 :open_file_folder: protocol generator + golang text/template (protobuf)
 
-Generic protocol buffer generator backed by Golang's [text/template](https://golang.org/pkg/text/template).
+A generic **code**/script/data generator based on [Protobuf](https://developers.google.com/protocol-buffers/).
 
 ---
 
-This is a generator plugin for the Google Protocol Buffers compiler (`protoc`).
+This project is a generator plugin for the Google Protocol Buffers compiler (`protoc`).
 
-The plugin can generate files based on a template directory using the [Golang's `text/template`](https://golang.org/pkg/text/template/) engine.
+The plugin parses **protobuf** files, generates an **ast**, and walks a local **templates directory** to generate files using the [Golang's `text/template` engine](https://golang.org/pkg/text/template/).
+
+## Philosophy
+
+* protobuf-first
+* no built-in template, only user defined templates
+* kiss, *keep it stupid simple*
+
+## Under the hood
+
+1. the *user* `protobuf` files are parsed by [`protoc`](https://github.com/google/protobuf/releases)
+2. the `ast` is generated by [`protoc-gen-go` helpers](https://github.com/golang/protobuf/tree/master/protoc-gen-go)
+3. the `ast` is given to [Golang's `text/template` engine](https://golang.org/pkg/text/template/) for each *user* template files
+4. the *funcmap* enriching the template engine is based on [Masterminds/sprig](https://github.com/Masterminds/sprig), and contains type-manipulation, iteration and language-specific helpers

+
+[Demo server](http://protoc-gen-gotemplate.m.42.am/)
 
 ## Usage
 
 `protoc-gen-gotemplate` requires a **template_dir** directory *(by default `./templates`)*.
 
-Every files ending with `.tmpl` will be processed and written in the destination folder, following the file hierarchy of the `template_dir`, and removing the `.tmpl` extension.

+| `destination_dir`     | `.`           | absolute or relative path | base path to write output
+| `single-package-mode` | *false*       | `true` or `false`         | if *true*, `protoc` won't accept multiple packages to be compiled at once (*!= from `all`*), but will support `Message` lookup across the imported protobuf dependencies
+| `debug`               | *false*       | `true` or `false`         | if *true*, `protoc` will generate a more verbose output
+| `all`                 | *false*       | `true` or `false`         | if *true*, protobuf files without `Service` will also be parsed
+
+##### Hints
+
+Shipping the templates with your project is very smart and useful when contributing on git-based projects.
+
+Another workflow consists in having a dedicated repository for generic templates which is then versioned and vendored with multiple projects (npm package, golang vendor package, ...)
 
 See [examples](./examples).
