 Follow these instructions even if you do not have Docker installed, just to be sure that all traces of Docker are removed from your system to avoid interference later on.

 ### Install Docker
 
-1. `sudo apt-get install ca-certificates curl gnupg lsb-release`
+1. `sudo apt-get install ca-certificates curl`
 
 This installs packages needed for the actual installation step.
 
 In order to install Docker, we need to add the package repository.
 
 2. Add Docker's official GPG key:
-   `sudo mkdir -p /etc/apt/keyrings`
-   `curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg`
+   `sudo install -m 0755 -d /etc/apt/keyrings`
+   `sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc`
+   `sudo chmod a+r /etc/apt/keyrings/docker.asc`
 
 3. Set up the repository:
-   `echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null`

+  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
+  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null`
 
 4. Update the apt index
    `sudo apt-get update`
 
 5. Install Docker, Compose, and dependencies
-   `sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin`
+   `sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin`
 
 ### Running Docker without sudo
 
 [Docker Docs Reference](https://docs.docker.com/engine/install/linux-postinstall)
 
 In order to run Docker without sudo, we need to make sure the docker group is created and that the user is added to that group.
 
-1. `sudo groupadd docker`
+1. `sudo groupadd docker` (this might tell you that the group already exists; then just move on to the next step)
 2. `sudo usermod -aG docker $USER`
 3. Log out and back in to see the changes. If you are running a virtual machine, you may need to restart the virtual machine.
 4. Make sure you can run docker without sudo: `docker ps`

+### Needed and Optional Temporary Steps
+
+Some of the steps are required, and some optional. Do both of the required steps, and the optional steps according to your need.
+
+#### Using an Older Commit (required)
+
+The latest commit (that was downloaded using the clone command above) does not currently run without errors. To get around this issue, a known working older commit will be used.
+
+`git checkout b28ca17`
+
+#### Rootrouter (required)
+
+Needed for the bot to start correctly and the dashboard to load.
+
+`nano Zeppelin/backend/src/api/start.ts`
+Press Ctrl-W and type `initAuth` and press Enter.
+
+In each of the 4 lines:
+```
+initAuth(app);
+initGuildsAPI(app);
+initArchives(app);
+initDocs(app);
+```
+
+Change `app` to `rootRouter` so that it looks like this:
+
+```
+initAuth(rootRouter);
+initGuildsAPI(rootRouter);
+initArchives(rootRouter);
+initDocs(rootRouter);
+```
+
+Press Ctrl-X, Y, and Enter to save and close.
+
+#### Embeds in Tags
+
+Tags in the current code are text only. In order to use embeds, some code needs to be changed.
+
+`nano Zeppelin/backend/src/plugins/Tags/types.ts`
+
+Look for `export const zTag = z.union([z.string(), zEmbedInput]);`
+
+Change it to
+
+```
+const zEmbeds = z.object({ embeds: z.array(zEmbedInput) });
+export const zTag = z.union([z.string(), zEmbeds]);
+```
+
+Press Ctrl-X, Y, and Enter to save and close.
