 # How to use it
 Have a look at the resources folder to see how to use it.
 
+
+# Documentation
+
+## Creation
+In the creation section, you have the option to define conditions for checking whether your LXC/VM has been previously configured.  
+If all of these conditions are met, the script will proceed directly to the deploy section and execute the necessary steps to update it. *(This indicates that your LXC/VM has already been configured, and we want to avoid erasing any existing settings/config.)*  
+However, if **any** of the conditions fail to match, the script will process to the creation steps section and execute **all** the commands again.  
+
+## Conditions
+### File
+The file condition will check if a file exists or not inside the LXC/VM.
+```json
+"conditions": {
+  "file": "/var/data/traefikv2/traefik.toml"
+    or
+  "files": ["/var/data/traefikv2/traefik.toml", "/var/data/config/traefikv2/docker-compose.yml"]
+}
+```
+It can be an array of file using ``["file1", "file2"]`` or just one file in double quote ``"file"``. 
+
+### Folder
+The folder condition will check if a folder exists or not inside the LXC/VM.
+```json
+"conditions": {
+  "folder": "/var/data/traefikv2"
+    or
+  "folders": ["/var/data/traefikv2", "/var/data/config/traefikv2"]
+}
+```
+It can be an array of folders using ``["folder1", "folder2"]`` or just one folder in double quote ``"file"``. 
+
+### Programs
+The programs condition will check if a program is installed or not in the LXC/VM.
+```json
+"conditions": {
+  "program": "docker"
+    or
+  "programs": ["docker", "docker-compose"]
+}
+```
+It can be an array of programs using ``["program1", "program2"]`` or just one program in double quote ``"program"``.
+
+*Note:This uses `which` to check if the program matches to anything*
+
+## Steps
+
+**Note: Paths**  
+When you have to specify a path, you can use ``/global/`` to use the global folder (`resources/<scripts|file>/`).  
+If nothing is specified, the script will use the VM/LXC folder (`resources/lxc/<id>/`).
+
+*The comments in the JSON below are only for documentation purposes and are not valid JSON, remove them before running.*
+### Script
+The script step will execute a script.
+```json
+"steps": [
+  {
+    "type": "script",
+    "path": "/global/install-docker.sh" # local path (here: resources/scripts/install-docker.sh)
+  }
+]
+```
+
+### File
+The file step will copy a file to the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "file",
+    "path": "traefik.toml", # local path (here: resources/lxc/<id>/traefik.toml)
+    "destination": "/var/data/traefikv2/traefik.toml" # lxc/vm path
+  }
+]
+```
+
+### Folder
+The folder step will copy a folder to the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "folder",
+    "path": "/data/", # local path (here: resources/lxc/<id>/data/)
+    "destination": "/var/data/traefikv2" # lxc/vm path
+  }
+]
+```
+
+### Command
+The command step will execute a command on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "command",
+    "command": "whoami", # command to execute
+    "working_directory": "/var/data/config/traefikv2" # lxc/vm path
+  }
+]
+```
+
+### Docker
+The docker step will execute a docker command on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "docker",
+    "command": "run -d --name=traefikv2 --restart=always -p 80:80 -p 443:443 -p 8080:8080 -v /var/data/traefikv2:/etc/traefik -v /var/data/config/traefikv2:/config -v /var/run/docker.sock:/var/run/docker.sock traefik:latest", # docker command to execute
+    "working_directory": "/var/data/config/traefikv2" # lxc/vm path
+  }
+]
+```
+
+### Docker-compose
+The docker-compose step will execute a docker-compose command on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "docker-compose",
+    "command": "up -d", # docker-compose command to execute
+    "working_directory": "/var/data/config/traefikv2" # lxc/vm path
+  }
+]
+```
+*Note : Here, why not use the `command` step? Docker Compose can sometimes be executed with `docker-compose` or `docker compose`, the script will take care of choosing the correct one.*
+
+### Git
+The git step will clone a git repo on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "git",
+    "url": "https://git.abc.xyz/abc/abc.git", # git url
+    "destination": "/root/" # lxc/vm path
+  }
+]
+```
+*Note: At the the moment, no authentication is supported, so only works on public repo.*
+
+### Download
+The download step will download a file on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "download",
+    "url": "https://git.abc.xyz/file.tar.gz", # download url
+        or
+    "urls": ["https://git.abc.xyz/file1.tar.gz", "https://git.abc.xyz/file2.tar.gz"] # download urls
+    "destination": "/tmp/" # lxc/vm path
+  }
+]
+```
+
+### Extract archive (tar/zip)
+The unzip step will unzip a file in the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "unzip",
+    "path": "/tmp/file.tar.gz", # lxc/vm path to the archive
+    "destination": "/var/data/config/traefikv2" # (optional) lxc/vm path to extract the archive, will use archive parent directory if blank
+  }
+]
+```
+*Note : At the the moment, only tar and zip are supported.*
+
+### Install package
+The install-package step will install a package on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "install-package",
+    "package": "git" # package to install
+        or
+    "packages": ["git", "docker"] # packages to install
+  }
+]
+```
+*Note : At the the moment, only apt, apk, dnf, yum are supported.*  
+*Warning : Packages can have different names depending on the Linux distribution.*
+
+### Remove package
+The remove-package step will remove a package on the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "remove-package",
+    "package": "git" # package to remove
+        or
+    "packages": ["git", "docker"] # packages to remove
+  }
+]
+```
+*Note : At the the moment, only apt, apk, dnf, yum are supported.*  
+*Warning : Packages can have different names depending on the Linux distribution.*
+
+### Reboot
+The reboot step will reboot the VM/LXC.
+```json
+"steps": [
+  {
+    "type": "reboot"
+  }
+]
+```
+
+### Replace in file
+The replace-in-file step will replace a string in a file.
+```json
+"steps": [
+  {
+    "type": "replace-in-file",
+    "path": "/var/data/config/traefikv2/traefik.toml", # lxc/vm path to the file
+        or
+    "paths": ["/var/data/config/traefikv2/traefik.toml", "/var/data/config/traefikv2/traefik2.toml"] # lxc/vm paths to the files
+    "search": "abc", # string to search
+    "replace": "xyz" # string to replace
+  }
+]
+```
