In addition to the libraries used by bitcoin, LBRYcrd also uses [icu4c](https://github.com/unicode-org/icu/tree/master/icu4c).

 ## Installation
 
 Latest binaries are available from https://github.com/lbryio/lbrycrd/releases. There is no installation procedure; the CLI binaries will run as-is and will have any uncommon dependencies statically linked into the binary. The QT GUI is not supported. LBRYcrd is distributed as a collection of executable files; traditional installers are not provided.

+#### Use with CLion
+
 CLion has not traditionally supported Autotools projects, although some progress on that is now in the works. We do include a cmake build file for compiling lbrycrd. See contrib/cmake. Alas, CLion doesn't support external projects in cmake, so that particular approach is also insufficient. CLion does support "compile_commands.json" projects. Fortunately, this can be easily generated for lbrycrd like so:
-```
+
+```sh
 pip install --user compiledb
 ./autogen.sh && ./configure --enable-static=no --enable-shared --with-pic --without-gui CXXFLAGS="-O0 -g" CFLAGS="-O0 -g" # or whatever normal lbrycrd config
 compiledb make -j10
 ```
+
 Then open the newly generated compile_commands.json file as a project in CLion. Debugging is supported if you compiled with `-g`. To enable that you will need to create a target in CLion by going to File -> Settings -> Build -> Custom Build Targets. Add an empty target with your choice of name. From there you can go to "Edit Configurations", typically found in a drop-down at the top of the editor. Add a Custom Build Application, select your new target, select the compiled file (i.e. test_lbrycrd or lbrycrdd, etc), and then add any necessary command line parameters. Ensure that there is nothing in the "Before launch" section.
