Now you can find the app on the Google Play.

1. Separate subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how

If your commit has a body, then separate it from subject using blank line. For Example:

Derezz the master control program

MCP turned out to be evil and had become intent on world domination.
This commit throws Tron's disc into MCP (causing its deresolution)
and turns it back into a chess game.

But not every commit requires both a subject and a body. Sometimes a single line is fine, especially when the change is so simple that no further context is necessary. For example:

Fix typo in introduction to user guide

50 characters is not a hard limit, just a rule of thumb. Keeping subject lines at this length ensures that they are readable, and forces the author to think for a moment about the most concise way to explain what’s going on.

To remove any confusion, here’s a simple rule to get it right every time.

A properly formed Git commit subject line should always be able to complete the following sentence:

• If applied, this commit will your subject line here

Git never wraps text automatically. When you write the body of a commit message, you must mind its right margin, and wrap text manually.

The recommendation is to do this at 72 characters, so that Git has plenty of room to indent text while still keeping everything under 80 characters overall.

This commit from Bitcoin Core is a great example of explaining what changed and why:

commit eb0b56b19017ab5c16c745e6da39c53126924ed6
Author: Pieter Wuille <[email protected]>

Simplify serialize.h's exception handling

Remove the 'state' and 'exceptmask' from serialize.h's stream implementations, as well as related methods.

As exceptmask always included 'failbit', and setstate was always called with bits = failbit, all it did was immediately raise an exception. Get rid of those variables, and replace the setstate with direct exception throwing (which also removes some dead code).

As a result, good() is never reached after a failure (there are only 2 calls, one of which is in tests), and can just be replaced by !eof().

fail(), clear(n) and exceptions() are just never called. Delete them.

Take a look at the full diff and just think how much time the author is saving fellow and future committers by taking the time to provide this context here and now. If he didn’t, it would probably be lost forever.

In most cases, you can leave out details about how a change has been made. Code is generally self-explanatory in this regard (and if the code is so complex that it needs to be explained in prose, that’s what source comments are for). Just focus on making clear the reasons why you made the change in the first place—the way things worked before the change (and what was wrong with that), the way they work now, and why you decided to solve it the way you did.

This rules are based on this article: https://chris.beams.io/posts/git-commit/

1. Use hyphen as separators of words
2. Create a new branch to implement a new feautre
3. Add prefix to the name of a new branch
4. Add Issue id

DO:

temporary-version

DON'T:

temporary_version

DON'T:

temporaryVersion

Every time when you need to implement a new feature you must create a new branch. Ensure that the new branch is based on the develop branch. Keep in mind that the best practice is when one branch solves one Issue.

Also don't forget to push your changes to develop branch, not to master.

If you going to create a new branch to solve some Issue then add the id of that Issue.
