Refactored how CMake passes version & settings info

- keys can now be passed per-build passing -DLAIKA_PUBKEY=[pubkey] & -LAIKA_PRIVKEY=[pubkey] to `cmake -B`
- if those definitions aren't passed, the default public & private key will be used (for quick testing)

 # Laika
 
-This is a simple POC botnet written in C99. The net library shares some similarities to [FoxNet](https://github.com/CPunch/FoxNet), in fact lpolllist.c is just a port of the FoxPollList class. This botnet is also crossplatform with clients written for each platform (check the /clients folder).
+Laika is a simple botnet stack for red teaming. It allows authenticated communication across a custom protocol with generated key pairs which are embedded into the executable. 
 
-## Why?
+Some notable features thus far:
+- Lightweight, the bot alone is 80kb and uses very little resources.
+- Uses obfuscation techniques also seen in the wild (string obfuscation, tiny VMs executing sensitive operations, etc.)
+- Simple configuration using CMake (setting keys, obfuscation modes, etc.)
 
-Malware development in recent years is soooooooo boring (esp. malware written by non-nationstate actors). I wanted to prove that homebrew malware can still be interesting and fun! Obviously use this on your own machines/get permission before running etc. etc.
+## Why 'Laika'?
+
+During the soviet space race, [Laika](https://en.wikipedia.org/wiki/Laika) was the first dog in space; however shortly after died of asphyxiation and overheating of the shuttle. Take whatever you want from this information.
+
+## Configuration and compilation
+
+First, compile the target normally
+
+```
+cmake -B build && cmake --build build
+```
+
+Now, generate your custom key pair using `genKey`
+
+```
+./bin/genKey
+```
+
+Next, rerun cmake, but passing your public and private keypairs
+
+```
+rm -rf build && cmake -B build -DLAIKA_PUBKEY=997d026d1c65deb6c30468525132be4ea44116d6f194c142347b67ee73d18814 -DLAIKA_PRIVKEY=1dbd33962f1e170d1e745c6d3e19175049b5616822fac2fa3535d7477957a841 && cmake --build build
+```
