
+
+
+
+## Flist
+### URL:
+This Flist should be updated to official repo.
+```
+https://hub.grid.tf/mayarosamaa.3bot/mayarosama-staticwebsite-latest.flist
+```
+
+### Entrypoint
+- `/sbin/zinit init`
+
+### Required Env Vars
+- `SSH_KEY`: User SSH public key.
+- `GITHUB_URL`: Git Repository to be clonned.
+
+### Optional Env Vars 
+- `GITHUB_BRANCH`: The git branch that is going to be served, if not provided the default branch will be served.
+- `USER_DOMAIN`: The domain provided by the user.
+- `HTML_DIR`: The directory inside the repository that has the static files to be served.
