 # Bibliofile
-### A TUI-based ebook reader that hopefully doesn't suck!
+### A TUI-based ebook reader inspired by NCurses-era programs!
 
-A long long time ago, I was in college. I frequently bought the ebook versions of my textbooks, but to my dismay...most ebook readers sucked. The user interface was complicated, dark mode was unavailable for most readers until I neared graduation, dark mode usually looked terrible even if it was available, etc. I hope to change that. What better dark mode that running it on the TUI? What better way to make a simple UI than to design one myself that *I* like?
+Bibliofile is a simplified epub reader with automatic bookmarking!
 
-This is very much a personal project. Rust isn't exactly used for big companies besides Mozilla just yet, and progress is slow-going due to my personal and work commitments. Still, when it is done, I will attempt to release it on several popular repositories such as Flatpack so that others can use it.
+Instructions:
 
-Feel free to check up on progress on my blog, www.whoisthisjoker.com. I post there periodically to talk about what direction I want the project to go.
+ - installation
+ - use
+ - feedback
+
+
+
+ ## installation
+
+ At the moment, Bibliofile is a work-in-progress, so it is not part of any package manager, and no binaries are available at the moment. However to run this while in alpha, you can follow the Instructions down below.
+
+ ### 1
+
+ Install Rust. The full Instructions on how to do this are here: https://www.rust-lang.org/tools/install
+
+ The easiest way of installing Rust is with the following command:
+
+ ```bash
+ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+ ```
+
+
+ ### 2
+
+ Clone the repository to the directory of your choice
+
+ ```git
+ git clone https://git.whoisthisjoker.com/daniel/bibliofile
+ ```
+
+ ### 3
+
+cd into the directory *bibliofile*. Compile the program. This is best done with cargo.
+
+ ```rust
+ cargo build
+ ```
+
+ The executable will be in target/debug.
+
+ Please keep in mind, at this point in development compilation success is not guaranteed.
+
+ ## running
+
+ Running the program is simple, as at this point there is not many features. Simply run
+
+ ```bibliofile [booknamehere.epub]```
+
+There will be buttons at the bottom of each page that allow you to turn pages. Simply press "last" or "next" to turn the page.
+
+
+## disclamers
+
+This program is in alpha, and I am trying to get base functionality working. It will be lacking features, and can currently only read epub files. Mobi and PDF are not supported.
