+# Podman OpenRC generator
+This is a simple application written in Rust to convert a simple Podman service definition in TOML format to an OpenRC service script.
+
+# Installation
+```sh
+cargo install podman-openrc
+```
+
+# Usage
+```sh
+podman-openrc <INPUT TOML FILE> <OUTPUT OPENRC FILE>
+# For example: podman-openrc input.toml output.service.sh
+```
+
+# TOML service description format
+The TOML format describing a Podman service is non-standard. It is NOT a Podlet. 
+The format is like this:
+
+```toml
+user = "<USERNAME>" # Optional property, set if you don't want to run the Podman command with the root user
+
+# Required section
+[service]
+name = "<CONTAINER NAME>" # Container name, required
+image = "<IMAGE>" # Podman image name
+network = "<NETWORK>" # Optional, if you want to run the container within a specific network. Set to "host" if you don't want to use the podman networking.
+depend = ["<SERVICE NAME>"] # Name of any service in /etc/init.d to depend on
+restart = "unless-stopped" # Restart, optional. Defaults to "unless-stopped"
+detach = true # Run container in detach mode, optional, default true. Recommended.
+hostname = "<HOSTNAME>" # Host name, optional.
+command = "<COMMAND>" # Container command to run, optional.
+
+# Optionally set one or more environment variables
+[environment]
+ASPNETCORE_ENVIRONMENT = "Test"
+# If you have a not TOML-compatible key name, use "" around the key name
+ 
+# Optionally, you can assign one or more port mappings
+[[ports]]
+host = 80 # Port on your computer
+container = 8080 # Port inside the container
+protocol = "tcp" # Protocol, optional
+
+# Optionally you can also assign volumes
+[[volumes]]
+volume = "<VOLUME NAME>" # Volume name or path on host
+path = "<PATH>" # Volume location/target inside container
+
+# Or you can make more advanced volumes with mounts
+[[mounts]]
+typ = "bind" # Mount type
+source = "/etc/hosts" # Source file
+target = "/etc/hosts" # Target file
+read_only = true # Whether to use ro mode, optional
+
+# Optionally you can use Podman secrets in an array
+[[secrets]]
+key = "<SECRET KEY>" # Secret key used in `podman secret`
+target = "<TARGET SECRET FILE>" # Target secret filename in /var/run/secrets. Optional, defaults to the key
+
+# Optionally, you can configure a healthcheck
+[service.healthcheck]
+cmd = "<HEALTHCHECK COMMAND>" # The command or route to run/check
+interval = "5m" # Interval, optional
+start_period = "30s" # Start period (start after), optional
+retries = 3 # Max retries, optional
