+# Hemlock 🌲
+
+`hemlock` - is a CLI tool for vendoring files or directories from remote resources/repositories. It can be used for easy .proto files vendoring from multiple repositories to perform `protogen`
+
+## ⚙️ Installation
+`hemlock` can be easly installed using package manager (currently supported: brew):
+
+```bash
+brew tap MadL1me/hemlock
+
+brew install hemlock
+```
+
+## Usage
+
+Vendoring can be activated by calling main command:
+
+```sh
+hemlock
+```
+
+By default, hemlock is searching for `hemlock.yaml` config in same directory. 
+
+For example, for following hemlock.yaml config:
+
+```yaml
+version: 1
+vendor_dir: vendor
+external_deps:
+  - github.com/MadL1me/RhythmGE/src/index.scss@68f7379
+```
+
+it will create following structure:
+
+```
+vendor/
+├── index.scss@68f7379
+```
+
+### Hemlock.yaml config format
+
+```yaml
+version: 1
+vendor_dir: vendor
+external_deps:
+  - github.com/MadL1me/RhythmGE/src/index.scss@master    # would get from master branch
+  - github.com/MadL1me/RhythmGE/src/index.scss@68f7379   # would get from 68f7379 hash commit
+  - github.com/MadL1me/RhythmGE/src/index.scss           # would get from master branch by default
+
+  # you can specify http/https protocol if you want
+  - https://github.com/MadL1me/RhythmGE/src/index.scss@master   
+
+  # github permalink buttons also work as well
