+
+
+**Expected behavior**
+A clear and concise description of what you expected to happen.
+
+**Screenshots**
+Add screenshots of any error screens you encountered. Bug reports without screenshots will take longer to solve, so we recommend you get some!
+
+
+**Crash dumps**
+If your bug causes a crash in Luma3DS, please upload any crash dumps generated. You can find these in `SD:/luma/dumps/armX` (`X = 9 or 11`) with the name Luma3DS's exception handlers give you.
+
+
+**System information**
+*System model* e.g. new3DS XL
+
+*System firmware version* e.g. 11.14.0 (this can be found in the System Settings applet by default)
+
+*Anemone3DS version* e.g. v2.2.0 (found in the bottom-left of Anemone3DS)
+
+*Luma3DS version* e.g. v10.2.1 (found in the menu when you hold Select on boot)
+
+
+**If you are not on the [latest version of Anemone3DS](https://github.com/astronautlevel2/Anemone3DS/releases/latest), your bug report will likely be closed. Ensure the bug occurs in the latest build!**

+A Theme and Splashscreen Manager for the Nintendo 3DS, written in C.
 
 # Dependencies
- * zlib, which can be retrieved from the [3ds_portlibs](https://github.com/devkitPro/3ds_portlibs).
- * [makerom](https://github.com/profi200/Project_CTR) and [bannertool](https://github.com/Steveice10/buildtools), which can be retrieved from [SteveIce10's](https://github.com/Steveice10) buildtools repo. These must be added to your PATH.
- * ~~[pp2d](https://github.com/BernardoGiordano/pp2d), which is included in the repo if you do a git clone --recursive.~~ Due to circumstances surrounding the privacy settings on the pp2d repo, the source files are now included directly within the repo.
- * Git needs to be on your PATH, if building in a non-*nix environment.
+ * devkitARM, which can be installed following the instructions [here](https://devkitpro.org/wiki/Getting_Started).
+ * jansson, libvorbisidec, libpng, and libarchive, which can be retrieved from [devkitPro pacman](https://devkitpro.org/viewtopic.php?f=13&t=8702).
+ * A recent build of [makerom](https://github.com/profi200/Project_CTR) and the latest release of [bannertool](https://github.com/Steveice10/bannertool). These must be added to your PATH.
+
 # Building
-First of all, make sure devkitPRO is properly installed and added to the PATH.
-After that, open the directory you want to clone the repo into, and type: `git clone https://github.com/astronautlevel2/Anemone3DS/ --recursive`.
-Instructions for installing zlib can be found on the [3ds_portlibs repo](https://github.com/devkitPro/3ds_portlibs) (its easy, just run `make` and `make install-zlib`). After also adding [makerom](https://github.com/profi200/Project_CTR) and [bannertool](https://github.com/Steveice10/buildtools) to your PATH, just enter your directory and run `make`. All built files will be in `/out/`.
+First of all, make sure devkitARM is properly installed - `$DEVKITPRO` and `$DEVKITARM` should be set to `/opt/devkitpro` and `$DEVKITPRO/devkitARM`, respectively.  
+After that, open the directory you want to clone the repo into, and execute  
+`git clone https://github.com/astronautlevel2/Anemone3DS` (or any other cloning method).  
+To install the prerequisite libraries, begin by ensuring devkitPro pacman (and the base install group, `3ds-dev`) is installed, and then install the dkP packages `3ds-jansson`, `3ds-libvorbisidec`, `3ds-libpng`, `3ds-lz4`, and `3ds-libarchive` using `[sudo] [dkp-]pacman -S <package-name>`.  
+
+After adding [makerom](https://github.com/profi200/Project_CTR) and [bannertool](https://github.com/Steveice10/buildtools) to your PATH, just enter your directory and run `make`. All built binaries will be in `/out/`.

 # Credits
-The following people contributed to Anemone3DS in some way. Without these people, Anemone3DS wouldn't exist, or wouldn't be as good as it is:
- * [Daedreth](https://github.com/daedreth), who wrote the initial implementation of theme installation code and SMDH parsing.
- * [LiquidFenrir](https://github.com/LiquidFenrir), who refactored a lot of my messy code and has been essential in development.
- * [Kenn (mattkenster)](https://github.com/mattkenster), for designing the GUI, a number of sprites used in the application, and drawing the banner and icon.
+The following people contributed to Anemone3DS in some way. Without these people, Anemone3DS wouldn't exist, or wouldn't be as good as it is: [CONTRIBUTORS.md](CONTRIBUTORS.md)

  * [Rinnegatamante](https://github.com/Rinnegatamante), whose code served as reference on theme installation.
  * [SteveIce10](https://github.com/SteveIce10), whose QR code in FBI was essential.
  * [BernardoGiordano](https://github.com/BernardoGiordano) for making pp2d, and being super responsive to feature requests and just general help.
  * [yellows8](https://github.com/yellows8) for his home menu extdump tool, which was invaluable in debugging.
  * the folks on #dev of Nintendo Homebrew, who helped with unicode shenanigans (especially [Stary2001](https://github.com/Stary2001), [Fenrir](https://github.com/FenrirWolf), and DanielKO).
- * the maintainers for all used libraries, including ctrulib, zlib, citro3d, pp2d, quirc and minizip.
+ * the maintainers for all used libraries, including but not limited to ctrulib, zlib, citro3d, pp2d, and quirc.
  * all the people who helped keep me going and motivated me to work. This includes, but is definitely not limited to:

-   The encryption/decryption parts of this source code (as opposed to the
-   non-echoing password parts) were originally written in Europe. The
-   whole source package can be freely distributed, including from the USA.
-   (Prior to January 2000, re-export from the US was a violation of US law.)
-
-   This encryption code is a direct transcription of the algorithm from
-   Roger Schlafly, described by Phil Katz in the file appnote.txt. This
-   file (appnote.txt) is distributed with the PKZIP program (even in the
-   version without encryption capabilities).
-
-   If you don't need crypting in your application, just define symbols
-   NOCRYPT and NOUNCRYPT.
-   
-   Mar 8th, 2016 - Lucio Cosmo 
-   Fixed support for 64bit builds for archives with "PKWARE" password.
-   Changed long, unsigned long, unsigned to unsigned int in 
-   access functions to crctables and pkeys

-   files using zlib + zip or unzip API
-
-   This version of ioapi is designed to access memory rather than files.
-   We do use a region of memory to put data in to and take it out of. We do
-   not have auto-extending buffers and do not inform anyone else that the
-   data has been written. It is really intended for accessing a zip archive
-   embedded in an application such that I can write an installer with no
-   external files. Creation of archives has not been attempted, although
-   parts of the framework are present.
