-# Fluidify
+# Fluidify
+
+A modern alternative to T4 — an MSBuild task that processes [Fluid](https://github.com/sebastienros/fluid) (Liquid) template files at build time to generate code, configuration, or any other text output.
+
+## Installation
+
+```shell
+dotnet add package Fluidify
+```
+
+Fluidify is a development dependency — it runs only at build time and adds nothing to your project's runtime output.
+
+## Usage
+
+Add `<Fluidify>` items to your project file. Each item points to a `.fluid` template, and any custom metadata you set becomes a template variable.
+
+```xml
+<ItemGroup>
+  <Fluidify Include="Models/Greeting.cs.fluid" Greeting="HELLO" />
+  <Fluidify Include="Config/appsettings.json.fluid" AppName="MyApp" Version="1.0.0" />
+</ItemGroup>
+```
+
+Templates use standard [Liquid syntax](https://shopify.github.io/liquid/):
+
+**Models/Greeting.cs.fluid**
+```liquid
+public static class Greeting
+{
+    public const string Value = "{{ Greeting }}, World!";
+}
+```
+
+Building the project renders each template before compilation. The output path is inferred by stripping the `.fluid` extension, so `Models/Greeting.cs.fluid` produces `Models/Greeting.cs`.
+
+Fluidify works with any text format — C#, JSON, HTML, YAML, or anything else. The `.fluid` extension is just a convention; the template itself is plain text with Liquid tags.
+
+### Custom output path
+
+Use the `Destination` metadata to write the output to a different location:
+
+```xml
+<ItemGroup>
+  <Fluidify Include="Templates/report.html.fluid"
+            Destination="Output/report.html"
+            Title="Status Report"
+            Author="MyApp" />
+</ItemGroup>
+```
+
+Relative paths are resolved from the project directory. Directories are created automatically.
+
+## How it works
+
+Fluidify registers an MSBuild target that runs before `CoreCompile`. For each `<Fluidify>` item it:
+
+1. Parses the `.fluid` file using the Fluid template engine
+2. Passes all item metadata (except `Destination`) as template variables
+3. Writes the rendered output to the inferred or specified destination
