-# FastDownloader
+# FastDownloader
+Download files from the internet with a simple command line interface.
+Will significantly speed up loading from sites that slow down single-threaded 
+download speeds. Applicable to cdn of sites with pirated films, for example.
+
+## Installation
+- Install [pipx](https://pypa.github.io/pipx/installation/)
+- Run `pipx install git+https://github.com/BarsTiger/FastDownloader`
+
+## Usage
+Provide direct link to file as argument.
+```
+fastdl https://example.com/big_file.zip
+```
+Use `-h` or `--help` to see all options.
+
+## Important
+Not all sites support adding a `Range` header, so if you get an error when loading - 
+it’s impossible to speed it up, try using browser downloaders. 
+For example, huggingface supports `Range` header, you can try it out. Notice that
+huggingface does not cut down the download speed, so this application most likely will 
+not help if your Internet speed is low.
