 ## Compile LPython
 
-Create a Conda environment using the preexisting environment.yml file:
-
-    conda env create -f environment.yml
-    conda activate lp
-
 Install required packages (Linux - 64 bit):
 
-    sudo apt install binutils-dev zlib1g-dev
+```bash
+sudo apt install binutils-dev
+```
 
 Clone LPython
 
-    git clone https://github.com/lcompilers/lpython.git
-    cd lpython
+```bash
+git clone https://github.com/lcompilers/lpython.git
+cd lpython
+```
+
+Create a Conda environment using the preexisting environment.yml file:
+
+```bash
+conda env create -f environment.yml
+conda activate lp
+```
 
 Create autogenerated files (choose the command for your platform):
 
-    ./build0.sh      # macOS/Linux
-    call build0.bat  # Windows
+```bash
+./build0.sh      # macOS/Linux
+call build0.bat  # Windows
+```
 
 Compile LPython:
 
-    cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_LLVM=yes -DWITH_STACKTRACE=yes -DWITH_LFORTRAN_BINARY_MODFILES=no .
-    cmake --build . -j16
+```bash
+cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_LLVM=yes -DWITH_STACKTRACE=yes -DWITH_LFORTRAN_BINARY_MODFILES=no .
+cmake --build . -j16
+```
 
 ## Tests:
 
 Run tests:
 
-    ctest
-    ./run_tests.py
+```bash
+ctest
+./run_tests.py
+```
 
 Also, run the integration tests:
 
-    ./integration_tests/run_tests.py
+```bash
+./integration_tests/run_tests.py
+```
 
 ## Examples
 
 You can run the following examples by hand in a terminal:
 
-    ./src/bin/lpython examples/expr2.py
-    ./a.out
-    ./src/bin/lpython --show-ast examples/expr2.py
-    ./src/bin/lpython --show-asr examples/expr2.py
-    ./src/bin/lpython --show-cpp examples/expr2.py
-    ./src/bin/lpython --show-llvm examples/expr2.py
+```bash
+./src/bin/lpython examples/expr2.py
+./a.out
+./src/bin/lpython --show-ast examples/expr2.py
+./src/bin/lpython --show-asr examples/expr2.py
+./src/bin/lpython --show-cpp examples/expr2.py
+./src/bin/lpython --show-llvm examples/expr2.py
