+hasknote
+========
+
+A Haskell clone of [tasknote](https://github.com/mikebobroski/tasknote) with extra features and nicer configuration. It allows the user to associate a text file with a [Taskwarrior](https://taskwarrior.org/) task. When a note is added, the task will be annotated with the first line of the note. This annotation will be updated with each call to `hasknote edit`.
+
+## Installation
+
+### Building with Nix
+
+Using the [Nix package manager](https://nixos.org/nix/):
+
+1. Clone the project and `cd` into its directory.
+2. Run `nix build`
+3. The compiled executable will be located at `./result/bin/hasknote`.
+
+### Building with Cabal
+
+Using Haskell's [Cabal](https://www.haskell.org/cabal/):
+
+1. Clone the project and `cd` into its directory.
+2. Run `cabal --enable-nix v1-configure && cabal --enable-nix v1-build`.
+3. The compiled executable will be located at `./dist/build/hasknote/hasknote`.
+
+## Usage
+
+```
+Usage: hasknote TASK_ID COMMAND
+
+Available options:
+  -h,--help                Show this help text
+
+Available commands:
+  edit [--stdin]           Create or edit a note for a task, optionally reading
+                           from stdin instead of opening an editor
+  view                     View the note for a task if it exists
+  remove                   Remove the note for a task if it exists
+```
+
+## Configuration
+
+You can configure hasknote via a `~/.hasknoterc` file. Options are:
+
+- `editor` - The text editor you edit your note in. Default: `editor = vi`.
+- `viewer` - The program used to view your note. Default: `viewer = cat`.
+- `location` - The directory where your notes will be stored. If the directory does not exist, it will be created. Default: `location = ~/.task/notes`.
+- `extension` - The file extension for your notes. Default: `extension = .txt`.
+- `prefix` - The prefix of hasknote's task annotations, used by hasknote to detect and remove the annotations later. Default: `prefix = [hasknote]`.
