   - **DO NOT** install `recovery.img`. LineageOS Recovery is horrible, TWRP is great. Use TWRP. Thanks. If you mistakenly install `recovery.img` anyway, getting rid of it requires use of heimdall to flash back TWRP `recovery.img` (`heimdall flash --RECOVERY <twrp-recovery>.img`)
 
   - Install only contents of LineageOS zip file `lineage-18.1-YYYYMMDD-UNOFFICIAL-s5neolte.zip` using TWRP
-  
+
   - I use `ccache` with setting `10G`
 
   - You may already have `repo` command pre-installed on your system
-  
+
   - Use command `repo init -u https://github.com/LineageOS/android.git -b lineage-18.1`
-

   - `./extract-files.sh` commands relative to LineageOS source dir:
-  
+
     - `device/samsung/universal7580-common/extract-files.sh`
-    
+
     - `device/samsung/s5neolte/extract-files.sh`
-  
+
     - Both must be executed
-  
+
   - In order to `./extract-files.sh` commands fully succeed, you must have Samsung Android `6.0.1` preinstalled on your phone. Otherwise you get errors for missing files.

 ## LineageOS requirements for s5neolte
 
 - If you have original Samsung Android OS installed, it must be version `6.0.1`. LineageOS installation on phones using older Android versions (`5.1.1`, etc.) simply fails.
 
   - If you do not have Android `6.0.1` , get official Samsung update with [samloader](https://github.com/nlscc/samloader). Extract `zip` and `tar.md5` files, until you get all required `.img` and `.bin` files. Flash extracted `.bin` and `.img` files with [heimdall](https://github.com/Benjamin-Dobell/Heimdall)
-  
+
     - Samloader [Arch Linux PKGBUILD (AUR)](https://aur.archlinux.org/packages/samloader-git/)
-  
+
     - Take backup with TWRP before issuing `heimdall` commands
 
     - Relevant files are as follows: `boot.img`, `system.img`, `userdata.img`, `cm.bin`, `param.bin`, `sboot.bin`, `modem.bin`, `cache.img`, `hidden.img`
-    
+
       - If you use custom recovery such as TWRP, **do not** flash `recovery.img`
 
       - File `S5NEOLTE_<XXX>_OPEN.pit` is a partition definition file. You may extract one directly from your phone using `heimdall`, as well.
-      
+
     - You must patch heimdall to successfully flash your Samsung S5 Neo phone. Compile heimdall, and apply patch file [misc/heimdall/patch_filepartindex.patch](misc/heimdall/patch_filepartindex.patch). See [this GitHub issue](https://github.com/Benjamin-Dobell/Heimdall/issues/347) for details.

 - You may build parts of LineageOS using `mm` and `mmm` commands after sourcing `build/envsetup.sh`
 
   - This is useful for partial patches
+
+  - For instance, building only `Dialer` APK, run `mmm packages/apps/Dialer` in lineage source root dir
