+# Installation
+
+1. Clone the Conquest repository
+```
+git clone https://github.com/jakobfriedl/conquest
+cd conquest
+```
+
+2. Install Nim.
+
+```bash
+curl https://nim-lang.org/choosenim/init.sh -sSf | sh
+```
+
+3. The Conquest binaries for team server and client are designed to be compiled on a UNIX system using the `nimble` command. This command installs and updates all dependencies and third-party libraries automatically.
+```
+nimble server
+nimble client
+```
+
+4. Start the Conquest team server with a C2 profile. The default profile is located in data/profile.toml and can be adapted by the operator.
+```
+bin/server -p data/profile
+```
+
+On the first start, the Conquest team server creates the Conquest database in the data directory, as well as the team server's private key in data/keys, which is used for the key exchange between team server, client and agent.

+
+5. Start the Conquest operator client
+```
+bin/client
+```
+
+By default, the Conquest client connects to localhost:37573 to connect to the team server. The address and port can be specified from the command-line using the `-i` and `-p` flags. The team server port is specified in the malleable C2 profile.
+
+```
+bin/client -i <team-server-address> -p <team-server-port>
+```
