I'm trying to make my paragraphs, images and tables indented (hanging) in markdown but when I try to just Tab the (control signals for each instruction), it turns into a box for some reason.
I would like my readme file to look something like this:

11. **Main Control Unit**
We have used filled ROM with values of every opcodes' signals as a decoder to generate all possible signals to control each instruction from its opcode in this datapath. In our design we chose to a ROM that works as a decoder and connected to a splitter that group signals in their specified place as shown in the table below:
| Bits | Singal/Signals |
| --- | --- |
| 0-1 | WBdata |
| 2 | MemWr |
| 3 | MemRd |
| 4 | AluSrc |
| 5 | ExtOp |
| 6 | RegWr |
| 7-8 | RegDst |
The Control Unit's purpose is to produce the signals to the Register file, ALU, and Data Memory. There is a single input for the 5-bit opcode, and 7 signal outputs. The outputs are as following:
- WBdata (bit 0&1): Selects whether the data on BusW should be coming from the ALU or the Data memory.
- MemWr (bit 2): for store instructions.
- MemRd (bit 3): for load instructions.
- AluSrc (bit 4): Selects whether the 2nd ALU input should be from BusB or the extended 5-bit immediate.
- ExtOp (bit 5): Controls the extension of the 5-bit immediate
- RegWr (bit 6): Enables the writing of the registers in the register file.
- RegDst (bit 7 & 8): Chooses which register should be the register destination.
