-## Usage
+## Commands
+
+### `tera-render`
+
+Render Tera templates with structured data from Nushell pipelines or arguments.
 
 ```nushell
-> tera-render <template> (context)
+> tera-render <template> [context]
 ```
 
-Flags:
+**Parameters:**
+- **template** `<path>`: Path to the `.tera` template file
+- **context** `<any>`: Context data (record or JSON file path) (optional)
+
+**Flags:**
 - **-h**, **--help**: Display the help message for this command
 
-Parameters:
-- **template** <path>: Ruta al archivo .tera
-- **context** <any>: Datos de contexto (record o JSON path) (optional)
+## Template Syntax
 
+Tera uses a Jinja2-inspired syntax with powerful features:
 
-### Examples
+### Basic Variables
+```jinja2
+Hello, {{ name }}!
+Your age is {{ age }}.
+```
 
-Render **template.tera** with a record as context from the pipeline.
+### Control Structures
+```jinja2
+{% if user.is_admin %}
+  <p>Welcome, admin!</p>
+{% else %}
+  <p>Welcome, user!</p>
+{% endif %}
 
+{% for item in items %}
+  - {{ item.name }}: {{ item.value }}
+{% endfor %}
+```
+
+### Filters
+```jinja2
+{{ name | upper }}
+{{ price | round(precision=2) }}
+{{ date | date(format="%Y-%m-%d") }}
+```
+
+### Macros
+```jinja2
+{% macro render_field(name, value) %}
+  <div class="field">
+    <label>{{ name }}</label>
+    <span>{{ value }}</span>
+  </div>

+### Pipeline Data Processing
 
+```nushell
+# Process system information
+> sys | tera-render system-report.tera
+
+# Generate configuration files from structured data
+> {
+    server: {
+      host: "localhost",
+      port: 8080,
+      ssl: true
+    },
+    database: {

+    }
+  } | tera-render config.tera
+
+# Process CSV data
+> open employees.csv
+  | tera-render employee-report.tera

+
+### Multiple Data Sources
+
+```nushell
+# Using JSON file as context
+> tera-render template.tera data.json
+
+# Using record from pipeline
+> { name: 'Akasha', projects: [ {'name': 'TheProject', 'status': 'active'} ] }
+  | tera-render template.tera
+
+# Wrapping data for template access

+
+### Configuration File Generation
+
+**nginx.conf.tera**
+```jinja2

+## Workflow Examples
+
+### CI/CD Pipeline Configuration
+
+```nushell
+# Generate Kubernetes manifests
+def generate-k8s-manifests [env: string] {
+    let config = (open $"configs/($env).json")
+
+    [
+        "deployment.yaml.tera",

+        $output | save $"manifests/($env)/(($template | str replace '.tera' ''))"
+    }
+}
+
+# Generate environment-specific configs
+def generate-env-configs [] {
+    ["dev", "staging", "prod"] | each { |env|
+        let base_config = (open base-config.json)
+        let env_config = (open $"($env)-config.json")
+        let merged = ($base_config | merge $env_config)
+
+        $merged | tera-render app-config.yaml.tera | save $"configs/($env).yaml"
+    }
+}
+```
+
+### Content Management
+

+    ls content/*.json
+    | each { |post_file|
+        let post_data = (open $post_file.name)
+        let filename = ($post_file.name | path basename | str replace '.json' '.html')
+
+        $post_data | tera-render blog-post.html.tera | save $"output/($filename)"
+    }
+}
+
+# Generate navigation menus
+def generate-navigation [site_config: string] {
+    open $site_config
+    | get pages
+    | tera-render navigation.html.tera
+    | save includes/navigation.html
+}
+```
+
+### Infrastructure as Code
+
+```nushell
+# Generate Terraform configurations
+def generate-terraform [environment: string] {
+    let vars = (open $"terraform/($environment).tfvars.json")
+
+    ls terraform/templates/*.tf.tera
+    | each { |template|
+        let output_name = ($template.name | path basename | str replace '.tera' '')
+        $vars | tera-render $template.name | save $"terraform/($environment)/($output_name)"
+    }
+}
+
+# Generate Docker Compose files
+def generate-docker-compose [services: list] {
+    let compose_data = {
+        services: $services,
+        networks: ["app-network"],
+        volumes: ["db-data", "app-logs"]
+    }
+
+    $compose_data | tera-render docker-compose.yml.tera | save docker-compose.yml
+}
+```
+
+## Integration with Nushell Data Processing
+
+Leverage Nushell's powerful data manipulation with Tera templating:
+
+```nushell
+# Process and template CSV data
+> open sales.csv
+  | group-by region
+  | transpose region sales
+  | insert total { |row| $row.sales | math sum }
+  | tera-render sales-report.html.tera
+  | save reports/sales-summary.html
+
+# Combine multiple data sources
+> let weather = (http get "https://api.weather.com/current")
+> let system = (sys)
+> {weather: $weather, system: $system}
+  | tera-render dashboard.html.tera
+
+# Batch process templates
+> ls templates/*.tera
+  | each { |template|
+      let data = (open $"data/(($template.name | path basename | str replace '.tera' '.json'))")
+      $data | tera-render $template.name
+    }
+```
+
+## Error Handling
+
+The plugin provides detailed error messages for common issues:
+
+```nushell
+# Template syntax errors
+> {} | tera-render broken-template.tera
+Error: Template error
+  ╭─[calling tera-render]
+  │ Template parse error: Unexpected token...
+
+# Missing variables
+> {} | tera-render template-with-vars.tera
+Error: Render error
+  ╭─[calling tera-render]
+  │ Variable 'name' not found in context
+
+# File not found
+> {} | tera-render nonexistent.tera
+Error: Read error
+  ╭─[calling tera-render]
+  │ Failed to read file 'nonexistent.tera': No such file...
+```
+

+
+## Template Best Practices
+
+### 1. Organize Templates
+```
+templates/
+├── base.html.tera          # Base layouts
+├── components/
+│   ├── header.html.tera    # Reusable components
+│   └── footer.html.tera
+├── pages/
+│   ├── home.html.tera      # Page templates
+│   └── about.html.tera
+└── configs/
+    ├── nginx.conf.tera     # Configuration templates
+    └── docker.yml.tera
+```
+
+### 2. Use Template Inheritance
+**base.html.tera**
+```jinja2
+<!DOCTYPE html>
+<html>
+<head>
+    <title>{% block title %}{{ site.title }}{% endblock %}</title>
+</head>
+<body>
+    {% block content %}{% endblock %}
+</body>
+</html>
+```
+
+**page.html.tera**
+```jinja2
+{% extends "base.html.tera" %}
+
+{% block title %}{{ page.title }} - {{ site.title }}{% endblock %}
+
+{% block content %}
+    <h1>{{ page.title }}</h1>
+    {{ page.content }}
+{% endblock %}
+```
+
+### 3. Create Reusable Functions
+```nushell
+# Template rendering helper
+def render-template [template: string, data: any] {
+    $data | tera-render $template
+}
+
+# Batch template processing
+def render-all-templates [data_dir: string, template_dir: string, output_dir: string] {
+    ls $"($data_dir)/*.json"
+    | each { |data_file|
+        let basename = ($data_file.name | path basename | str replace '.json' '')
+        let template = $"($template_dir)/($basename).tera"
+        let output = $"($output_dir)/($basename).html"
+
+        if ($template | path exists) {
+            open $data_file.name | tera-render $template | save $output
+            print $"Generated: ($output)"
+        }
+    }
+}
+```
