+# gmsv_file
+A simple file i/o library for Garry's Mod written in ANSI C.
+
+## Installing
+1. Go to the "Releases" of this GitHub repository.
+2. Download the latest `.dll` file for your platform.
+3. Copy that file to `garrysmod/lua/bin` of your server.
+
+## Building
+1. Install premake5
+2. Use `premake5` followed by your platform (`vs2015` for windows, `gmake` for linux).
+3. Navigate to the `project` folder.
+4. If on Windows, open the `.sln` file, in on Linux, run `make`.
+5. The compiled binary should be in the `gmsv_file/bin` folder.
+
+## Using
+The module provides barebones functionality for file manipulation. It's being worked on, more features are coming soon!
+(All functions are relative to `garrysmod/` folder!!)
+
+```lua
+--- Appends contents at the end of file.
+-- @return[Boolean success]
+File.append(filename, contents)
+
+--- Deletes file.
+-- @return[Boolean success]
+File.delete(filename)
+
+--- Creates a folder with specified name.
+-- Returns false if the folder exists, or was unable to be created.
+-- @return[Boolean success]
+File.mkdir(directory)
+
+--- Reads specified file.
+-- @return[String contents]
+File.read(filename)
+
+--- Writes contents to file. Overwrites existing contents.
+-- @return[Boolean success]
+File.write(filename, contents)
+```
