A short change log records what changed, when, why and what happened afterward. It is useful when several people help with one setup or an intermittent issue returns. Keep it focused on relevant settings and nonsecret references rather than turning it into a copy of every credential and viewing session.
Record one change at a time
A change to the server address, guide mapping and local cache in one step makes the result difficult to interpret. Where practical, separate the actions and note the outcome of each. Preserve the original value privately when a reversal may be needed.
Use observations rather than conclusions
Write “guide populated after refresh” rather than “server fixed forever.” The first describes what happened; the second claims more than the evidence supports. Note the test conditions and any remaining uncertainty.
Retire obsolete sensitive notes
A troubleshooting file can accumulate old URLs and passwords if used carelessly. Keep secrets in their proper private record and remove stale diagnostic exports. The log should explain decisions without becoming an access-data archive.

An example to work through
“20:15: remapped City News to its East guide id; current news title now matches” is a compact useful entry. It preserves the reason and result without exposing the account.
