+# Help
+
+## Running the tests
+
+Running the tests involves running `cmake -G` and then using the build command appropriate for your platform.
+Detailed instructions on how to do this can be found on the [Running the Tests][cpp-tests-instructions] page for C++ on exercism.org.
+
+## Passing the Tests
+
+Get the first test compiling, linking and passing by following the [three rules of test-driven development][three-laws-of-tdd].
+Create just enough structure by declaring namespaces, functions, classes, etc., to satisfy any compiler errors and get the test to fail.
+Then write just enough code to get the test to pass.
+Once you've done that, uncomment the next test by moving the following line past the next test.
+
+```C++
+#if defined(EXERCISM_RUN_ALL_TESTS)
+```
+
+This may result in compile errors as new constructs may be invoked that you haven't yet declared or defined.
+Again, fix the compile errors minimally to get a failing test, then change the code minimally to pass the test, refactor your implementation for readability and expressiveness and then go on to the next test.
+
+Try to use standard C++17 facilities in preference to writing your own low-level algorithms or facilities by hand.

+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit pangram.cpp pangram.h` command.
+This command will upload your solution to the Exercism website and print the solution page's URL.
+
+It's possible to submit an incomplete solution which allows you to:
+
+- See how others have completed the exercise
+- Request help from a mentor
+
+## Need to get help?
+
+If you'd like help solving the exercise, check the following pages:
+
+- The [C++ track's documentation](https://exercism.org/docs/tracks/cpp)
+- [Exercism's programming category on the forum](https://forum.exercism.org/c/programming/5)
+- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
+
+Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
+
+To get help if you're having trouble, you can use one of the following resources:
+
+- [`c++-faq` tag on StackOverflow](https://stackoverflow.com/tags/c%2b%2b-faq/info)
+- [C++ FAQ from isocpp.com](https://isocpp.org/faq)

+# Pangram
+
+Welcome to Pangram on Exercism's C++ Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Introduction
+
+You work for a company that sells fonts through their website.
+They'd like to show a different sentence each time someone views a font on their website.
+To give a comprehensive sense of the font, the random sentences should use **all** the letters in the English alphabet.
+
+They're running a competition to get suggestions for sentences that they can use.
+You're in charge of checking the submissions to see if they are valid.
+
+```exercism/note
+Pangram comes from Greek, παν γράμμα, pan gramma, which means "every letter".
+
+The best known English pangram is:
+
+> The quick brown fox jumps over the lazy dog.
+```
+
+## Instructions
+
+Your task is to figure out if a sentence is a pangram.
+
+A pangram is a sentence using every letter of the alphabet at least once.
+It is case insensitive, so it doesn't matter if a letter is lower-case (e.g. `k`) or upper-case (e.g. `K`).
+
+For this exercise we only use the basic letters used in the English alphabet: `a` to `z`.
