 ## :eyeglasses: About
 This is attempt to make full functional firmware for HiSilicon based ip cameras.
 *Full functional* in our sense is firmware that has minimum general management functions (network control),
 easy update/upgrade and some kind of web user interface. OpenWrt is only one known project, that targets embedded devices and has above features out of the box.
 
-If you are looking for development environment take a look on [BR-HisiCam](https://github.com/OpenHisiIpCam/br-hisicam).
+**At the moment project is targetted to homebrew usage or simple in house production.** 
 
-## What WRT-HisiCam is and what it is not
+### What WRT-HisiCam IS and what it IS NOT
 
-WRT-HisiCam is firmware build based on [OpenWrt](https://openwrt.org/) 
+WRT-HisiCam is firmware build based on [OpenWrt](https://openwrt.org/) with mostly same functionality across all supported platforms.
+Project is not targetted to be pushed to OpenWrt upstream, it is also developed not as fork, but as source tree modification, to simplify subsequent updates.
 
-## Chip support
+It IS NOT OpenWrt port to HiSilicon platfroms. Changing configuration may cause build fails 
+(especially packages that depends on some kernel modules, ordinary packages most probably should work, but have to be tested). 
+This means that adding new and improving existing functionality requires some technical skills and expirience.
+
+For feature requests and contribution read corresponding [section](#feature-requests-and-contribution). 
+
+If your case is rather different than this project take a look on [BR-HisiCam](https://github.com/OpenHisiIpCam/br-hisicam)
+this is our test linux enviroiment for HiSilicon SoCs, suitible for developing any projects from scratch.

+### Camera modules
+
+Support for a specific module is determined by combination of chip and cmos (electrical connection is important).
+Full support determined by detecting all used gpios and other periphery, that can be done via reverse engineering 
+(usually it is not difficult as most modules are very similar in terms of schematics).
