+Here are the instructions below for running the server locally on linux.
 
 ## Build Requirements
 
-Enet development files:
+_Instructions are for Fedora Linux_
 
-`dnf install enet-devel`
+Install dependencies:
 
-
-G++
-
-`dnf install g++`
+`dnf install enet-devel g++`
 
 For testing:
 
 `dnf install gtest gmock gmock-devel gtest-devel`
+
+## Building Server
+
+Within the server directory run: `bash build.sh`
+
+## Running Tests
+
+Within the server directory run: `bash run_tests.sh`
+
+## Running Server
+
+If you have already built the server, you can run the binary location at `builds/server.out`, otherwise within the server directory, you can run `run_build.sh` to build and run the server.
+
+# Running in Docker
+
+A `Dockerfile` is provided in this project. So you can run `docker build -t defend-together .` and then `docker run -p 7777:7777 defend-together` to run locally on port `7777` in docker.
