-# Contributing
-
-## Using the issue tracker
-The [issue tracker](https://github.com/RetroMusicPlayer/RetroMusicPlayer/issues) is the preferred channel for bug reports, feature requests and submitting pull requests, but please follow these rules:
-
-* Please **do not** derail or troll issues. Keep the discussion on topic and respect the opinions of others.
-
-* Please **do not** post comments consisting solely of "+1" or "👍". Use [GitHub's "reactions" feature](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) instead.
-
-* Please **do not** write [enhancement]/[bug]/[feature request] or similar stuff in the title of issues, as there are labels for that purpose that will be added by devs or collaborators.
-
-## Bug reports
-A bug is a _demonstrable problem_. Good bug reports are extremely helpful, so thanks!
-
-Guidelines for bug reports:
-
-* Use the GitHub issue search, check if the issue has already been reported both in the open issues and in the closed ones, if there are some missing details, add them in issue comments, without creating a new one
-* Check if the issue has been fixed — try to reproduce it using the latest available build
-* Isolate the problem — ideally create a reproducible scenario and a live example
-* Do not report multiple bugs in a single ticket, otherwise it will be confusing.
-
-A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report.

-## Q: **How do I use offline synced lyrics?**
-There are three methods for adding offline synced lyrics in Retro Music.
-
-### ***Method 1:-***
-#### STEP 1: 
-Find the time-stamped lyrics for your songs that don't have lyrics already. A time-stamped lyric looks like this, "[00:04:02] Some lyrics text" for example.
-#### STEP 2: 
-Copy these time-stamped lyrics.
-#### STEP 3: 
+#### Method 1:-

+Find the time stamped lyrics for your songs which don't have lyrics already. A time stamped lyrics looks like this, "[00:04:02] Some lyrics text" for example.
+##### STEP 2: 
+Copy these time stamped lyrics.
+##### STEP 3:

-#### STEP 4: 
+##### STEP 4:

-#### STEP 5: 
-Open lyrics and you should see your time-stamped lyrics there.
+##### STEP 5: 
+Open lyrics and you should see your time stamped lyrics there.
 
-### ***Method 2:-***
-#### STEP 1: 
-Download the time-stamped lyrics for your songs that don't have lyrics already. You can find ".lrc" files for popular songs at either of the websites given below. A time-stamped lyric looks like this, "[00:04:02] Some lyrics text" for example.
-#### STEP 2: 
-A ".lrc" is like a text file that contains the time-stamped lyrics for example, "[00:04:02] Some lyrics text". Save your time-stamped lyrics are ".lrc" file.
-#### STEP 3: 
+#### Method 2:-
+##### STEP 1: 
+Find the ".lrc" files for your songs which doesn't have lyrics already.
+##### STEP 2: 
+A ".lrc" is like a text file which contains the time stamped lyrics for example, "[00:04:02] Some lyrics text"
+##### STEP 3: 
 Now you have to rename the file you created in this way: <song_name> - <artist_name>.lrc or for better matching copy the <song_name> and the <artist_name> from the tag editor and then rename the file.
-### STEP 4: 
-Now paste the LRC files to the following path: /sdcard/Retromusic/lyrics/
-Here sdcard is your internal storage.
+##### STEP 4: 
+You have to copy or move this file into a location on the SD Card: whatever_sdcard/RetroMusic/lyrics/ and paste it there.
+Finally you will be able to see the lyrics working.
 
-### ***Method 3:- (Requires third-party app)***
-#### STEP 1:
-Download automatag or autotagger from Play Store.
-#### STEP 2:
-Find the time-stamped lyrics for your songs that don't have lyrics already. You can find ".lrc" files for popular songs at either of the websites given below. A time-stamped lyric looks like this, "[00:04:02] Some lyrics text" for example.
-#### STEP 3:
-Find your song to edit and paste the synced lyrics. 
-> These apps add those synced lyrics in the music file itself instead of creating a ".lrc file for it."

-## **Q: Equalizer is very laggy and unstable or I am getting a "No equalizer found" error. Why?**
-- The Retro music in-built equalizer was removed updates ago so the only equalizer you will have by your OEM or Android native equalizer which isn't made by us and have no control over them. So you can report those issues to your OEM so that they can provide a fix in the next updates.
-
-- If you are seeing "No Equalizer Found" in your device, this means your device doesn't have a stock equalizer "MusicFx" Equalizer. You can try using this one. It's made by AEX ROM developers.

-## **Q: Why does my library shows song files twice or no song at all?**
-If you are seeing duplication of songs in the library or no songs at all, then it's because of the Media Store issue which got affected by some other app. 
-
-***To fix this:***
-1. Head to your device settings
-
-1. Open up "Apps & notifications" (This name depends from ROM to ROM)
-
-1. Find the 'Media storage' app and clear storage (both data and cache) of it.
-
-1. Then open the Retro Music app and manually scan your music from your storage. 
-
-1. Reboot the device to refresh the media store (Not sure if this is necessary)
-
-**NOTE:** Don't panic when you will open Retro Music and see "Zero" songs there in the library. It's because you cleared Media Store which is responsible for recognising files on your device.
-___
-
-## **Q: I can't find the folder menu anymore after the latest update?**
-Head to settings -> personalise. And select folders from "library categories". If there is no option of folders, tap on reset and select folders.
-___
-
-## **Q: After updating the app to the latest version, the font got removed. Why?**
-- Retro Music's font has now been replaced with system font, which means the default font your system uses will be used by Retro Music too. It fixes all font-related issues you used to face/are facing in the app. 
-
-- With the recent Retro Music v5 release, we have a built-in optional font "Manrope font" which you can toggle from Settings > Look & Feel > Toggle "Use manrope font".
-
-- If you think the font looks ugly, then you just need to change the default font from your Android settings (or use any Magisk module). If you can't, there's nothing we can do about it.
-___
-
-## **Q: How to export playlist?**
-- ***From Retro Music:***
-
-Head to the playlists tab > tap on the three-dot menu on the playlist you want to export > save as a file.
-
-- ***From Other Music Players:***
-
-In your built-in music player, there should be an option to save that playlist as a file. Save them and import them from the file manager by opening it into retro music.
-
-> Note that such playlist must be of your offline music only since retro music is an offline music player, not an online music player. So if your playlist is of online music, it can't be opened on other offline players nor can be exported
-___
-
-## **Q: How to restore/import playlist?**
-Retro Music will automatically detect any playlist file when that playlist file is stored in internal storage/Playlist. However, if it doesn't, just open any "File manager" and open that playlist file with Retro Music.
-
-For restoring playlists successfully, the location of songs must be the same in both the "Playlist" file and in your storage. For example, If your music is in "Internal storage/Music" and the playlist file has songs location "Internal storage/Songs". Then it will not be going to work since both these locations are different.
+NOTE: Don't panic when you will open Retro Music and see "Zero" songs there in the library. It's because you cleared Media Store which is responsible for recognising files on your device.
