+> diadog, your loyal file dialog companion. Binaries to open native file dialogs on multiple platforms.
 
-Linux: libgtk-3-dev libdbus-1-dev
+diadog is a collection of pre-built binaries for the most common desktop platforms which enables you to open native file dialogs easily and in a standardized manner, and receive the paths selected by the user back as a string.
 
-Windows: ole32.lib uuid.lib
+This toolkit supports multiple forms of file dialogs, namely:
+- Selecting a single file
+- Selecting multiple files
+- Selecting folders
+- Selecting an output file
+
+All file-related actions can optionally be supplied with a set of allowed file extensions to restrict the user input.
+
+diadog supports the following platforms:
+- Windows x64
+- macOS x64
+- Linux x64 (with GTK)
+
+Support for more platform is planned, specifically:
+- Windows x32
+- macOS arm64
+- Linux x64 (no GTK)
+
+## Samples
+```bash
+$ dopen single
+> "/Users/test/Documents/file.pdf"
+```
+
+```bash
+$ dopen many
+> "/Users/test/Documents/file1.pdf"
+> "/Users/test/Documents/file2.pdf"
+> "/Users/test/Documents/file3.pdf"
+```
+
+```bash
+$ dsave single
+> "/Users/test/Documents/out.txt"
+```
+
+## Usage
+
+### `dopen`
+```bash
+Usage is like:
+    dopen {SUBCMD} [subcommand-opts & args]
+where subcommand syntaxes are as follows:
+
+  single [optional-params]
+    Select a single file.
+  Options:
+      -p=, --path=     string   ""  The path to open by default.
+      --packages=      strings  {}  The display name of a set of file types to match.
+      -f=, --filters=  strings  {}  The file types to match, in the order of the specified packages.
+
+  many [optional-params]
+    Select one or more files.
+  Options:
+      -p=, --path=     string   ""  The path to open by default.
+      --packages=      strings  {}  The display name of a set of file types to match.
+      -f=, --filters=  strings  {}  The file types to match, in the order of the specified packages.
+
+  folder [optional-params]
+    Select a folder.
+  Options:
+      -p=, --path=  string  ""  The path to open by default.
+```
+
+### `dsave`
+```bash
+Usage is like:
+    dsave {SUBCMD} [subcommand-opts & args]
+where subcommand syntaxes are as follows:
+
+  single [optional-params]
+    Save to a single file.
+  Options:
+      -n=, --name=     string   ""  The name to use by default.
+      -p=, --path=     string   ""  The path to open by default.
+      --packages=      strings  {}  The display name of a set of file types to match.
+      -f=, --filters=  strings  {}  The file types to match, in the order of the specified packages.
+```
+
+### Notes
+When supplying multiple filters, the first one will be used as the default file extension. For example, if you supply filters for two distinct packages for ZIP's and JPG's, in that order, the default file extension will be `.zip`.
+
+### Example Invocations
+
+#### `dopen`
+##### Setting a custom start path
+```bash
+dopen single --path="/Users/test/Documents"
+```
+
+##### Setting valid file extensions
+```bash
+dopen single --pack="Image" --filter="jpg,jpeg"
+```
+
+##### Setting multiple valid file extensions
+```bash
+dopen single --pack="Image" --filter="jpg,jpeg" --pack="Archices" --filter="zip,tar,gz,rar"
+```
+
+#### `dsave`
+##### Setting a custom start path
+```bash
+dsave single --path="/Users/test/Documents"
+```
+
+##### Setting valid file extensions
+```bash
+dsave single --pack="Image" --filter="jpg,jpeg"
+```
+
+##### Setting multiple valid file extensions
+```bash
+dsave single --pack="Image" --filter="jpg,jpeg" --pack="Archices" --filter="zip,tar,gz,rar"
+```
+
+## Building
+Building diadog
+
+### Linux
+Ensure that `libgtk-3-dev` is installed.
+```bash
+nimble build_all_linux
+```
+
+### Windows
+The recommended way is to cross-compile from Linux via MingW. No extra dependencies are required.
+```bash
+nimble build_all_windows
+```
+
+### macOS
+No extra dependencies are required.
+```bash
+nimble build_all_macos
+```
