 \note You might not need to build a copy of the library for Linux - precompiled deb files for 64 bit and 32 bit Debian and Ubuntu are provided in the GitHub version releases. Unless you are on a different Linux distribution which does not support the installation of deb files, or wish to submit fixes and enhancements to the library itself you should have an easier time installing the precompiled version instead.

 If you want to install the library, its dependencies, and header files to a different directory, specify this directory when running `cmake`:
 
 ```bash
-cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install
+cmake -B ./build -DCMAKE_INSTALL_PREFIX=/path/to/install

 Then once the build is complete, run `make install` to install to the location you specified.

+If you are on **Arch Linux**, you will need to add `/usr/local` to your environment variables:
+
+```bash
+export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
+export CPLUS_INCLUDE_PATH=/usr/local/include:$CPLUS_INCLUDE_PATH
+```
+
+However, if you don't want to change your environment settings, you can use these flags to compile:
+
+```bash
+g++ -std=c++17 -L/usr/local/lib -I/usr/local/include mydppbot.cpp -o dppbot -ldpp
+```
+
 The important flags in this command-line are:
 
 * `-std=c++17` - Required to compile the headers
-* `-ldpp` - Link to libdpp.so
+* `-L/usr/local/lib` - Required to tell the linker where libdpp is located.
+* `-I/usr/local/include` - Required to tell the linker where dpp headers are located.
 * `mydppbot.cpp` - Your source code
 * `dppbot` - The name of the executable to make
+* `-ldpp` - Link to libdpp.so

 To make the bot start, we must call the dpp::cluster::start method, e.g. in our program by using `bot.start(dpp::st_wait)`.

+We also add a line to tell the library to output all its log information to the console, use `bot.on_log(dpp::utility::cout_logger());` (dpp::utility::cout_logger) - if you wanted to do something more advanced, you can replace this parameter with a lambda just like all other events.
 
 The parameter which we set to false indicates if the function should return once all shards are created. Passing dpp::st_wait here tells the program you do not need to do anything once `bot.start` is called.
