+# **How to Save Data at SwissFEL: A Totally Serious Guide**  
+
 **Hey, look at my nice data!**  
-What a load of bs!  
+*What a load of BS!*  
+
 **Oy, no need to be rude!**  
-I'm not!  I mean, what a load of beam synchronous data!  
-**Well, thanks, but it is not all saved**
-Bummer, how were you saving it?  
-**I used this cool command line script bs...**  
-I'm going to stop you there  
+*I’m not! I mean, what a load of **Beam Synchronous** data!*  
+
+**Well, thanks... but it’s not all saved.**  
+*Bummer. How were you saving it?*  
+
+**I used this cool command-line script `bs...`**  
+*Ooooh... I’m going to stop you right there.*  
+
 **But my BS command works; there must be a problem with the sources!**  
-Try each one individually with the bs command..  
-**OK, hang on, what the!  They work, the both save individually!**  
-Yes the issue is when you try and save sources from different IOCs/devices with the bs command 
+*Calm down, detective, try saving each source individually with the `bs` command...*  
+
+**OK, hang on... what the?! They *both* save fine on their own!**  
+*Yep, the issue is when you try and save sources from different IOCs/devices with the `bs` command. The data is taken from the **dispatcher**. If the two sources don’t arrive at the dispatcher within a small time window, only the first source is sent in the message. Different sources arrive at the dispatcher at **different times**.*  
+
+**What type of BS is that?! I can't wait and wait...**  
+*Good question. Some BS data comes from **pipelines**, where calculations and moving data around **takes time**. You’re not just saving numbers—you’re saving processed results.*  
+
+**Pipelines?! I want data, not plumbing problems!**  
+*Think of pipelines as hardworking elves doing data analysis behind the scenes. No pipelines, more work for you.*  
+
+**Alright, I’m sold. But how do I save multiple sources without all this drama?**  
+*You need to save from the **data buffer**. The system can handle sources arriving at slightly different times there.*  
+
+**The data buffer? How?**  
+*You’ve got plenty of tools for accessing it:*  
+- **DataHub** (don't ask about a front-end)  
+- **Data API** (if you speak code)  
+- **Eco, Slic, Service Now, Concour, Time** (some might not work).  
+
+**Steady your sources, Doc Brown, I just checked my data and one of the sources isn't running at 100 Hz and missing data, I told you the source was the problem**  
+
+*Missing data isn't necessarily a problem; the approaches above can handle missing pulse IDs and return you all the data that is in the data buffer*
+
+**Pulse IDs? Does my data need to prove its age?**  
+
+*No, its a way to sort data, with bs data every shot had a unique pulse ID.  You can use SwissFEL data analysis packages to match arrays with missing shots in for you*
+
+**Cool! Anything else I should know?**  
+*Yes: the databuffer can’t clean your desk at PiA*
+
+**✅ Do Say:**
+*Pulse IDs rock my world!*
+
+**❌ Don’t Say:** 
+*Beam synchronous PV*
